Subject: sony-laptop - remove private workqueue, use keventd instead

If we reschedule work instead of having work function sleep for 10 msecs
between reads from kfifo we can safely use the main workqueue (keventd)
and not bother with creating driver-private one.

Subject: ACPI: Disable explicit power state retrieval on fans

If the ACPI power state can be got both directly and indirectly,
we prefer to get it indirectly.

https://bugzilla.redhat.com/show_bug.cgi?id=531916 describes a
system with a _PSC method for the fan that always returns "on".
There's no benefit in us always requesting the state of the fan
when performing transitions - we want to do everything we can
to ensure that the fan turns on when it should do, not risk
hardware damage by believing the hardware when it tells us the
fan is already on. Given that the Leading Other OS(tm) works fine
on this machine, it seems likely that it behaves in much this way.

Subject: firewire: add fw_csr_string() helper function

The core (sysfs attributes), the firedtv driver, and possible future
drivers all read strings from some configuration ROM directory.  Factor
out the generic code from show_text_leaf() into a new helper function,
modified slightly to handle arbitrary buffer sizes.

Subject: firewire: qualify config ROM cache pointers as const pointers

Several config ROM related functions only peek at the ROM cache; mark
their arguments as const pointers.  Ditto fw_device.config_rom and
fw_unit.directory, as the memory behind them is meant to be write-once.

Subject: scc_pata: fix module unloading

scc_pata host driver predated module unloading support for IDE host
drivers so even though it supports PCI hot-unplug and implements
PCI device ->remove method it doesn't allow module removal.  Fix it.

Add missing __init/__exit tags to module_init/module_exit functions
while at it (from Peter Huewe).

Subject: icside: bring back ->maskproc method

Bring back ->maskproc method since it is still needed for proper operation,
as noticed by Russell King:

This patch reverts changes done in commit dff8817 (I became confused due to
non-standard & undocumented ->maskproc method, anyway sorry about that).

Having manually bisected kernel versions, I've narrowed it down to some
change between 2.6.30 and 2.6.31.  There's not much which has changed
between the two kernels, but one change stands out like a sore thumb:

+static int pdc202xx_test_irq(ide_hwif_t *hwif)
+{
+       struct pci_dev *dev     = to_pci_dev(hwif->dev);
+       unsigned long high_16   = pci_resource_start(dev, 4);
+       u8 sc1d                 = inb(high_16 + 0x1d);
+
+       if (hwif->channel) {
+               /*
+                * bit 7: error, bit 6: interrupting,
+                * bit 5: FIFO full, bit 4: FIFO empty
+                */
+               return ((sc1d & 0x50) == 0x40) ? 1 : 0;
+       } else  {
+               /*
+                * bit 3: error, bit 2: interrupting,
+                * bit 1: FIFO full, bit 0: FIFO empty
+                */
+               return ((sc1d & 0x05) == 0x04) ? 1 : 0;
+       }
+}

Reading the (documented as a 32-bit) system control register when the
interface is idle gives: 0x01da110c

So, the byte at 0x1d is 0x11, which is documented as meaning that the
primary and secondary FIFOs are empty.

The code above, which is trying to see whether an IRQ is pending, checks
for the IRQ bit to be one, and the FIFO bit to be zero - or in English,
to be non-empty.

Since during a BM-DMA read, the FIFOs will naturally be drained to the
PCI bus, the chance of us getting to the interface before this happens
are extremely small - and if we don't, it means we decide not to service
the interrupt.  Hence, the screaming interrupt problem with drivers/ide.

Fix this by only indicating an interrupt is ready if both the interrupt
and FIFO empty bits are at '1'.

This bug only affects PDC20246/PDC20247 (Promise Ultra33) based cards,
and has been tested on 2.6.31 and 2.6.33-rc2.

Ready to get everything using unlocked_ioctl()

For ide_tape we just push down as this is legacy code anyway

Subject: [CPUFREQ] Processor Clocking Control interface driver

Processor Clocking Control (PCC) is an interface between the BIOS and OSPM.
Based on the server workload, OSPM can request what frequency it expects
from a logical CPU, and the BIOS will achieve that frequency transparently.

This patch introduces driver support for PCC. OSPM uses the PCC driver to
communicate with the BIOS via the PCC interface.

There is a Documentation file that provides a link to the PCC
Specification, and also provides a summary of the PCC interface.

Currently, certain HP ProLiant platforms implement the PCC interface. However,
any platform whose BIOS implements the PCC Specification, can utilize this
driver.

V2 --> V1 changes (based on Dominik's suggestions):
- Removed the dependency on CPU_FREQ_TABLE
- "cpufreq_stats" will no longer PANIC. Actually, it will not load anymore
because it is not applicable.
- Removed the sanity check for target frequency in the ->target routine.

NOTE: A patch to sanitize the target frequency requested by "ondemand" is
needed to ensure that the target freq < policy->min.

Can this driver be queued up for the 2.6.33 tree?

Subject: ide/ide-cs: fix order of releasing resources

ide_detach() called first ide_release() and then release_region(). This
produced the following warnings:

  Trying to free nonexistent resource <000000000000c10e-000000000000c10e>
  Trying to free nonexistent resource <000000000000c100-000000000000c107>

This is true, because the callchain inside ide_release() is:

  ide_release -> pcmcia_disable_device -> pcmcia_release_io

So, the whole io-block is already gone for release_region(). To fix
this, just swap the order of releasing (and remove the now obsolete
shadowing).

bzolnier:
- release resources in ide_release() to fix ordering of events
- remove stale FIXME note while at it

Subject: ARM: SAMSUNG: serial: Modify console initialization.

This patch modifies s3c24xx_serial_initconsole function to accept multiple
platform UART information structures. This is required on platforms that have
differences among the instances of UART ports. As an example, the FIFO sizes
could be different for each UART instance and hence multiple platform UART
information structures would be needed.

This patch also modifies the s3c24xx_console_init macro since it wraps the
call to the s3c24xx_serial_initconsole function.

Subject: alim15x3: fix PIO timings calculations

Just use the standard ide_timing_compute() helper to calculate
PIO timings.  This fixes many issues with the open-coded version
like potential recovery timings underclocking or not accounting
for the enhanced cycle time specified by the device.

Based on libata pata_ali host driver.

Just use the standard ide_timing_compute() helper to calculate
PIO and MWDMA timings.  This fixes some issues with the open-coded
version like allowing faster MWDMA timings than the ones required
by the current PIO mode or not accounting for the enhanced MWDMA
cycle time specified by the device.

Based on libata pata_cmd64x host driver.

  * CYPRESS CY82C693 chipset IDE controller
  *
  * The CY82C693 chipset is used on Digital's PC-Alpha 164SX boards.
- * Writing the driver was quite simple, since most of the job is
- * done by the generic pci-ide support.
- * The hard part was finding the CY82C693's datasheet on Cypress's
- * web page :-(. But Altavista solved this problem :-).
- *
- *
- * Notes:
- * - I recently got a 16.8G IBM DTTA, so I was able to test it with
- *   a large and fast disk - the results look great, so I'd say the
- *   driver is working fine :-)
- *   hdparm -t reports 8.17 MB/sec at about 6% CPU usage for the DTTA
- * - this is my first linux driver, so there's probably a lot  of room
- *   for optimizations and bug fixing, so feel free to do it.
- * - if using PIO mode it's a good idea to set the PIO mode and
- *   32-bit I/O support (if possible), e.g. hdparm -p2 -c1 /dev/hda
- * - I had some problems with my IBM DHEA with PIO modes < 2
- *   (lost interrupts) ?????
- * - first tests with DMA look okay, they seem to work, but there is a
- *   problem with sound - the BusMaster IDE TimeOut should fixed this
- *
- * Ancient History:
- * AMH@1999-08-24: v0.34 init_cy82c693_chip moved to pci_init_cy82c693
- * ASK@1999-01-23: v0.33 made a few minor code clean ups
- *                       removed DMA clock speed setting by default
- *                       added boot message
- * ASK@1998-11-01: v0.32 added support to set BusMaster IDE TimeOut
- *                       added support to set DMA Controller Clock Speed
- * ASK@1998-10-31: v0.31 fixed problem with setting to high DMA modes
- *                       on some drives.
- * ASK@1998-10-29: v0.3 added support to set DMA modes
- * ASK@1998-10-28: v0.2 added support to set PIO modes
- * ASK@1998-10-27: v0.1 first version - chipset detection

- * is at 20 MHz (I have DX2/80, I tried PCI at 40, but I got random
- * lockups). I tried the OCTEK double speed CD-ROM and
- * it does not work! But I can't boot DOS also, so it's probably
- * hardware fault. I have connected Conner 80MB, the Seagate 850MB (no
- * problems) and Seagate 1GB (as slave, WD as master). My experiences
- * with the third, 1GB drive: I got 3MB/s (hdparm), but sometimes
- * it slows to about 100kB/s! I don't know why and I have
- * not this drive now, so I can't try it again.
- * I write this driver because I lost the paper ("manual") with
- * settings of jumpers on the card and I have to boot Linux with
- * Loadlin except LILO, cause I have to run the setupvic.exe program
- * already or I get disk errors (my test: rpm -Vf
- * /usr/X11R6/bin/XF86_SVGA - or any big file).
- * Some numbers from hdparm -t /dev/hda:
- * Timing buffer-cache reads:   32 MB in  3.02 seconds =10.60 MB/sec
- * Timing buffered disk reads:  16 MB in  5.52 seconds = 2.90 MB/sec
- * I have 4 Megs/s before, but I don't know why (maybe changes
- * in hdparm test).
- * After release of 0.1, I got some successful reports, so it might work.
- *
- * The main problem with OPTi is that some timings for master
- * and slave must be the same. For example, if you have master
- * PIO 3 and slave PIO 0, driver have to set some timings of
- * master for PIO 0. Second problem is that opti621_set_pio_mode
- * got only one drive to set, but have to set both drives.
- * This is solved in compute_pios. If you don't set
- * the second drive, compute_pios use ide_get_best_pio_mode
- * for autoselect mode (you can change it to PIO 0, if you want).
- * If you then set the second drive to another PIO, the old value
- * (automatically selected) will be overrided by yours.
- * There is a 25/33MHz switch in configuration
- * register, but driver is written for use at any frequency.
- *
- * Version 0.1, Nov 8, 1996
- * by Jaromir Koutek, for 2.1.8.
- * Initial version of driver.
- *
- * Version 0.2
- * Number 0.2 skipped.
- *
- * Version 0.3, Nov 29, 1997
- * by Mark Lord (probably), for 2.1.68
- * Updates for use with new IDE block driver.
- *
- * Version 0.4, Dec 14, 1997
- * by Jan Harkes
- * Fixed some errors and cleaned the code.
- *
- * Version 0.5, Jan 2, 1998
- * by Jaromir Koutek
- * Updates for use with (again) new IDE block driver.
- * Update of documentation.
- *
- * Version 0.6, Jan 2, 1999
- * by Jaromir Koutek
- * Reversed to version 0.3 of the driver, because
- * 0.5 doesn't work.

Subject: ide-timings: use ->pio_mode value to determine fastest PIO speed

Use the current PIO mode value instead of the physical maximum one
to determine the fastest allowed PIO for shared PIO/DMA timings.

Affected host drivers: amd74xx and via82cxxx.

XFER_SW_DMA_0 mode should be excluded from the extended cycle
timing computations.

[ This is just a documentation fix -- code inside the affected
  'if' block already makes sure to accept only PIO modes. ]

Subject: UBI: mark few variables as __initdata

The @mtd_devs and @mtd_dev_param variables are used only during the
initialization, and all functions that use the variables have
the __init prefix. This means we can safely mark the variables
as __initdata, which is a tiny optimization.

Impact: tiny RAM consumption optimization when UBI is used as a kernel
        module.

Subject: UBI: fix attaching error path

In the error path of 'ubi_attach_mtd_dev()' we have a tricky situation:
we have to release things differently depending on at which point
the failure happening. Namely, if @ubi->dev is not initialized, we have
to free everything ourselves. But if it was, we should not free the @ubi
object, because it will be freed in the 'dev_release()' function. And
we did not get this situation right.

This patch introduces additional argument to the 'uif_init()' function.
On exit, this argument indicates whether the final 'free(ubi)' will
happen in 'dev_release()' or not. So the caller always knows how to
properly release the resources.

Impact: all memory is now correctly released when UBI fails to attach
        an MTD device.

Subject: UBI: simplify debugging return codes

UBI debugging functions were a little bit over-engineered and
returned more error codes than needed, and the callers had to
do useless checks. Simplify the return codes.

Impact: only debugging code is affected, which means that for
        non-developers this is a no-op patch.

Subject: UBI: add write checking

Add an extra debugging check function which validates writes.
After every write it reads the data back, compares it with the
original data, and complains if they mismatch.

Useful for debugging. No-op if extra debugging checks are disabled.

Subject: fsldma: reduce kernel text size

Some of the functions are written in a way where they use multiple reads
and writes where a single read/write pair could suffice. This shrinks the
kernel text size measurably, while making the functions easier to
understand.

Remove some unused members from the fsldma data structures. A few trivial
uses of struct resource were converted to use the stack rather than keeping
the memory allocated for the lifetime of the driver.

From a4f56d4b103d4e5d1a59a9118db0185a6bd1a83b Mon Sep 17 00:00:00 2001
From: Ira Snyder <iws@ovro.caltech.edu>
Date: Wed, 6 Jan 2010 13:34:01 +0000
Subject: fsldma: rename struct fsl_dma_chan to struct fsldma_chan

This is the beginning of a cleanup which will change all instances of
"fsl_dma" to "fsldma" to match the name of the driver itself.

Subject: fsldma: rename dest to dst for uniformity

Most functions in the standard library use "dst" as a parameter, rather
than "dest". This renames all use of "dest" to "dst" to match the usual
convention.

From d3f620b2c4fecdc8e060b70e8d92d29fc01c6126 Mon Sep 17 00:00:00 2001

Subject: fsldma: simplify IRQ probing and handling

The IRQ probing is needlessly complex. All off the 83xx device trees in
arch/powerpc/boot/dts/ specify 5 interrupts per DMA controller: one for the
controller, and one for each channel. These interrupts are all attached to
the same IRQ line.

This causes an interesting situation if two channels interrupt at the same
time. The per-controller handler will handle the first channel, and the
per-channel handler will handle the remaining channels.

Instead of this mess, we fix the bug in the per-controller handler, and
make it handle all channels that generated an interrupt. When a
per-controller handler is specified in the device tree, we prefer to use
the shared handler instead of the per-channel handler.

The 85xx/86xx controllers do not have a per-controller interrupt, and
instead use a per-channel interrupt. This behavior has not been changed.

conflicts. These have been changed to "struct dma_chan *dchan" instead.

From 9c3a50b7d7ec45da34e73cac66cde12dd6092dd8 Mon Sep 17 00:00:00 2001
From: Ira Snyder <iws@ovro.caltech.edu>
Date: Wed, 6 Jan 2010 13:34:06 +0000
Subject: fsldma: major cleanups and fixes

Fix locking. Use two queues in the driver, one for pending transacions, and
one for transactions which are actually running on the hardware. Call
dma_run_dependencies() on descriptor cleanup so that the async_tx API works
correctly.

There are a number of places throughout the code where lists of descriptors
are freed in a loop. Create functions to handle this, and use them instead
of open-coding the loop each time.

Subject: ARM: SAMSUNG: Use PLAT_SAMSUNG instead of PLAT_S3C

As part of the development process, it is hoped PLAT_S3C is either removed
from all of the PLAT_SAMSUNG derived platforms or removed entirely. It is
also better to use PLAT_SAMSUNG as this is the current base of all Samsung
devices.

Change the two places that use PLAT_S3C to use PLAT_SAMSUNG

Subject: ataflop: Killl warning about unused variable flags

After commit e0c0978699a83f26f2341f7eedc1463b79e31aff ("ataflop: remove
buggy/commented-out IRQ disable from do_fd_request()") the `flags' variable
became unused:

drivers/block/ataflop.c:1473: warning: unused variable 'flags'

Hence remove it.

From c9404c9c392d557a4687c4cbda022b03cb787ce9 Mon Sep 17 00:00:00 2001
From: Adam Buchbinder <adam.buchbinder@gmail.com>
Date: Fri, 18 Dec 2009 15:40:42 -0500
Subject: Fix misspelling of "should" and "shouldn't" in comments.

Some comments misspell "should" or "shouldn't"; this fixes them. No code changes.

Subject: drm/radeon/kms: add support for hw i2c on r1xx-r5xx

wire hw i2c support into radeon i2c algo.

fixes merged:
- handle bus probing correctly
- use meaningful error numbers
- abort if transaction fails
- The line mapping is different depending on the asic.
- protect hw i2c engine with a mutex
- rs300 doesn't have a pin select bit
- r200 has a different pin select setup

Subject: drm/radeon/kms: add workaround for rn50/rv100 servers

Some servers have two VGA ports but only report
one in the bios connector tables.  On these systems
always set up the TV DAC so that it displays properly
even if the bios is wrong.

Subject: drm/radeon/kms: add support for hardcoded edids in rom (v2)

Some servers hardcode an edid in rom so that they will
work properly with KVMs.  This is a port of the relevant
code from the ddx.

[airlied: reworked to validate edid at boot stage - and
remove special quirk, if there is a valid EDID in the BIOS rom
we'll just try and use it.]

Subject: drm/radeon/kms: rework pll algo selection

Rework the pll algo selection so that the pll algo
in use can be selected more easily.  This allows
us to select different pll divider selection algos
for specific monitors that work better with one algo
or the other.  This is needed for the next patch which
adds an LVDS pll quirk for a specific notebook.

Subject: drm/radeon/kms: add pll quirk for toshiba laptop panel

The panel on the Toshiba A300-1BU laptop does not like the
PLL dividers selected by the avivo pll algo, but works fine
using the older method.  Add a quirk to handle it.

Should fix fdo bug 26358.

Subject: drm/radeon/kms/r600: reduce gpu cache flushing

Only flush the gpu caches before we submit a fence.
This leads to a small performance boost when we take
the extra gpu cache flushes out of the ddx and mesa.
Once this patch is in and the drm version is bumped,
we can remove the flushes from the ddx and drm.

Also, remove the extra cache flushes from the blit
routine.

Subject: drm/radeon/kms: pull power mode info from bios tables (v3)

The general idea is to validate the current hw state
against the set of power states and select a power
state based on that.  This patch just pulls the power
states from the bios and prints the information.  It
is not currently hooked up in the actual power management
code.  Hooking it up will require reworking the the current
power state selection code and will be handled in a future
patch.

Additionally, we'd need to decide on some default lower
power states for cards without power tables.

v2 - increment state_index after checking for default state
v3 - fix typo in pm init on pre-atom cards, handle pre-atom
cards without x86 bioses

Subject: drm/radeon/kms: add a power state type based on power state flags

The idea is to flag a power state with a certain type and use
that type to decide on what state to select.  On r6xx+, we
select a state and then transition between clock modes in that
state.  On pre-r6xx, we transition between states directly.

Subject: drm/radeon/kms: dynclks fixes

- only r4xx/r5xx/rs6xx/rs740 have clock gating atom table,
so disable it on r6xx.  it's already disabled on r7xx
- check to make sure the clock_gating hook exists before
calling it.  This avoids a segfault on asics without
that function.
- remove unused static power management function.

Subject: drm/radeon/kms: bogus cs recorder utilities

This add an utilities function radeon_ib_bogus_add which will
save an ib into a list of ib which can then be dumped using
debugfs. Once dumped the ib is removed from the list. This
should allow to save & capute ib for further debugging.

From bcc1c2a1d22974215e39dc87ce746ba9a39223e5 Mon Sep 17 00:00:00 2001
From: Alex Deucher <alexdeucher@gmail.com>
Date: Tue, 12 Jan 2010 17:54:34 -0500
Subject: drm/radeon/kms: add initial Evergreen support (Radeon HD 5xxx)

This adds initial Evergreen KMS support, it doesn't include
any acceleration features or interrupt handling yet.

Major changes are DCE4 handling for PLLs for the > 2 crtcs.

From 3ad2f3fbb961429d2aa627465ae4829758bc7e07 Mon Sep 17 00:00:00 2001
From: Daniel Mack <daniel@caiaq.de>
Date: Wed, 3 Feb 2010 08:01:28 +0800
Subject: tree-wide: Assorted spelling fixes

In particular, several occurances of funny versions of 'success',
'unknown', 'therefore', 'acknowledge', 'argument', 'achieve', 'address',
'beginning', 'desirable', 'separate' and 'necessary' are fixed.

Subject: drm: introduce drm_gem_object_[handle_]unreference_unlocked

This patch introduces the drm_gem_object_unreference_unlocked
and drm_gem_object_handle_unreference_unlocked functions that
do not require holding struct_mutex.

drm_gem_object_unreference_unlocked calls the new
->gem_free_object_unlocked entry point if available, and
otherwise just takes struct_mutex and just calls ->gem_free_object

Subject: Use drm_gem_object_[handle_]unreference_unlocked where possible

Mostly obvious simplifications.

The i915 pread/pwrite ioctls, intel_overlay_put_image and
nouveau_gem_new were incorrectly using the locked versions
without locking: this is also fixed in this patch.

From 9a1420d1185693b6e24719d3937a0c20a3e0e31d Mon Sep 17 00:00:00 2001
From: Dave Airlie <airlied@redhat.com>
Date: Wed, 3 Feb 2010 19:14:35 +1000
Subject: drm: switch all GEM/KMS ioctls to unlocked ioctl status.

These ioctls are all protected by their own locking mechanisms so
should be fine to not bother locking around.

Signed-off-by: Dave Airlie <airlied@redhat.com>

Subject: drivers/gpu/drm/drm_fb_helper.c: don't use private implementation of
 atoi()

Kernel has simple_strtol() which would be used as atoi().

This is quite the same fix as in 2cb96f86628d6e97fcbda5fe4d8d74876239834c
("fbdev: drop custom atoi from drivers/video/modedb.c") because code in
drivers/gpu/drm/drm_fb_helper.c is based on drivers/video/modedb.c.

Subject: drm/radeon/kms: r600/r700 command stream checker

This patch add cs checker to r600/r700 hw. Command stream checking
will rewrite some of the cs value in order to restrict GPU access
to BO size. This doesn't break old userspace but just enforce safe
value. It should break any things that was using the r600/r700 cs
ioctl to do forbidden things (malicious software), though we are
not aware of such things.

Here is the list of thing we check :
- enforcing resource size
- enforcing color buffer slice tile max, will restrict cb access
- enforcing db buffer slice tile max, will restrict db access

We don't check for shader bigger than the BO in which they are
supposed to be, such use would lead to GPU lockup and is harmless
from security POV, as far as we can tell (note that even checking
for this wouldn't prevent someone to write bogus shader that lead
to lockup).

This patch has received as much testing as humanly possible with
old userspace to check that it didn't break such configuration.
However not all the applications out there were tested, thus it
might broke some odd, rare applications.

Subject: drm/radeon/kms: Test rdev->bios centrally in
 combios_get_table_offset().
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

It's happened time and time again (most recently with the support for EDID
hardcoded in the BIOS ROM) that new code didn't check for rdev->bios being
non-NULL before triggering dereferences of it. This would result in an
oops/panic on setups with no BIOS ROM. Hopefully this central test will be
more robust.

Subject: drm/radeon/kms: set gart pages to invalid on unbind and point to
 dummy page

this uses a new entrypoint to invalidate gart entries instead of using 0.
Changed to rather than pointing to 0 address point empty entry to dummy
page. This might help to avoid hard lockup if for some wrong
reasons GPU try to access unmapped GART entry.

I'm not 100% sure this is going to work, we probably need to allocate
a dummy page and point all the GTT entries at it similiar to what AGP does.
but we can test this first I suppose.

Subject: drm/radeon/kms: fix r600/r700 cs checker to avoid double kfree

radeon_cs kfree the tracker structure but for r6xx/r7xx we want
to kfree it inside the parse function because we share it with
the UMS code path. Set tracker to NULL after freeing it will
avoid double free.

Subject: drm/radeon/kms: fix indirect buffer management V2

There is 3 different distinct states for an indirect buffer (IB) :
  1- free with no fence
  2- free with a fence
  3- non free (fence doesn't matter)
Previous code mixed case 2 & 3 in a single one leading to possible
catastrophique failure. This patch rework the handling and properly
separate each case. So when you get ib we set the ib as non free and
fence status doesn't matter. Fence become active (ie has a meaning
for the ib code) once the ib is scheduled or free. This patch also
get rid of the alloc bitmap as it was overkill, we know go through
IB pool list like in a ring buffer as the oldest IB is the first
one the will be free.

Fix :
https://bugs.freedesktop.org/show_bug.cgi?id=26438
and likely other bugs.

V2 remove the scheduled list, it's useless now, fix free ib scanning

Subject: drm/radeon/kms: fix bo's fence association

Previous code did associate fence to bo before the fence was emited
and it also didn't lock protected access to ttm sync_obj member.
Both of this flaw leads to possible race between different code
path. This patch fix this by associating fence only once the fence
is emitted and properly lock protect access to sync_obj member of
ttm.

Fix:

Subject: ACPI: remove superfluous NULL pointer check from
 acpi_processor_get_throttling_info()

Dan's list contains:

drivers/acpi/processor_throttling.c +1139 acpi_processor_get_throttling_info(11) warning: variable derefenced before check 'pr'

acpi_processor_get_throttling_info() is never called with pr == NULL.

[ bart: the potential NULL pointer dereference was finally fixed in
  (much later than mine) commit 5cfa245 but my patch is still valid ]

Subject: imx-serial-excessive-status-clearing-on-break.patch

cc: Sasha Hauer <kernel@pengutronix.de>

We noticed that we were only able to communicate once with a GSM module
per session, if we powered down the module then the serial driver was
broken until reset, no traffic or /proc/interrupts activity could be
seen any more.

Volker noticed it was provoked by a long "break" seen on the wire when
the RX was not driven during powerdown, we discovered we could kill the
serial driver just by forcing RX low extenally for a little while.

I saw that the processing for BREAK in the driver gets too excited and
clears down all set bits in USR2, including that a character is pending.
This stops all further characters getting processed.

The attached one-liner makes the serial driver immortal against BREAK.

Subject: power_supply: bq27x00: remove double endian swap

The bq27x00 registers are little endian, so just read them as such
and don't do double endian swap on LE machines.

This also gets rid of strange looking shift that was done after
reading 8bit register because endian swap in bq27x00_read() was
messing it up.

BQ27500 is newer fuel gauge chip from TI with slightly changed

ID for it and handle differences where needed. Also rename bq27200
functions to bq27x00, as they are no longer bq27200 specific.

Subject: drm/i915: Replace open-coded eviction in i915_gem_idle()

With the introduction of the hang-check, we can safely expect that
i915_wait_request() will always return even when the GPU hangs, and so
do not need to open code the wait in order to manually check for the
hang. Also we do not need to always evict all buffers, so only flush
the GPU (and wait for it to idle) for KMS, but continue to evict for UMS.

Subject: drm/i915: Keep MCHBAR always enabled

As we need more and more controls within MCHBAR for memory config and
power management, this trys to keep MCHBAR enabled from driver load and
only tear down in driver unload.

Subject: percpu: add __percpu sparse annotations to what's left

Add __percpu sparse annotations to places which didn't make it in one
of the previous patches.  All converions are trivial.

These annotations are to make sparse consider percpu variables to be
in a different address space and warn if accessed without going
through percpu accessors.  This patch doesn't affect normal builds.

Subject: smp: Use nr_cpus= to set nr_cpu_ids early

On x86, before prefill_possible_map(), nr_cpu_ids will be NR_CPUS aka
CONFIG_NR_CPUS.

Add nr_cpus= to set nr_cpu_ids. so we can simulate cpus <=8 are installed on
normal config.

-v2: accordging to Christoph, acpi_numa_init should use nr_cpu_ids in stead of
     NR_CPUS.
-v3: add doc in kernel-parameters.txt according to Andrew.

Subject: drm/radeon/kms: remove unused r600_gart_clear_page

r6xx/r7xx use the rs600 variant.  This old one just
confuses things.

Subject: drm/radeon/kms: Create asic structure for r300 pcie cards.

Setting global asic structure to point to different function
would cause problem in system where is multiple r300 cards
with different bus type.

r300_asic_pcie is just copy from r300_asic with gart tlb
functions replaced with pcie versions.

Subject: drm/radeon: Add asic hook for dma copy to r200 cards.

r200 cards have dma engine which can be used to tranfer data
between vram and system memory.

r300 dma engine registers match r200 dma engine. Enabling
dma copy for r200 is simple as hooking r200 asic to already
existing function r300_copy_dma.

Rename r300_dma_copy to r200_dma_copyto reflect that supports
starts from r200 cards.

v2: Created a new asic object for r200 cards.

Subject: drm/radeon/kms: simplify memory controller setup V2

Get rid of _location and use _start/_end also simplify the
computation of vram_start|end & gtt_start|end. For R1XX-R2XX
we place VRAM at the same address of PCI aperture, those GPU
shouldn't have much memory and seems to behave better when
setup that way. For R3XX and newer we place VRAM at 0. For
R6XX-R7XX AGP we place VRAM before or after AGP aperture this
might limit to limit the VRAM size but it's very unlikely.
For IGP we don't change the VRAM placement.

Tested on (compiz,quake3,suspend/resume):
PCI/PCIE:RV280,R420,RV515,RV570,RV610,RV710
AGP:RV100,RV280,R420,RV350,RV620(RPB*),RV730
IGP:RS480(RPB*),RS690,RS780(RPB*),RS880

RPB: resume previously broken

V2 correct commit message to reflect more accurately the bug
and move VRAM placement to 0 for most of the GPU to avoid
limiting VRAM.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The commit also introduces the HAVE_FB_IMX config that is to be selected from
the MX25 platform config. Once this commit gets merged, the two other i.MX
archs, ARCH_MX1 and ARCH_MX2, should follow this one.

Subject: Remove drivers/char/ChangeLog

The ChangeLog file under drivers/char is 30K of stuff dedicated to the
mid-90's TTY exploits of Ted Ts'o; it has been updated once since 1998
- and that was in 2001.  It's interesting history, but we don't
normally carry that kind of history inline with the code.  Let's remove
it.

-Sat Nov 22 07:53:36 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>

-	* serial.c, esp.c, rocket.c: Add tty->driver.break() routine, and
- 		allow high-level tty code to handle the break and soft
- 		carrier ioctls.
-	
-	* tty_ioctl.c (n_tty_ioctl): Support TIOCGSOFTCAR and

-
-	* serial.c (autoconfig): Change 16750 test to hopefully eliminate

-		detected as 16750, and other weird UARTs won't get poorly

-		the auto identification for the 16750.
-
-	* tty_io.c (tty_hangup): Now actually do the tty hangup
-		processing during the timer processing, and disable
-		interrupts while doing the hangup processing.  This avoids
-		several nasty race conditions which happened when the
-		hangup processing was done asynchronously.
-		(tty_ioctl): Do break handling in the tty driver if
-		driver's break function is supported.  
-		(tty_flip_buffer_push): New exported function which should
-		be used by drivers to push characters in the flip buffer
-		to the tty handler.  This may either be done using a task
-		queue function for better CPU efficiency, or directly for
-		low latency operation.
-
-	* serial.c (rs_set_termios): Fix bug rs_set_termios when
-		transitioning away from B0, submitted by Stanislav
-		Voronyi. 
-
-Thu Jun 19 20:05:58 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>
-
-	* serial.c (begin_break, end_break, rs_ioctl): Applied patch
-		to support BSD ioctls to set and clear the break
-		condition explicitly.
-
-	* console.c (scrup, scrdown, insert_line, delete_line): Applied
-		fix suggested by Aaron Tiensivu to speed up block scrolls
-		up and down.
-
-	* n_tty.c (opost_block, write_chan): Added a modified "fast
- 		console" patch which processes a block of text via
-		"cooking" efficiently.
-
-Wed Jun 18 15:25:50 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>
-
-	* tty_io.c (init_dev, release_dev): Applied fix suggested by Bill
-		Hawes to prevent race conditions in the tty code.
-
-	* n_tty.c (n_tty_chars_in_buffer): Applied fix suggested by Bill
-		Hawes so that n_tty_chars_in_buffer returns the correct
-		value in the case when the tty is in cannonical mode.  (To
-		avoid a pty deadlock with telnetd.)
-
-Thu Feb 27 01:53:08 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>
-
-	* serial.c (change_speed): Add support for the termios flag
-		CMSPAR, which allows the user to select stick parity.
-		(i.e, if PARODD is set, the parity bit is always 1; if
-		PARRODD is not set, then the parity bit is always 0).
-
-Wed Feb 26 19:03:10 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>
-
-	* serial.c (cleanup_module): Fix memory leak when using the serial
-		driver as a module; make sure tmp_buf gets freed!
-
-Tue Feb 25 11:01:59 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>
-
-	* serial.c (set_modem_info): Add support for setting and clearing
-		the OUT1 and OUT2 bits.  (For special case UART's, usually
-		for half-duplex.)
-		(autoconfig, change_speed): Fix TI 16750 support.
-
-Sun Feb 16 00:14:43 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>
-
-	* tty_io.c (release_dev): Add sanity check to make sure there are
-		no waiters on tty->read_wait or tty->write_wait.
-
-	* serial.c (rs_init): Don't autoconfig a device if the I/O region
-		is already reserved.
-
-	* serial.c (serial_proc_info): Add support for /proc/serial.
-
-Thu Feb 13 00:49:10 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>
-
-	* serial.c (receive_chars): When the UART repotrs an overrun
- 		condition, it does so with a valid character.  Changed to
- 		not throw away the valid character, but instead report the
-		overrun after the valid character.
-
-	* serial.c: Added new #ifdef's for some of the advanced serial
-		driver features.  A minimal driver that only supports COM
-		1/2/3/4 without sharing serial interrupts only takes 17k;
-		the full driver takes 32k.
-		
-Wed Feb 12 14:50:44 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>
-
-	* vt.c:
-	* pty.c: 
-	* tty_ioctl.c: 
-	* serial.c: Update routines to use the new 2.1 memory access
-	 	routines.
-
-Wed Dec  4 07:51:52 1996  Theodore Ts'o  <tytso@localhost.mit.edu>
-
-	* serial.c (change_speed): Use save_flags(); cli() and
-		restore_flags() in order to ensure we don't accidentally
-		turn on interrupts when starting up the port.
-		(startup): Move the insertion of serial structure into the
-		IRQ chain earlier into the startup processing.  Interrupts
-		should be off this whole time, but we eventually will want
-		to reduce this window.
-
-Thu Nov 21 10:05:22 1996  Theodore Ts'o  <tytso@localhost.mit.edu>
-
-	* tty_ioctl.c (tty_wait_until_sent): Always check the driver
- 		wait_until_ready routine, even if there are no characters
- 		in the xmit buffer.  (There may be charactes in the device
- 		FIFO.)
-		(n_tty_ioctl): Add new flag tty->flow_stopped which
- 		indicates whether the tty is stopped due to a request by
- 		the TCXONC ioctl (used by tcflow).  If so, don't let an
- 		incoming XOFF character restart the tty.  The tty can only
- 		be restarted by another TCXONC request.
-
-	* tty_io.c (start_tty): Don't allow the tty to be restarted if
-		tty->flow_stopped is true.
-
-	* n_tty.c (n_tty_receive_char): If tty->flow_stopped is true, and
- 		IXANY is set, don't eat a character trying to restart the
- 		tty.
-
-	* serial.c (startup): Remove need for MCR_noint from the
- 		async_struct structure.  Only turn on DTR and RTS if the
- 		baud rate is not zero.
-		(change_speed): More accurately calculate the timeout
- 		value based on the word size.  Move responsibility of
- 		hangup when speed becomes B0 to rs_set_termios()
-		(set_serial_info): When changing the UART type set the
- 		current xmit_fifo_size as well as the permanent
- 		xmit_fifo_size.
-		(rs_ioctl): Fix TCSBRK (used by tcdrain) and TCSBRKP
- 		ioctls to return EINTR if interrupted by a signal.
-		(rs_set_termios): If the baud rate changes to or from B0,
- 		this function is now responsible for setting or clearing
- 		DTR and RTS.  DTR and RTS are only be changed on the
- 		transition to or from the B0 state.
-		(rs_close): Wait for the characters to drain based on
- 		info->timeout.  At low baud rates (50 bps), it may take a
- 		long time for the FIFO to completely drain out!
-		(rs_wait_until_sent): Fixed timeout handling.  Now
- 		releases control to the scheduler, but checks frequently
- 		enough so that the function is sensitive enough to pass
- 		the timing requirements of the NIST-PCTS.
-		(block_til_ready): When opening the device, don't turn on
- 		DTR and RTS if the baud rate is B0.
-
-Thu Nov 14 00:06:09 1996  Theodore Ts'o  <tytso@rsts-11.mit.edu>
-
-	* serial.c (autoconfig): Fix autoconfiguration problems;
-		info->flags wasn't getting initialized from the state
-		structure.  Put in more paranoid test for the 16750.
-
-Fri Nov  8 20:19:50 1996  Theodore Ts'o  <tytso@rsts-11.mit.edu>
-
-	* n_tty.c (n_tty_flush_buffer): Only call driver->unthrottle() if
- 		the tty was previous throttled.
-		(n_tty_set_termios, write_chan): Add changes suggested by
- 			Simon P. Allen to allow hardware cooking.
-
-	* tty_ioctl.c (set_termios): If we get a signal while waiting for
-		the tty to drain, return -EINTR.
-	
-	* serial.c (change_speed): Add support for CREAD, as required by
-	 	POSIX.
-
-Sat Nov  2 20:43:10 1996  Theodore Ts'o  <tytso@rsts-11.mit.edu>
-
-	* serial.c: Wholesale changes.  Added support for the Startech
- 		16650 and 16650V2 chips.  (WARNING: the new startech
- 		16650A may or may not work!)  Added support for the
- 		TI16750 (not yet tested).  Split async_struct into a
- 		transient part (async_struct) and a permanent part
-		(serial_state) which contains the configuration
- 		information for the ports.  Added new driver routines
- 		wait_until_sent() and send_xchar() to help with POSIX
- 		compliance.  Added support for radio clocks which waggle
-		the carrier detect line (CONFIG_HARD_PPS).
-	
-	* tty_ioctl.c (tty_wait_until_sent): Added call to new driver
-		function tty->driver.wait_until_sent(), which returns when
-		the tty's device xmit buffers are drained.  Needed for
-		full POSIX compliance.
-
-		(send_prio_char): New function, called by the ioctl's
-		TCIOFF and TCION; uses the new driver call send_xchar(),
-		which will send the XON or XOFF character at high priority
-		(and even if tty output is stopped).
-
-Wed Jun  5 18:52:04 1996  Theodore Ts'o  <tytso@rsts-11.mit.edu>
-
-	* pty.c (pty_close): When closing a pty, make sure packet mode is
-	 	cleared.
-
-Sun May 26 09:33:52 1996  Theodore Ts'o  <tytso@rsts-11.mit.edu>
-
-	* vesa_blank.c (set_vesa_blanking): Add missing verify_area() call.
-
-	* selection.c (set_selection): Add missing verify_area() call.
-
-	* tty_io.c (tty_ioctl): Add missing verify_area() calls.
-
-	* serial.c (rs_ioctl): Add missing verify_area() calls.
-		(rs_init): Allow initialization of serial driver
-		configuration from a module.
-
-	* random.c (extract_entropy): Add missing verify_area call.
-		Don't limit number of characters returned to
-		32,768. Extract entropy is now no longer a inlined
-		function.
-
-		(random_read): Check return value in case extract_entropy
-		returns an error.
-
-		(secure_tcp_sequence_number): New function which returns a
-		secure TCP sequence number.  This is needed to prevent some
-		nasty TCP hijacking attacks.
-	
-		(init_std_data): Initialize using gettimeofday() instead of
-		struct timeval xtime.
-
-		(fast_add_entropy_word, add_entropy_word): Rename the
-		inline function add_entropy_word() to
-		fast_add_entropy_word().  Make add_entropy_word() be the
-		non-inlined function which is used in non-timing critical
-		places, in order to save space.
-
-		(initialize_benchmark, begin_benchmark, end_benchmark): New
-		functions defined when RANDOM_BENCHMARK is defined.  They
-		allow us to benchmark the speed of the
-		add_timer_randomness() call.
-
-		(int_ln, rotate_left): Add two new inline functions with
-		i386 optimized asm instructions.  This speeds up the
-		critical add_entropy_word() and add_timer_randomness()
-		functions, which are called from interrupt handlers.
-
-Tue May  7 22:51:11 1996    <tytso@rsts-11.mit.edu>
-
-	* random.c (add_timer_randomness): Limit the amount randomness
-		that we estimate to 12 bits.  (An arbitrary amount).
-
-		(extract_entropy): To make it harder to analyze the hash
-		function, fold the hash function in half using XOR, and
-		use the folded result as the value to emit to the user.
-		Also, add timer randomness each pass through the
-		exact_entropy call, to increase the amount of unknown
-		values during the extraction process.
-
-		(random_ioctl): Use IOR/IOW definitions to define the
-		ioctl values used by the /dev/random driver.  Allow the
-		old ioctl values to be used for backwards compatibility
-		(for a limited amount of time).
-
-Wed Apr 24 14:02:04 1996  Theodore Ts'o  <tytso@rsts-11.mit.edu>
-
-	* random.c (add_timer_randomness): Use 2nd derivative as well to
-		better estimate entropy.
-
-		(rand_initialize): Explicitly initialize all the pointers
-		to NULL.  (Clearing pointers using memset isn't portable.)
-		Initialize the random pool with OS-dependent data.
-
-		(random_write): Add sanity checking to the arguments to
-		random_write(), so that bad arguments won't cause a kernel
-		SEGV. 
-
-		(random_read): Update the access time of the device inode
-		when you return data to the user.
-
-		(random_ioctl): Wake up the random_wait channel when there
-		are only WAIT_INPUT_BITS available.  Add more paranoia
-		checks to make sure entropy_count doesn't go beyond the
-		bounds of (0, POOLSIZE).  Add a few missing verify_area
-		checks.  Add support for the RNDCLEARPOOL ioctl, which
-		zaps the random pool.
-
-		(add_timer_randomness): Wake up the random_wait
-		channel only when there are WAIT_INPUT_BITS available.
-
-		(random_select): Allow a random refresh daemon process to
-		select on /dev/random for writing; wake up the daemon when
-		there are less than WAIT_OUTPUT_BITS bits of randomness
-		available.
-
-Tue Apr 23 22:56:07 1996    <tytso@rsts-11.mit.edu>
-
-	* tty_io.c (init_dev): Change return code when user attempts to
-		open master pty which is already open from EAGAIN to EIO,
-		to match with BSD expectations.  EIO is more correct
-		anyway, since EAGAIN implies that retrying will be
-		successful --- which it might be.... Eventually!!
-
-	* pty.c (pty_open, pty_close): Fix wait loop so that we don't
-		busy loop while waiting for the master side to open.
-		Fix tty opening/closing logic.  TTY_SLAVE_CLOSED was
-		renamed to TTY_OTHER_CLOSED, so that the name is more
-		descriptive.  Also fixed code so that the tty flag
-		actually works correctly now....
-
-Mon Apr  1 10:22:01 1996    <tytso@rsts-11.mit.edu>
-
-	* serial.c (rs_close): Cleaned up modularization changes.
-		Remove code which forced line discipline back to N_TTY
-		this is done in the tty upper layers, and there's no
-		reason to do it here.  (Making this change also
-		removed the requirement that the serial module access
-		the internal kernel symbol "ldiscs".)
-
-	* tty_io.c (tty_init): Formally register a tty_driver entry for
-		/dev/tty (device 4, 0) and /dev/console (device 5, 0).
-		This guarantees that major device numbers 4 and 5 will be
-		reserved for the tty subsystem (as they have to be because
-		of /dev/tty and /dev/console).  Removed tty_regdev, as
-		this interface is no longer necessary.
-
-Sun Mar 17 20:42:47 GMT 1996 <ah@doc.ic.ac.uk>
-
-	* serial.c : modularisation (changes in linux/fs/device.c allow
-		kerneld to automatically load the serial module).
-
-	* Makefile, Config.in : serial modularisation adds.
-
-	* tty_io.c : tty_init_ctty used by to register "cua" driver just
-		for the /dev/tty device (5,0).  Added tty_regdev.
-	
-	* serial.c (shutdown, rs_ioctl) : when port shuts down wakeup processes
-	  waiting on delta_msr_wait. The TIOCMIWAIT ioctl returns EIO
-	  if no change was done since the time of call.
-
-Sat Mar 16 14:33:13 1996 <aeb@cwi.nl>
-
-	* tty_io.c (disassociate_ctty): If disassociate_ctty is called by
-		exit, do not perform an implicit vhangup on a pty.
-
-Fri Feb  9 14:15:47 1996    <tytso@rsts-11.mit.edu>
-
-	* serial.c (block_til_ready): Fixed another race condition which
-		happens if a hangup happens during the open.
-
-Wed Jan 10 10:08:00 1996    <tytso@rsts-11.mit.edu>
-
-	* serial.c (block_til_ready): Remove race condition which happened
-		if a hangup condition happened during the setup of the
-		UART, before rs_open() called block_til_ready().  This
-		caused the info->count counter to be erroneously
-		decremented.
-
-	* serial.c (startup, rs_open): Remove race condition that could
-		cause a memory leak of one page.  (Fortunately, both race
-		conditions were relatively rare in practice.)
-
-Tue Dec  5 13:21:27 1995    <tytso@rsts-11.mit.edu>
-
-	* serial.c (check_modem_status, rs_ioctl): Support the new
-		ioctl()'s TIOCGICOUNT, TIOCMIWAIT.  These allow an
-		application program to wait on a modem serial register
-		status bit change, and to find out how many changes have
-		taken place for the MSR bits.
-
-		(rs_write): Eliminate a race condition which is introduced
-		if it is necessary to wait for the semaphore.
-
-Sat Nov  4 17:14:45 1995    <tytso@rsts-11.mit.edu>
-
-	* tty_io.c (tty_init): Move registration of TTY_MAJOR and
-		TTY_AUX_MAJOR to the end, so that /proc/devices looks
-		prettier. 
-
-	* pty.c (pty_init): Use new major numbers for PTY master and slave
-		devices.  This allow us to have more than 64 pty's.  We
-		register the old pty devices for backwards compatibility.
-		Note that a system should either be using the old pty
-		devices or the new pty devices --- in general, it should
-		try to use both, since they map into the same pty table.
-		The old pty devices are strictly for backwards compatibility.
-
-Wed Oct 11 12:45:24 1995    <tytso@rsts-11.mit.edu>
-
-	* tty_io.c (disassociate_ctty): If disassociate_ctty is called by
-		exit, perform an implicit vhangup on the tty.
-
-	* pty.c (pty_close): When the master pty is closed, send a hangup
-		to the slave pty.
-		(pty_open): Use the flag TTY_SLAVE_CLOSED to test to see
-		if there are any open slave ptys, instead of using
-		tty->link->count.  The old method got confused if there
-		were processes that had hung-up file descriptors on the
-		slave tty.
-
-Tue May  2 00:53:25 1995    <tytso@rsx-11.mit.edu>
-
-	* tty_io.c (tty_set_ldisc): Wait until the output buffer is
-		drained before closing the old line discipline --- needed
-		in only one case: XON/XOFF processing.
-
-	* n_tty.c (n_tty_close): Don't bother waiting until the output
-		driver is closed; in general, the line discipline
-		shouldn't care if the hardware is finished
-		transmitting before the line discipline terminates.
-
-	* tty_io.c (release_dev): Shutdown the line discipline after
-		decrementing the tty count variable; but set the
-		TTY_CLOSING flag so that we know that this tty structure
-		isn't long for this world.
-
-	* tty_io.c (init_dev): Add sanity code to check to see if
-		TTY_CLOSING is set on a tty structure; if so, something
-		bad has happened (probably a line discipline close blocked
-		when it shouldn't have; so do a kernel printk and then
-		return an error).
-
-Wed Apr 26 10:23:44 1995  Theodore Y. Ts'o  <tytso@localhost>
-
-	* tty_io.c (release_dev): Try to shutdown the line discipline
-		*before* decrementing the tty count variable; this removes
-		a potential race condition which occurs when the line
-		discipline close blocks, and another process then tries
-		open the same serial port.
-
-	* serial.c (rs_hangup): When hanging up, flush the output buffer
-		before shutting down the UART.  Otherwise the line
-		discipline close blocks waiting for the characters to get
-		flushed, which never happens until the serial port gets reused.
-
-Wed Apr 12 08:06:16 1995  Theodore Y. Ts'o  <tytso@localhost>
-
-	* serial.c (do_serial_hangup, do_softint, check_modem_status,
-		rs_init):  Hangups are now scheduled via a separate tqueue
-		structure in the async_struct structure, tqueue_hangup.
-		This task is pushed on to the tq_schedule queue, so that
-		it is processed synchronously by the scheduler.
-
-Sat Feb 18 12:13:51 1995  Theodore Y. Ts'o  (tytso@rt-11)
-
-	* tty_io.c (disassociate_ctty, tty_open, tty_ioctl): Clear
-		current->tty_old_pgrp field when a session leader
-		acquires a controlling tty, and after a session leader
-		has disassociated from a controlling tty.
-
-Fri Feb 17 09:34:09 1995  Theodore Y. Ts'o  (tytso@rt-11)
-
-	* serial.c (rs_interrupt_single, rs_interrupt, rs_interrupt_multi): 
-		Change the number of passes made from 64 to be 256,
-		configurable with the #define RS_ISR_PASS_LIMIT.
-
-	* serial.c (rs_init, set_serial_info, get_serial_info, rs_close):
-		Remove support for closing_wait2.  Instead, set
-		tty->closing and rely on the line discipline to prevent
-		echo wars.
-
-	* n_tty.c (n_tty_receive_char):  IEXTEN does not need to be
-		enabled in order for IXANY to be active.
-
-		If tty->closing is set, then only process XON and XOFF
-                characters.
-
-Sun Feb 12 23:57:48 1995  Theodore Y. Ts'o  (tytso@rt-11)
-
-	* serial.c (rs_timer): Change the interrupt poll time from 60
-		seconds to 10 seconds, configurable with the #define
-		RS_STROBE_TIME.
-
-	* serial.c (rs_interrupt_multi, startup, shutdown, rs_ioctl,
-		set_multiport_struct, get_multiport_struct): Add
-		provisions for a new type of interrupt service routine,
-		which better supports multiple serial ports on a single
-		IRQ.  
-
-Sun Feb  5 19:35:11 1995  Theodore Y. Ts'o  (tytso@rt-11)
-
-	* tty_ioctl.c (n_tty_ioctl, set_termios, tty_wait_until_sent): 
-	* serial.c (rs_ioctl, rs_close): 
-	* cyclades.c (cy_ioctl, cy_close): 
-	* n_tty.c (n_tty_close):  Rename wait_until_sent to
-		tty_wait_until_sent, so that it's a better name to export
-		in ksyms.c.
-
-Sat Feb  4 23:36:20 1995  Theodore Y. Ts'o  (tytso@rt-11)
-
-	* serial.c (rs_close): Added missing check for closing_wait2 being
-		ASYNC_CLOSING_WAIT_NONE.
-
-Thu Jan 26 09:02:49 1995  Theodore Y. Ts'o  (tytso@rt-11)
-
-	* serial.c (rs_init, set_serial_info, get_serial_info,
-		rs_close): Support close_wait in the serial driver.
-		This is helpful for slow devices (like serial
-		plotters) so that their outputs don't get flushed upon
-		device close.  This has to be configurable because
-		normally we don't want ports to be hung up for long
-		periods of time during a close when they are not
-		connected to a device, or the device is powered off.
-
-		The default is to wait 30 seconds; in the case of a
-		very slow device, the close_wait timeout should be
-		lengthened.  If it is set to 0, the kernel will wait
-		forever for all of the data to be transmitted.
-
-Thu Jan 17 01:17:20 1995  Theodore Y. Ts'o  (tytso@rt-11)
-
-	* serial.c (startup, change_speed, rs_init): Add support to detect
-		the StarTech 16650 chip.  Treat it as a 16450 for now,
-		because of its FIFO bugs.
-
-Thu Jan  5 21:21:57 1995  <dahinds@users.sourceforge.net>
-
-	* serial.c: (receive_char): Added counter to prevent infinite loop
-		when a PCMCIA serial device is ejected.
-
-Thu Dec 29 17:53:48 1994    <tytso@rsx-11.mit.edu>
-
-	* tty_io.c (check_tty_count): New procedure which checks
-		tty->count to make sure that it matches with the number of
-		open file descriptors which point at the structure.  If
-		the number doesn't match, it prints a warning message.
-
-Wed Dec 28 15:41:51 1994    <tytso@rsx-11.mit.edu>
-
-	* tty_io.c (do_tty_hangup, disassociate_ctty): At hangup time,
-		save the tty's current foreground process group in the
-		session leader's task structure.  When the session leader
-		terminates, send a SIGHUP, SIGCONT to that process group.
-		This is not required by POSIX, but it's not prohibited
-		either, and it appears to be the least intrusive way
-		to fix a problem that dialup servers have with
-		orphaned process groups caused by modem hangups.

-	* serial.c (rs_ioctl): Don't allow most ioctl's if the serial port
-		isn't initialized.
-
-	* serial.c (rs_close): Don't clear the IER if the serial port
-		isn't initialized. 
-
-	* serial.c (block_til_ready): Don't try to block on the dialin
-		port if the serial port isn't initialized.
-
-Wed Dec  7 10:48:30 1994  Si Park (si@wimpol.demon.co.uk)
-	* tty_io.c (tty_register_driver): Fix bug when linking onto
-		the tty_drivers list. We now test that there are elements
-		already on the list before setting the back link from the
-		first element to the new driver.
-
-	* tty_io.c (tty_unregister_driver): Fix bug in unlinking the
-		specified driver from the tty_drivers list. We were not
-		setting the back link correctly. This used to result in
-		a dangling back link pointer and cause panics on the next
-		call to get_tty_driver().
-
-Tue Nov 29 10:21:09 1994  Theodore Y. Ts'o  (tytso@rt-11)
-
-	* tty_io.c (tty_unregister_driver): Fix bug in
-		tty_unregister_driver where the pointer to the refcount is
-		tested, instead of the refcount itself.  This caused
-		tty_unregister_driver to always return EBUSY.
-
-Sat Nov 26 11:59:24 1994  Theodore Y. Ts'o  (tytso@rt-11)
-
-	* tty_io.c (tty_ioctl): Add support for the new ioctl
-		TIOCTTYGSTRUCT, which allow a kernel debugging program
-		direct read access to the tty and tty_driver structures.
-
-Fri Nov 25 17:26:22 1994  Theodore Y. Ts'o  (tytso@rt-11)
-
-	* serial.c (rs_set_termios): Don't wake up processes blocked in
-		open when the CLOCAL flag changes, since a blocking
-		open only samples the CLOCAL flag once when it blocks,
-		and doesn't check it again.  (n.b.  FreeBSD has a
-		different behavior for blocking opens; it's not clear
-		whether Linux or FreeBSD's interpretation is correct.
-		POSIX doesn't give clear guidance on this issue, so
-		this may change in the future....)
-
-	* serial.c (block_til_ready): Use the correct termios structure to
-		check the CLOCAL flag.  If the cuaXX device is active,
-		then check the saved termios for the ttySXX device.
-		Otherwise, use the currently active termios structure.
-
-Sun Nov  6 21:05:44 1994  Theodore Y. Ts'o  (tytso@rt-11)
-
-	* serial.c (change_speed): Add support for direct access of
-		57,600 and 115,200 bps.
-
-Wed Nov  2 10:32:36 1994  Theodore Y. Ts'o  (tytso@rt-11)
-
-	* n_tty.c (n_tty_receive_room): Only allow excess characters
-		through if we are in ICANON mode *and* there are other no
-		pending lines in the buffer.  Otherwise cut and paste over
-		4k breaks.
-
-Sat Oct 29 18:17:34 1994  Theodore Y. Ts'o  (tytso@rt-11)
-
-	* serial.c (rs_ioctl, get_lsr_info): Added patch suggested by Arne
-		Riiber so that user mode programs can tell when the
-		transmitter shift register is empty.
-
-Thu Oct 27 23:14:29 1994  Theodore Y. Ts'o  (tytso@rt-11)
-
-	* tty_ioctl.c (wait_until_sent): Added debugging printk statements
-		(under the #ifdef TTY_DEBUG_WAIT_UNTIL_SENT)  
-
-	* serial.c (rs_interrupt, rs_interrupt_single, receive_chars,
-		change_speed, rs_close): rs_close now disables receiver
-		interrupts when closing the serial port.  This allows the
-		serial port to close quickly when Linux and a modem (or a
-		mouse) are engaged in an echo war; when closing the serial
-		port, we now first stop listening to incoming characters,
-		and *then* wait for the transmit buffer to drain.  
-
-		In order to make this change, the info->read_status_mask
-		is now used to control what bits of the line status
-		register are looked at in the interrupt routine in all
-		cases; previously it was only used in receive_chars to
-		select a few of the status bits.
-
-Mon Oct 24 23:36:21 1994  Theodore Y. Ts'o  (tytso@rt-11)
-
-	* serial.c (rs_close): Add a timeout to the transmitter flush
-		loop; this is just a sanity check in case we have flaky
-		(or non-existent-but-configured-by-the-user) hardware.
-
-Fri Oct 21 09:37:23 1994  Theodore Y. Ts'o  (tytso@rt-11)
-
-	* tty_io.c (tty_fasync): When asynchronous I/O is enabled, if the
-		process or process group has not be specified yet, set it
-		to be the tty's process group, or if that is not yet set,
-		to the current process's pid.
-
-Thu Oct 20 23:17:28 1994  Theodore Y. Ts'o  (tytso@rt-11)
-
-	* n_tty.c (n_tty_receive_room): If we are doing input
-		canonicalization, let as many characters through as
-		possible, so that the excess characters can be "beeped".
-
-Tue Oct 18 10:02:43 1994  Theodore Y. Ts'o  (tytso@rt-11)
-
-	* serial.c (rs_start): Removed an incorrect '!' that was
-		preventing transmit interrupts from being re-enabled in
-		rs_start().  Fortunately in most cases it would be
-		re-enabled elsewhere, but this still should be fixed
-		correctly.
-
-Sun Oct  9 23:46:03 1994  Theodore Y. Ts'o  (tytso@rt-11)
-
-	* tty_io.c (do_tty_hangup): If the tty driver flags
-		TTY_DRIVER_RESET_TERMIOS is set, then reset the termios
-		settings back to the driver's initial configuration.  This
-		allows the termios settings to be reset even if a process
-		has hung up file descriptors keeping a pty's termios from
-		being freed and reset.
-
-	* tty_io.c (release_dev): Fix memory leak.  The pty's other
-		termios structure should also be freed.
-
-	* serial.c (rs_close, shutdown): Change how we wait for the
-		transmitter to completely drain before shutting down the
-		serial port.  We now do it by scheduling in another
-		process instead of busy looping with the interrupts turned
-		on.  This may eliminate some race condition problems that
-		some people seem to be reporting.
-
-Sun Sep 25 14:18:14 1994  Theodore Y. Ts'o  (tytso@rt-11)
-
-	* tty_io.c (release_dev): When freeing a tty make sure that both
-		the tty and the o_tty (if present) aren't a process's
-		controlling tty.  (Previously, we only checked the tty.)
-
-	* serial.c (change_speed): Only enable the Modem Status
-		Interrupt for a port if CLOCAL is not set or CRTSCTS
-		is set.  If we're not checking the carrier detect and
-		CTS line, there's no point in enabling the modem
-		status interrupt.  This will save spurious interrupts
-		from slowing down systems who have terminals that
-		don't support either line.  (Of course, if you want
-		only one of CD and CTS support, you will need a
-		properly wired serial cable.)
-
-Thu Sep 22 08:32:48 1994  Theodore Y. Ts'o  (tytso@rt-11)
-
-	* tty_io.c (do_SAK): Return if tty is null.
-
-	* tty_io.c (_tty_name): Return "NULL tty" if the passed in tty is
-		NULL.
-
-Sat Sep 17 13:19:25 1994  Theodore Y. Ts'o  (tytso@rt-11)
-
-	* tty_ioctl.c (n_tty_ioctl): Fix TIOCGLCKTRMIOS and
-		TIOCSLCKTRMIOS, which were totally broken.  Remove
-		extra indirection from argument; it should be a struct
-		termios *, not a struct termios **.
-		&real_tty->termios_locked should have been
-		real_tty->termios_locked.  This caused us to be
-		reading and writing the termios_locked structure to
-		random places in kernel memory.  
-
-	* tty_io.c (release_dev): Oops!  Forgot to delete a critical kfree
-		of the locked_termios.  This leaves the locked_termios
-		structure pointed at a freed object.  
-
-Fri Sep 16 08:13:25 1994  Theodore Y. Ts'o  (tytso@rt-11)
-
-	* tty_io.c (tty_open): Don't check for an exclusive open until
-		after the device specific open routine has been called.
-		Otherwise, the serial device ref counting will be screwed
-		up.
-
-	* serial.c (rs_open, block_til_ready): Don't set termios structure
-		until after block_til_ready has returned successfully.
-		Modify block_til_ready to check the normal_termios
-		structure directly, so it doesn't rely on termios being
-		set before it's called.
-
-Thu Sep 15 23:34:01 1994  Theodore Y. Ts'o  (tytso@rt-11)
-
-	* serial.c (rs_close): Turn off interrupts during rs_close() to
-		prevent a race condition with the hangup code (which
-		runs during a software interrupt).
-
-	* tty_io.c (release_dev): Don't free the locked_termios structure;
-		its state must be retained across device opens.
-
-
-	* tty_io.c (tty_unregister_driver): Added function to unregister a
-		tty driver.  (For loadable device drivers.)

-2001-05-10  Fred Barnes  <frmb2@ukc.ac.uk>
-
-       * parport_pc.c (parport_pc_epp_read_data): added support for

-
-2001-05-07  Fred Barnes  <frmb2@ukc.ac.uk>

-	parport_pc_epp_write_addr): support for fast reads/writes using
-	the PARPORT_EPP_FAST flag.
- 
- 	* ieee1284.c (parport_read, parport_write): added code to handle
-	software EPP mode (IEEE1284_MODE_EPPSWE).  Added code to allow

-	mode).
- 
- 	* ieee1284_ops.c (parport_ieee1284_epp_read_data,
-	parport_ieee1284_epp_write_data): fixed various polarity problems.
-	Also (theoretically) fixed address versions (.._addr), but no
-	hardware to test this on.
- 
- 	* parport_pc.h: added parport_dump_state() function for debugging.
- 	Needs to have DEBUG_PARPORT to be defined for it to be included.
- 
-2001-05-03  Tim Waugh  <twaugh@redhat.com>
-
-	* parport_pc.c: Fix the compile problem I introduce from the last
-	change.
-
-2001-04-20  Paul Gortmaker  <p_gortmaker@yahoo.com>
-
-	* parport_pc.c: Cut down the size quite a bit (more than 4k off

Subject: xen: Remove unnecessary arch specific xen irq functions.

Right now xen's use of the x86 and ia64 handle_irq is just bizarre and very
fragile as it is very non-obvious the function exists and is is used by
code out in drivers/....  Luckily using handle_irq is completely unnecessary,
and we can just use the generic irq apis instead.

This still leaves drivers/xen/events.c as a problematic user of the generic
irq apis it has "static struct irq_info irq_info[NR_IRQS]" but that can be
fixed some other time.

Subject: RDMA/nes: Fix crash when listener destroyed during loopback setup

When a listener is destroyed and there is an MPA response pending for
loopback connection, the active side cm_node gets destroyed twice:
once in cm_event_connect_error() and again in nes_accept()/nes_reject().

Increment the cm_node's refcount so it's not destroyed by
cm_event_connect_error().

Subject: firewire: ohci: work around cycle timer bugs on VIA controllers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

VIA controllers sometimes return an inconsistent value when reading the
isochronous cycle timer register.  To work around this, read the
register multiple times and add consistency checks.

Subject: firewire: get_cycle_timer optimization and cleanup

ohci:  Break out of the retry loop if too many attempts were necessary.
This may theoretically happen if the chip is fatally defective or if the
get_cycle_timer ioctl was performed after a CardBus controller was
ejected.

Also micro-optimize the loop by re-using the last two register reads in
the next iteration, remove a questionable inline keyword, and shuffle a
comment around.

core:  ioctl_get_cycle_timer() is always called with interrupts on,
therefore local_irq_save() can be replaced by local_irq_disable().
Disabled local IRQs imply disabled preemption, hence preempt_disable()
can be removed.

Subject: firewire: remove incomplete Bus_Time CSR support
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The current implementation of Bus_Time read access was buggy since it
did not ensure that Bus_Time.second_count_hi and second_count_lo came
from the same 128 seconds period.

Reported-by: HÃ¥kan Johansson <f96hajo@chalmers.se>

Instead of a fix, remove Bus_Time register support altogether.  The spec
requires all cycle master capable nodes to implement this (all Linux
nodes are cycle master capable) while it also says that it "may" be
initialized by the bus manager or by the IRM standing in for a bus
manager.  (Neither Linux' firewire-core nor ieee1394 nodemgr implement
this.)

Since we cannot rely on Bus_Time having been initialized by a bus
manager, it is better to return an error instead of a nonsensical value
on a read request to Bus_Time.

Alternatively, we could fix the Bus_Time read integrity bug _and_
implement (a) cycle master's write support of the register as well as
(b) bus manager's Bus_Time initialization service, i.e. preservation of
the Bus_Time when the cycle master node of a bus changes.  However, that
would be quite some code for a feature that is unreliable to begin with
and very likely unused in practice.

Subject: drm/i915: enable memory self refresh on 9xx

Enabling memory self refresh (SR) on 9xx needs to set additional
register bits. On 945, we need bit 31 of FW_BLC_SELF to enable the
write to self refresh bit and bit 16 to enable the write of self
refresh watermark. On 915, bit 12 of INSTPM is used to enable SR.

SR will take effect when CPU enters C3+ state and its entry/exit
should be automatically controlled by H/W, driver only needs to set
SR enable bits in wm update. But this isn't safe in my test on 945
because GPU is hung. So this patch explicitly enables SR when GPU
is idle, and disables SR when it is busy. In my test on a netbook of
945GSE chipset, it saves about 0.8W idle power.

Subject: drm/i915: add dynamic performance control support for Ironlake

Ironlake (and 965GM, which this patch doesn't support) supports a
hardware performance and power management feature that allows it to
adjust to changes in GPU load over time with software help.  The goal
if this is to maximize performance/power for a given workload.

This patch enables that feature, which is also a requirement for
supporting Intelligent Power Sharing, a feature which allows for
dynamic budgeting of power between the CPU and GPU in Arrandale
platforms.

Subject: drm/i915: Fix OGLC performance regression on 945

He Shuang reported an OGLC performance regression introduced in the patch
"enable memory self refresh on 9xx", In that patch, SR on 945 is disabled
everytime when calling intel_mark_busy(), while too much of such operation
will impact performance. Actually disable SR is necessary only when GPU and
Crtc changing from idle to busy. This patch make such optimization.

It fixes upstream bug
http://bugs.freedesktop.org/show_bug.cgi?id=26422

Subject: drm/i915: fix drps disable so unload & re-load works

At unload time, we need to disable DRPS, but we need to do it correctly
or the GPU will hang and we won't be able to load the module again.  So
set the SFCAVM bit so we can properly restore the DRPS config at unload.

No functional change, because gtt flushing is a no-op. Still, try
to keep the bookkeeping accurate. The if is still slightly wrong
for with execbuf2 even i915-class hw doesn't always need a fence
reg for gpu access. But that's for somewhen lateron.

Subject: drm/i915: blow away userspace mappings before fence change

This aligns it with the other user of i915_gem_clear_fence_reg,
which blows away the mapping before changing the fence reg.

Only affects userspace if it races against itself when changing
tiling parameters, i.e. behaviour is undefined, anyway.

Subject: drm/i915: reduce some of the duplication of tiling checking

i915_gem_object_fenceable was mostly just a repeat of the
i915_gem_object_fence_offset_ok, but also checking the size (which was
checkecd when we allowed that BO to be tiled in the first place). So
instead, export the latter function and use it in place.

deal with lid open/close, when we might need to reset the mode.

Subject: drm/i915: Record batch buffer following GPU error

In order to improve our diagnostic capabilities following a GPU hang
and subsequent reset, we need to record the batch buffer that triggered
the error. We assume that the current batch buffer, plus a few details
about what else is on the active list, will be sufficient -- at the very
least an improvement over nothing.

The extra information is stored in /debug/dri/.../i915_error_state
following an error, and may be decoded using
intel_gpu_tools/tools/intel_error_decode.

v2: Avoid excessive work under spinlocks.
v3: Include ringbuffer for later analysis.
v4: Use kunmap correctly and record more buffer state.
v5: Search ringbuffer for current batch buffer
v6: Use a work fn for the impossible IRQ error case.
v7: Avoid non-atomic paths whilst in IRQ context.

Subject: drm: Add generic multipart buffer.

Allocating multiple pages of memory for data that is coming
from user space may fail. To fix memory allocation failures
the buffer object should be split to multiple independ pages.

drm buffer provides generic interface to copy and process
large data arrays from user space.

Interface includes allocation and free functions to allocate
the buffer object and data storage pages.

All access operations are performed relative to a internal
pointer which is advanced with drm_buffer_advance function.

The buffer can be accessed using drm_buffer_pointer_to_XXX
functions if it is known that requested object doesn't split
over a page boundary. These functions don't do any error
checking to maximize performance.

If there is large object which could be split there is special
drm_buffer_read_object function. drm_buffer_read_object takes
a pointer as argument which is used as temporary store for
data if it is split over boundary in the buffer.

From: Pauli Nieminen <suokkos@gmail.com>
Date: Mon, 1 Feb 2010 19:11:16 +0200
Subject: drm/radeon: Fix memory allocation failures in the preKMS command
 stream checking.

Allocation of single large block of memory may fail under memory
presure. drm_buffer object can hold one large block of data in
multiple independ pages which preents alloation failures.

This patch converts all access to command stream to use drm_buffer
interface. All direct access to array has to go tough drm_buffer
functions to get correct pointer.

Outputting the command stream to ring buffer needs to be awear of
the split nature of drm_buffer. The output operation requires the
new OUT_RING_DRM_BUFFER.

Subject: [rfc] drm/radeon/kms: pm debugging check for vbl.

This patch adds a check on avivo chips to see if we are in the VBL
region for the active crtcs when we trigger the engine change.

I appear to have glitches locally on pm transistion (not sure all
fixes are in yet) and this at least seems to be correct here,
maybe others can test on systems with no glitches.

Subject: drm/radeon/kms: simplify storing current and requested PM mode
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We kept pointers to requested and current clock modes in every power state.
That was useless, more /global/ pointers in power struct are enough.

Subject: ACPI thermal: Don't invalidate thermal zone if critical trip point is
 bad

V2: Corrected integer/long conversion.

Some BIOSes return a negative value for the critical trip point.
Especially since Windows 2006...
We currently invalidate the whole thermal zone in this case.
But it may still be needed for cooling, also without critical
trip point.

This patch invalidates the critical trip point if no _CRT
function is found or if it returns negative values, but does
not invalidate the whole thermal zone in this case.

From bcc60c381d857ced653e912cbe6121294773e147 Mon Sep 17 00:00:00 2001
From: Or Gerlitz <ogerlitz@voltaire.com>
Date: Mon, 8 Feb 2010 13:17:42 +0000
Subject: IB/iser: New receive buffer posting logic

Currently, the recv buffer posting logic is based on the transactional
nature of iSER which allows for posting a buffer before sending a PDU.
Change this to post only when the number of outstanding recv buffers
is below a water mark and in a batched manner, thus simplifying and
optimizing the data path.  Use a pre-allocated ring of recv buffers
instead of allocating from kmem cache.  A special treatment is given
to the login response buffer whose size must be 8K unlike the size of
buffers used for any other purpose which is 128 bytes.

Subject: IB/iser: Use different CQ for send completions

Use a different CQ for send completions, where send completions are
polled by the interrupt-driven receive completion handler.  Therefore,
interrupts aren't used for the send CQ.

Subject: IB/iser: Simplify send flow/descriptors

Simplify and shrink the logic/code used for the send descriptors.
Changes include removing struct iser_dto (an unnecessary abstraction),
using struct iser_regd_buf only for handling SCSI commands, using
dma_sync instead of dma_map/unmap, etc.

Subject: IB/iser: Use atomic allocations

Two minor flows in iSER's data path still use allocations; move them
to be atomic as a preperation step towards moving to use libiscsi
passthrough mode.

Subject: IB/iser: Remove unnecessary connection checks

Remove unnecessary checks for the IB connection state and for QP
overflow, as conn state changes are reported by iSER to libiscsi and
handled there. QP overflow is theoretically possible only when
unsolicited data-outs are used; anyway it's being checked and handled
by HW drivers.

Subject: IB/iser: Use libiscsi passthrough mode

libiscsi passthrough mode invokes the transport xmit calls directly
without first going through an internal queue, unlike the other mode,
which uses a queue and a xmitworker thread.  Now that the "cant_sleep"
prerequisite of iscsi_host_alloc is met, move to use it.  Handling
xmit errors is now done by the passthrough flow of libiscsi.  Since
the queue/worker aren't used in this mode, the code that schedules the
xmitworker is removed.

Subject: IB/iser: Remove redundant locking from iser scsi command response
 flow

Currently the iSER receive completion flow takes the session lock
twice.  Optimize it to avoid the first one by letting
iser_task_rdma_finalize() be called only from the cleanup_task
callback invoked by iscsi_free_task, thus reducing the contention on
the session lock between the scsi command submission to the scsi
command completion flows.

Subject: IB/uverbs: Convert *cdev to cdev in struct ib_uverbs_device

Instead of storing a pointer to a cdev, embed the entire struct cdev.

This change allows us to use the container_of() macro in
ib_uverbs_open() in a future patch.

This change increases the size of struct ib_uverbs_device to 168 bytes
across 3 cachelines from 80 bytes in 2 cachelines.  However, we
rearrange the members so that everything fits into the first cacheline
except for the struct cdev. Finally, we don't touch the cdev in any
fastpaths, so this change shouldn't negatively affect performance.

Subject: IB/uverbs: Remove dev_table

dev_table's raison d'etre was to associate an inode back to a struct
ib_uverbs_device.

However, now that we've converted ib_uverbs_device to contain an
embedded cdev (instead of a *cdev), we can use the container_of()
macro and cast back to the containing device.

There's no longer any need for dev_table, so get rid of it.

Subject: IB/uverbs: Increase maximum devices supported

Some large systems may support more than IB_UVERBS_MAX_DEVICES
(currently 32).

This change allows us to support more devices in a backwards-compatible
manner.  The first IB_UVERBS_MAX_DEVICES keep the same major/minor
device numbers that they've always had.

If there are more than IB_UVERBS_MAX_DEVICES, we then dynamically
request a new major device number (new minors start at 0).

This change increases the maximum number of HCAs to 64 (from 32).

Subject: IB/umad: Convert *cdev to cdev in struct ib_umad_port

Instead of storing pointers to cdev and sm_cdev, embed the full
structures instead.

This change allows us to use the container_of() macro in ib_umad_open()
and ib_umad_sm_open() in a future patch.

This change increases the size of struct ib_umad_port to 320 bytes
from 128.

Subject: IB/umad: Remove port_table[]

We no longer need this data structure, as it was used to associate an
inode back to a struct ib_umad_port during ->open().  But now that
we're embedding a struct cdev in struct ib_umad_port, we can use the
container_of() macro to go from the inode back to the device instead.

Subject: IB/umad: Increase maximum devices supported

Some large systems may support more than IB_UMAD_MAX_PORTS
(currently 64).

This change allows us to support more ports in a backwards-compatible
manner.  The first IB_UMAD_MAX_PORTS keep the same major/minor device
numbers they've always had.

If there are more than IB_UMAD_MAX_PORTS, we then dynamically request
a new major device number (new minors start at 0).

Subject: IB/ucm: Use stack variable 'devnum' in ib_ucm_add_one

This change is not useful by itself, but sets us up for a future
change that allows us to dynamically allocate device numbers in case
we have more than IB_UCM_MAX_DEVICES in the system.

Subject: IB/ucm: Increase maximum devices supported

Some large systems may support more than IB_UCM_MAX_DEVICES
(currently 32).

This change allows us to support more devices in a backwards-compatible
manner. the first IB_UCM_MAX_DEVICES keep the same major/minor device
numbers they've always had.

If there are more than IB_UCM_MAX_DEVICES, then we dynamically request
a new major device number (new minors start at 0).

Subject: RDMA/cxgb3: Doorbell overflow avoidance and recovery

T3 hardware doorbell FIFO overflows can cause application stalls due
to lost doorbell ring events.  This has been seen when running large
NP IMB alltoall MPI jobs.  The T3 hardware supports an xon/xoff-type
flow control mechanism to help avoid overflowing the HW doorbell FIFO.

This patch uses these interrupts to disable RDMA QP doorbell rings
when we near an overflow condition, and then turn them back on (and
ring all the active QP doorbells) when when the doorbell FIFO empties
out.  In addition if an doorbell ring is dropped by the hardware, the
code will now recover.

Design:

cxgb3:
- enable these DB interrupts
- in the interrupt handler, schedule work tasks to call the ULPs event
  handlers with the new events.
- ring all the qset txqs when an overflow is detected.

iw_cxgb3:
- disable db ringing on all active qps when we get the DB_FULL event
- enable db ringing on all active qps and ring all active dbs when we get
  the DB_EMPTY event
- On DB_DROP event:
       - disable db rings in the event handler
       - delay-schedule a work task which rings and enables the dbs on
         all active qps.
- in post_send and post_recv logic, don't ring the db if it's disabled.

Subject: RDMA/cxgb3: Mark RDMA device with CXIO_ERROR_FATAL when removing

If cxgb3 calls the iw_cxgb3 t3cclient remove function due to a device
removal event, then the iwch device must be marked with CXIO_ERROR_FATAL
since the device below us is going away.  Otherwise, we can get stuck in
a deadlock as RDMA ULPs try and deallocate objects (like MRs, QPs, etc).
So always mark the device with CXIO_ERROR_FATAL when removing.

Subject: firewire: core: fix "giving up on config rom" with Panasonic
 AG-DV2500

The Panasonic AG-DV2500 tape deck contains an invalid entry in its
configuration ROM root directory:  A leaf pointer with the undefined key
ID 0 and an offset that points way out of the standard config ROM area.
This caused firewire-core to dismiss the device with the generic log
message "giving up on config rom for node id...", after which it was of
course impossible to access the tape deck with dvgrab or any other
program.  https://bugzilla.redhat.com/show_bug.cgi?id=449252#c29

The fix is to simply ignore this invalid ROM entry and proceed to read
the valid rest of the ROM.  There is a catch though:  When the kernel
later iterates over the ROM, it would be nasty having to check again for
such too large ROM offsets.  Therefore we manipulate the defective or
unsupported ROM entry to become a harmless immediate entry that won't
have any side effects later (an entry with the value 0x00000000).

Subject: firewire: core: don't fail device creation in case of too large
 config ROM blocks

It never happened yet, but better safe than sorry:  If a device's config
ROM contains a block which overlaps the boundary at 0xfffff00007ff, just
ignore that one block instead of refusing to add the device
representation.  That way, upper layers (kernelspace or userspace
drivers) might still be able to use the device to some degree.

That's better than total inaccessibility of the device.  Worse, the core
would have logged only a generic "giving up on config rom" message which
could only be debugged by feeding a firewire-ohci debug logging session
through a config ROM interpreter, IOW would likely remain undiagnosed.

Subject: firewire: core: increase stack size of config ROM reader

The stack size of 16 was artificially chosen and may be too small in
extreme cases.  A device won't be accessible then.

Since it doesn't really matter to the slab allocator whether we ask for
1088 bytes or 2048 bytes of scratch memory, just allocate 2048 bytes for
the sum of temporary config ROM image and stack, and we will never ever
overflow the stack (because there simply can't be more stack items than
ROM entries).

Subject: firewire: core: fix an information leak

If a device exposes a sparsely populated configuration ROM,
firewire-core's sysfs interface and character device file interface
showed random data in the gaps between config ROM blocks.  Fix this by
zero-initialization of the config ROM reader's scratch buffer.

Subject: firewire: cdev: add more flexible cycle timer ioctl

The system time from CLOCK_REALTIME is not monotonic, hence problematic
for the main user of the FW_CDEV_IOC_GET_CYCLE_TIMER ioctl.  This issue
exists in its successor ABI, i.e. raw1394, too.
http://subversion.ffado.org/ticket/242

We now offer an alternative ioctl which lets the caller choose between
CLOCK_REALTIME, CLOCK_MONOTONIC, and CLOCK_MONOTONIC_RAW as source of
the local time, very similar to the clock_gettime libc function.  The
format of the local time return value matches that of clock_gettime
(seconds and nanoseconds, instead of a single microseconds value from
the existing ioctl).

Subject: firewire: core: change type of a data buffer

from array of char to union of structs.  I already used a union to size
the buffer which holds ioctl arguments; more consequent is to define it
as an instance of this union in the first place.

Also rename several local variables from "request" to "a"(rgument) since
the term request can be mistaken to mean a transaction subaction, e.g.
an instance of struct fw_request.

Subject: firewire: ohci: remove unused dualbuffer IR code

This code was no longer used since 2.6.33, "firewire: ohci: always use
packet-per-buffer mode for isochronous reception" commit 090699c0.  If
anybody needs this code in the future for special purposes, it can be
brought back in.  But it must not be re-enabled by default; drivers
(kernelspace or userspace drivers) should only get this mode if they
explicitly request it.

Subject: firewire: ohci: reorder struct fw_ohci for better cache efficiency

The config_rom struct members are only accessed during relatively
infrequent self-ID-complete interrupts and only if the local config ROM
was changed, while the ar_, at_, ir_, it_ members are used very
frequently during I/O.  Hence move the config_rom members further down.

More importantly, make the huge self_id_buffer member the last one; this
is only accessed in self-ID-complete interrupts.

Subject: firewire: ohci: use an ID table for quirks detection

We don't have a lot of quirks to take into account (especially since
dual-buffer IR is out of the picture), but still, a table-based approach
is more organized than a series of if () clauses.

Subject: firewire: ohci: add module parameter to activate quirk fixes

This way, we can advise users of precompiled kernel packages to test
existing quirk fixes on chips which have not been listed yet, without
them having to build a kernel from source.

Note, to use this feature on a machine with more than one controller,
steps like these are necessary:
# lspci | grep 1394
# ls /sys/bus/pci/drivers/firewire_ohci/
# echo -n "0000:03:02.0" > /sys/bus/pci/drivers/firewire_ohci/unbind
# echo 2 > /sys/module/firewire_ohci/parameters/quirks
# echo -n "0000:03:02.0" > /sys/bus/pci/drivers/firewire_ohci/bind
# echo 0 > /sys/module/firewire_ohci/parameters/quirks

The parameter can also be used to switch off quirk flags that were
hardwired into firewire-ohci's quirks table.  Simply specify a non-zero
quirks value but without any known flags, e.g. 0x100.

Subject: firewire: ohci: fix IR/IT context mask mixup

This bug was present in firewire-ohci since day one:  The number of
available isochronous receive DMA contexts was mixed up with that of
available isochronous transmit DMA contexts.

This is harmless on a few chips which offer the same number of contexts
in both directions, but most chips nowadays implement only the standard
minimum of 4 IR contexts, but 8 IT contexts.  If a user attempted to run
a lot of IR contexts at once, results with more than four were therefore
unpredictable.  I suppose the controller would simply refuse to start
DMA of any unimplemented context.

Subject: IB/core: Fix and clean up ib_ud_header_init()

ib_ud_header_init() first clears header and then fills up the various
fields.  Later on, it tests header->immediate_present, which it has
already cleared, so the condition is always false.  Fix this by adding
an immediate_present parameter and setting header->immediate_present
as is done with grh_present.  Also remove unused calculation of
header_len.

Subject: IB/uverbs: Use anon_inodes instead of private infinibandeventfs

The anon_inodes interface has been split to allow creating a bare
(non-installed) file pointer and also extended to allow specifying
O_RDONLY in the flags.  This makes it a suitable replacement for the
private "infinibandeventfs" pseudo-filesystem used by uverbs, and this
replacement saves a small chunk of boilerplate code.

This patch properly set visible VRAM and enforce any pinned buffer
to be into visible VRAM. We might later add a flag to release this
constraint for some newer hw more clever than previous.

From 383be5d1789d9a7a2e77dca1cb0aca89507d069e Mon Sep 17 00:00:00 2001

Subject: drm/radeon/kms: update new pll algo

- add support for pre-avivo chips
- add support for fixed post/ref dividers
- add support for non-fractional fb dividers

By default avivo chips use the new algo and
pre-avivo chips use the old algo. Use the "new_pll"
module option to toggle between them.

Subject: drm/nouveau: protect channel create/destroy and irq handler with a
 spinlock

The nv50 pgraph handler (for example) could reenable pgraph fifo access
and that would be bad when pgraph context is being unloaded (we need the
guarantee a ctxprog isn't running).

From 9a391ad8a2cdd7e5be9b6aabb56f4a46683ba377 Mon Sep 17 00:00:00 2001

Subject: drm/nv50: switch to indirect push buffer controls

PFIFO on G80 and up has a new mode where the main ring buffer is simply a
ring of pointers to indirect buffers containing the actual command/data
packets.  In order to be able to implement index buffers in the 3D driver
we need to be able to submit data-only push buffers right after the cmd
packet header, which is only possible using the new command submission
method.

This commit doesn't make it possible to implement index buffers yet, some
userspace interface changes will be required, but it does allow for
testing/debugging of the hardware-side support in the meantime.

Subject: drm/nv50: make pushbuf dma object cover entire vm

This allows us to submit push buffers from any memtype to the hardware.
We'll need this ability for VRAM index buffers at some point.

Subject: drm/nouveau: new gem pushbuf interface, bump to 0.0.16

This commit breaks the userspace interface, and requires a new libdrm for
nouveau to operate again.

The multiple GEM_PUSHBUF ioctls that were present in 0.0.15 for
compatibility purposes are now gone, and replaced with the new ioctl which
allows for multiple push buffers to be submitted (necessary for hw index
buffers in the nv50 3d driver) and relocations to be applied on any buffer.

A number of other ioctls (CARD_INIT, GEM_PIN, GEM_UNPIN) that were needed
for userspace modesetting have also been removed.

Subject: drm/nouveau: fix pramdac_table range checking

get_tmds_index_reg reads some value from stack when mlv happens
to be equal to size of pramdac_table array. Fix it.

i2c_entries seems to be the number of i2c entries,
so with index equal to this number, we could read
invalid data from i2ctable. Fix it.

Subject: drm/nouveau: use dcb connector table for creating drm connectors

This makes this code common to both the nv04 and nv50 paths.

For the moment, we keep the previous behaviour with HDMI/eDP connectors
and report them as DVI-D/DP instead.  This will be fixed once the rest
of the code has been fixed to deal with those types.

+ * This code deals with PGRAPH contexts on NV50 family cards. Like NV40, it's
+ * the GPU itself that does context-switching, but it needs a special
+ * microcode to do it. And it's the driver's task to supply this microcode,
+ * further known as ctxprog, as well as the initial context values, known
+ * as ctxvals.
+ *
+ * Without ctxprog, you cannot switch contexts. Not even in software, since
+ * the majority of context [xfer strands] isn't accessible directly. You're
+ * stuck with a single channel, and you also suffer all the problems resulting
+ * from missing ctxvals, since you cannot load them.
+ *
+ * Without ctxvals, you're stuck with PGRAPH's default context. It's enough to
+ * run 2d operations, but trying to utilise 3d or CUDA will just lock you up,
+ * since you don't have... some sort of needed setup.
+ *
+ * Nouveau will just disable acceleration if not given ctxprog + ctxvals, since
+ * it's too much hassle to handle no-ctxprog as a special case.
+ */
+
+/*
+ * How ctxprogs work.
+ *
+ * The ctxprog is written in its own kind of microcode, with very small and
+ * crappy set of available commands. You upload it to a small [512 insns]
+ * area of memory on PGRAPH, and it'll be run when PFIFO wants PGRAPH to
+ * switch channel. or when the driver explicitely requests it. Stuff visible
+ * to ctxprog consists of: PGRAPH MMIO registers, PGRAPH context strands,
+ * the per-channel context save area in VRAM [known as ctxvals or grctx],
+ * 4 flags registers, a scratch register, two grctx pointers, plus many
+ * random poorly-understood details.
+ *
+ * When ctxprog runs, it's supposed to check what operations are asked of it,
+ * save old context if requested, optionally reset PGRAPH and switch to the
+ * new channel, and load the new context. Context consists of three major
+ * parts: subset of MMIO registers and two "xfer areas".

+ * xfer areas. These are a pain.
+ *
+ * There are 2 xfer areas: the first one is big and contains all sorts of
+ * stuff, the second is small and contains some per-TP context.
+ *
+ * Each area is split into 8 "strands". The areas, when saved to grctx,
+ * are made of 8-word blocks. Each block contains a single word from
+ * each strand. The strands are independent of each other, their
+ * addresses are unrelated to each other, and data in them is closely
+ * packed together. The strand layout varies a bit between cards: here
+ * and there, a single word is thrown out in the middle and the whole
+ * strand is offset by a bit from corresponding one on another chipset.
+ * For this reason, addresses of stuff in strands are almost useless.
+ * Knowing sequence of stuff and size of gaps between them is much more
+ * useful, and that's how we build the strands in our generator.
+ *
+ * NVA0 takes this mess to a whole new level by cutting the old strands
+ * into a few dozen pieces [known as genes], rearranging them randomly,
+ * and putting them back together to make new strands. Hopefully these
+ * genes correspond more or less directly to the same PGRAPH subunits
+ * as in 400040 register.
+ *
+ * The most common value in default context is 0, and when the genes
+ * are separated by 0's, gene bounduaries are quite speculative...
+ * some of them can be clearly deduced, others can be guessed, and yet
+ * others won't be resolved without figuring out the real meaning of
+ * given ctxval. For the same reason, ending point of each strand
+ * is unknown. Except for strand 0, which is the longest strand and
+ * its end corresponds to end of the whole xfer.
+ *
+ * An unsolved mystery is the seek instruction: it takes an argument
+ * in bits 8-18, and that argument is clearly the place in strands to
+ * seek to... but the offsets don't seem to correspond to offsets as
+ * seen in grctx. Perhaps there's another, real, not randomly-changing
+ * addressing in strands, and the xfer insn just happens to skip over
+ * the unused bits? NV10-NV30 PIPE comes to mind...
+ *
+ * As far as I know, there's no way to access the xfer areas directly
+ * without the help of ctxprog.

Subject: drm/nouveau: support version 0x20 displayport tables

Not entirely identical to 0x21, the per-encoder table header lacks the
third init table pointer.  However, our current parsing of the table
should work just fine.

Subject: drm/nouveau: report unknown connector state if lid closed

This is in preference to disconnected.  If there's no other outputs
connected this will cause LVDS to be programmed even with the lid
closed rather than having X fail to start because of no available
outputs.

Subject: RDMA/nes: Add support for KR device id 0x0110

Add support for KR device id 0x0110.  While at it, cleanup
nes_init_phy() by splitting it into nes_init_1g_phy() and
nes_init_2025_phy().

Remove support for NES_PHY_TYPE_IRIS, which was used on an XFP board
that was only manufactured in small quantities and given out for evals
in even smaller quantities.

Subject: thinkpad-acpi: document HKEY event 3006

Event 0x3006 is used to help power management of the ODD in the
UltraBay.  The EC generates this event when the ODD eject button is
pressed (even if the bay is powered down).

Normally, Linux doesn't need this as we keep the SATA link powered
up (which wastes power).  The EC powers up the bay by itself when the
ODD eject button is pressed, and the SATA PHY reports the hotplug.

However, we could also power that SATA link down (and for that matter,
also power down the Ultrabay) if the ODD is left idle for a while with
no disk inside, and use event 0x3006 to know when we need that SATA link
powered back up.

For now, just stop asking for more information when event 0x3006 is
seen, there is no point in pestering users about it anymore.

Subject: thinkpad-acpi: make driver events work in NVRAM poll mode

Thadeu Lima de Souza Cascardo reports this:

Brightness notification does not work until the user writes to
hotkey_mask attribute.  That's because the polling thread will only run
if hotkey_user_mask is set and someone is reading the input device or
if hotkey_driver_mask is set.  In this second case, this condition is
not tested after the mask is changed, because the brightness and
volume drivers are started after the hotkey drivers.

Fix tpacpi_hotkey_driver_mask_set() to call hotkey_poll_setup(), so
that the poller kthread will be started when needed.

argument to SBDC and SWAN is not "set radio to last state on resume".
Rather, it seems to be "if this bit is set, enable radio on resume,
otherwise disable it on resume".

So, the proper way to prepare the radios for S3 suspend is: disable
radio and clear bit 3 on the SBDC/SWAN call to to resume with radio
disabled, and enable radio and set bit 3 on the SBDC/SWAN call to
resume with the radio enabled.

Also, for persistent devices, the rfkill core does not restore state,
so we really need to get the firmware to do the right thing.

We don't sync the radio state on suspend, instead we trust the BIOS to
not do anything weird if we never touched the radio state since boot.
Time will tell if that's a wise way of doing things...

Subject: thinkpad-acpi: lock down video output state access

Given the right combination of ThinkPad and X.org, just reading the
video output control state is enough to hard-crash X.org.

Until the day I somehow find out a model or BIOS cut date to not
provide this feature to ThinkPads that can do video switching through
X RandR, change permissions so that only processes with CAP_SYS_ADMIN
can access any sort of video output control state.

This bug could be considered a local DoS I suppose, as it allows any
non-privledged local user to cause some versions of X.org to
hard-crash some ThinkPads.

Subject: drm/i915: Add dependency on the intel agp module

See http://bugzilla.kernel.org/show_bug.cgi?id=15021

Make sure that the appropriate AGP module is loaded and probed before
trying to set up the DRM.  The DRM already depends on the AGP core,
but in this case we know the specific AGP driver we need too, and can
help users avoid the trap of loading the AGP driver after the DRM
driver.

Subject: drm/i915: reuse i915_gem_object_put_fence_reg for fence stealing code

This has a few functional changes against the old code:

* a few more unnecessary loads and stores to the drm_i915_fence_reg
  objects. Also an unnecessary store to the hw fence register.

* zaps any userspace mappings before doing other flushes. Only changes
  anything when userspace does racy stuff against itself.

* also flush GTT domain. This is a noop, but still try to keep the
  bookkeeping correct.

Subject: drm/i915: extract fence stealing code

The spaghetti logic in there tripped up my brain's code parser for a
few secs. Prevent this from happening again by extracting the fence
stealing code into a seperate functions. IMHO this slightly clears up
the code flow.

v2: Beautified according to ickle's comments.
v3: ickle forgot to flush his comment queue ... Now there's also a
we-are-paranoid BUG_ON in there.
v4: I've forgotten to switch on my brain when doing v3. Now the BUG_ON
actually checks something useful.
v5: Clean up a stale comment as noted by Eric Anholt.

Subject: drm/i915: ensure lru ordering of fence_list

The fence_list should be lru ordered for otherwise we might try
to steal a fence reg from an active object even though there are
fences from inactive objects available. lru ordering was obeyed
for gpu access everywhere save when moving dirty objects from
flushing_list to active_list.

Fixing this cause the code to indent way to much, so I've extracted
the flushing_list processing logic into its on function.

Subject: drm/i915: clean-up i915_gem_flush_gpu_write_domain

Now that we have an exact gpu write domain tracking, we don't need
to move objects to the active list ourself. i915_add_request will
take care of that under all circumstances.

Idea stolen from a patch by Chris Wilson <chris@chris-wilson.co.uk>.

Subject: drm/i915: check for multiple write domains in pin_and_relocate

The assumption that an object has only ever one write domain is deeply
threaded into gem (it's even encoded the the singular of the variable
name). Don't let userspace screw us over.

Subject: drm/i915: enable/disable LVDS port at DPMS time

It would be good to disable the LVDS port when we shut down the panel
to save power.  We haven't done so until now because we had trouble
getting the right LVDS parameters from the BIOS.  I think we're past
that now, so enabling and disabling the port should be safe, though it
would probably be made cleaner with some additional changes to the
display code, where we also bang on the LVDS reg to set the pairing
correctly etc.

Seems to save a bit of power (up to 300mW in my basic wattsup
meter testing).

Subject: drm/i915: Use a dmi quirk to skip a broken SDVO TV output.

This IBM system has a multi-function SDVO card that reports both VGA
and TV, but the system has no TV connector.  The TV connector always
reported as connected, which would lead to poor modesetting choices.

Subject: thinkpad-acpi: fix ALSA callback return status

Clemens Ladisch reports that thinkpad-acpi improperly implements the
ALSA API, and always returns 0 for success for the "put" callbacks
while the API requires it to return "1" when the control value has
been changed in the hardware/firmware.

Rework the volume subdriver to be able to properly implement the ALSA
API.  Based on a patch by Clemens Ladisch <clemens@ladisch.de>.

This fix is also needed on 2.6.33.

Subject: eeepc-laptop: disable wireless hotplug for 1005PE

The wireless hotplug code is not needed on this model, and it disables
the wired ethernet card.  (Like on the 1005HA and 1201N).

Subject: eeepc-laptop: check wireless hotplug events

Before we mark the wireless device as unplugged, check PCI config space
to see whether the wireless device is really disabled (and vice versa).
This works around newer models which don't want the hotplug code, where
we end up disabling the wired network device.

My old 701 still works correctly with this.  I can also simulate an
afflicted model by changing the hardcoded PCI bus/slot number in the
driver, and it seems to work nicely (although it is a bit noisy).

In future this type of hotplug support will be implemented by the PCI
core.  The existing blacklist and the new warning message will be
removed at that point.

Subject: asus-laptop: add wireless and bluetooth status parameter

These to parameter allow to set the status of wlan and bluetooth
device when the module load. On some models, the device will
always be down on boot, so the default behavior is to always
enable these devices.

From 50a90c4d953fe4bb5a87ee5207c4243d25278189 Mon Sep 17 00:00:00 2001
From: Corentin Chary <corentincj@iksaif.net>
Date: Mon, 30 Nov 2009 21:55:12 +0100
Subject: asus-laptop: revise names

asus-laptop now does a lot more than just hotkeys.  Replace the "hotk"
names used throughout the driver with some slightly more appropriate
names.  The actual strings used in kernel messages and sysfs are left
unchanged.

Subject: asus-laptop: callbacks should use "driver data" parameter or field

(Changelog stolen from Alan's patch for eeepc-laptop, but this patch
does the same thing for asus-laptop)

Callback methods should not refer to a variable like "asus" (formally
"hotk").  Instead, they should extract the data they need either from
a "driver data" parameter, or the "driver data" field of the object
which they operate on.  The "asus" variable can then be removed.

In practice, drivers under "drivers/platform" can get away without using
driver data, because it doesn't make sense to have more than one
instance of them.  However this makes it harder to review them for
correctness.  This is especially true for core ACPI developers who have
not previously been exposed to this anti-pattern :-).

This will serve as an example of best practice for new driver writers
(whether they find it themselves, or have it pointed out during review
:-).

From be4ee82d3e44c5940a7f77cae5ed3e942e80a723 Mon Sep 17 00:00:00 2001
From: Corentin Chary <corentincj@iksaif.net>
Date: Sun, 6 Dec 2009 16:27:09 +0100
Subject: asus-laptop: code movement

The asus-laptop driver implements a number of interfaces like the
backlight class driver.  This change makes it easier to examine the
implementation of one interface at at a time, without having to search
through the file to find init() and exit() functions etc.

Subject: asus-laptop: stop using ASUS_HANDLE and use relative methods instead

Stop using ASUS_HANDLE because most of the time it is not needed.
This macro was introduced to display_get and lcd_switch which are not
part of the interface provided by Asus, and are scheduled for removal.

We don't want to send KEY_BRIGHTNESSDOWN or KEY_BRIGHTNESSUP
because it would be a lie to tell userspace that we want
to change the brightness while it's actually done by the
firmware.

There is no way to find the initial lcd state. A quick workaround
is to set it "on" by default. Anyway this feature is scheduled for removal.

Subject: asus-laptop: use device_create_file() instead of platform_group

There is two reason to do that:
- we don't want a "gps" file if the model doesn't have a gps
- we don't want to use global variables anymore

Subject: dmatest: correct raid6 PQ test

The number of PQ sources specified by module parameter "pq_sources"
is always forced odd to fit into dmatest's destination verificaton
scheme. But number of PQ sources and coefficients as passed to the
driver's prep_dma_pq() is not adjusted accordingly.

Fix it now to get correct PQ testing results in the case passed
"pq_sources" parameter is even.

Subject: drm/radeon: r100/r200 ums: block ability for userspace app to trash 0
 page and beyond

radeon's have a special ability to passthrough writes in their internal
memory space directly to PCI, this ability means that if some of the internal
surfaces like the depth buffer point at 0x0, any writes to these will
go directly to RAM at 0x0 via PCI busmastering.

Now mesa used to always emit clears after emitting state, since the
radeon mesa driver was refactored a year or more ago, it was found it
could generate a clear request without ever sending any setup state to the
card. So the clear would attempt to clear the depth buffer at 0x0, which
would overwrite main memory at this point. fs corruption ensues.

Also once one app did this correctly, it would never get set back to 0
making this messy to reproduce.

The kernel should block this from happening as mesa runs without privs,
though it does require the user be connected to the current running X session.

This patch implements a check to make sure the depth offset has been set
before a depth clear occurs and if it finds one it prints a warning and
ignores the depth clear request. There is also a mesa fix to avoid sending
the badness going into mesa.

This only affects r100/r200 GPUs in user modesetting mode.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This commit "disabled" audio on RV710 and RV740 only, leaving RV770 and RV730.
The order is: CHIP_RV770 < CHIP_RV730 < CHIP_RV710 < CHIP_RV740.

It is not needed anway, as we do not even try to enable audio on RV770 and
newer. We call initializing function in r600.c only, not in rv770.c.

If there is something causing green tinges, it's HDMI mode setting for encoder
and I will try to debug that.

Subject: vga_switcheroo: initial implementation (v15)

Many new laptops now come with 2 gpus, one to be used for low power
modes and one for gaming/on-ac applications. These GPUs are typically
wired to the laptop panel and VGA ports via a multiplexer unit which
is controlled via ACPI methods.

4 combinations of systems typically exist - with 2 ACPI methods.
Intel/ATI - Lenovo W500/T500 - use ATPX ACPI method
ATI/ATI - some ASUS - use ATPX ACPI Method
Intel/Nvidia - - use _DSM ACPI method
Nvidia/Nvidia -  - use _DSM ACPI method.

TODO:
This patch adds support for the ATPX method and initial bits
for the _DSM methods that need to written by someone with
access to the hardware.
Add a proper non-debugfs interface - need to get some proper
testing first.

v2: add power up/down support for both devices
on W500 puts i915/radeon into D3 and cuts power to radeon.

v3: redo probing methods, no DMI list, drm devices call to
register with switcheroo, it tries to find an ATPX method on
any device and once there is two devices + ATPX it inits the
switcher.

v4: ATPX msg handling using buffers - should work on more machines

v5: rearchitect after more mjg59 discussion - move ATPX handling to
    radeon driver.

v6: add file headers + initial nouveau bits (to be filled out).

v7: merge delayed switcher code.

v8: avoid suspend/resume of gpu that is off

v9: rearchitect - mjg59 is always right. - move all ATPX code to
radeon, should allow simpler DSM also proper ATRM handling

v10: add ATRM support for radeon BIOS, add mutex to lock vgasr_priv

v11: fix bug in resuming Intel for 2nd time.

v12: start fixing up nvidia code blindly.

v13: blindly guess at finishing nvidia code

v14: remove radeon audio hacks - fix up intel resume more like upstream

v15: clean up printks + remove unnecessary igd/dis pointers

mount debugfs

/sys/kernel/debug/vgaswitcheroo/switch - should exist if ATPX detected
 + 2 cards.

DIS - immediate change to discrete
IGD - immediate change to IGD
DDIS - delayed change to discrete
DIGD - delayed change to IGD
ON - turn on not in use
OFF - turn off not in use

Tested on W500 (Intel/ATI) and T500 (Intel/ATI)

Subject: dell-laptop: Fix build error by making buffer_mutex static

The following build bug (x86, allyesconfig):

  arch/x86/oprofile/built-in.o:(.data+0x250): multiple definition of `buffer_mutex'

Was triggered in -tip testing, caused by this upstream commit:

  116ee77: dell-laptop: Use buffer with 32-bit physical address

There's multiple buffer_mutex's in the kernel. Make this new one
static.

Subject: amd64_edac: Simplify ECC override handling

No need for clearing ecc_enable_override and checking it in two places.
Instead, simply check it during probing and act accordingly. Also,
rename the flag bitfields according to the functionality they actually
represent. What is more, make sure original BIOS ECC settings are
restored when the module is unloaded.

Subject: [ARM] sa1111: avoid using hardcoded IRQ numbers for PCMCIA driver

The IRQs for card detect and status change are currently hardcoded in
SA1111 PCMCIA driver, which can be actually obtained from the .irq[]
from 'struct sa1111_dev' to keep it generic.

Subject: dmaengine: shdma: fix DMA error handling.

Present DMA error ISR in shdma.c is bogus, it locks the system hard in multiple
ways. Fix it to abort all queued transactions on all channels on the affected
controller and giving submitters a chance to get a DMA_ERROR status for aborted
transactions. Afterwards further functionality is again possible without the
need to re-load the driver.

Subject: dmaengine: shdma: convert to platform device resources

The shdma dmaengine driver currently uses numerous macros to support various
platforms, selected by ifdef's. Convert it to use platform device resources and
lists of channel descriptors to specify register locations, interrupt numbers
and other system-specific configuration variants. Unavoidably, we have to
simultaneously convert all shdma users to provide those resources.

Subject: dmaengine: shdma: separate DMA headers.

Separate SH DMA headers into ones, commonly used by both drivers, and ones,
specific to each of them. This will make the future development of the
dmaengine driver easier.

Subject: Debugging options for the DMA engine subsystem

This adds Kconfig options for DEBUG and VERBOSE_DEBUG to the DMA
engine subsystem, I got tired of editing the Makefile manually
each time I want to debug things in here, modelled this on the
debug switches for other subsystems and works like a charm when
working on our DMA engines.

Subject: IB/srp: Split send and recieve CQs to reduce number of interrupts

We can reduce the number of IB interrupts from two interrupts per
srp_queuecommand() call to one by using separate CQs for send and
receive completions and processing send completions by polling every
time a TX IU is allocated.

Receive completion events still trigger an interrupt.

Subject: IB/srp: Clean up error path in srp_create_target_ib()

Instead of repeating the error unwinding steps in each place an error
can be detected, use the common idiom of gotos into an error flow.

The id_table field of the struct pci_driver is constant in <linux/pci.h>
so it is worth to make initialization data also constant.

The semantic match that finds this kind of pattern is as follows:

Subject: i2c-tiny-usb: Fix a comment on bus frequency

The description of the delay parameter is incomplete, it suggests that
there is a direct relation between the delay value and the bus
frequency. In fact, due to additional delays in the i2c bitbanging
code, the i2c clock is always much slower.

Subject: i2c: Add SMBus alert support

SMBus alert support. The SMBus alert protocol allows several SMBus
slave devices to share a single interrupt pin on the SMBus master,
while still allowing the master to know which slave triggered the
interrupt.

This is based on preliminary work by David Brownell. The key
difference between David's implementation and mine is that his was
part of i2c-core, while mine is split into a separate, standalone
module named i2c-smbus. The i2c-smbus module is meant to include
support for all SMBus extensions to the I2C protocol in the future.

The benefit of this approach is a zero cost for I2C bus segments which
do not need SMBus alert support. Where David's implementation
increased the size of struct i2c_adapter by 7% (40 bytes on i386),
mine doesn't touch it. Where David's implementation added over 150
lines of code to i2c-core (+10%), mine doesn't touch it. The only
change that touches all the users of the i2c subsystem is a new
callback in struct i2c_driver (common to both implementations.) I seem
to remember Trent was worried about the footprint of David'd
implementation, hopefully mine addresses the issue.

Subject: i2c: Separate Kconfig option for i2c-smbus

Having a separate Kconfig option for i2c-smbus makes it possible to
build that support as a module even when i2c-core itself is built-in.
Bus drivers which implement SMBus alert should select this option, so
in most cases this option is hidden and the user doesn't have to care
about it.

Subject: i2c: Hook up runtime PM support

Allow I2C drivers to make use of the runtime PM framework by adding
bus implementations of the runtime PM operations. These simply
immediately suspend when the device is idle. The runtime PM framework
provides drivers with off the shelf refcounts for enables and sysfs
control for managing runtime suspend from userspace so is useful even
without meaningful input from the bus.

Subject: DMAENGINE: COH 901 318 configure channel direction

This makes the COH 901 318 configure channel direction (to or from
device) dynamically, instead of being passed in from the platform
data. This was necessary in order to get the MMC/SD-card channel
bidirectional (all other channels on the U300 were either RX or
TX but this one was both). This also sets memcpy() alignent to
even 2^2 (32bit) boundaries, which makes the memcpy() stress tests
start working.

Subject: DMAENGINE: COH 901 318 lli sg offset fix

This makes the COH 901 318 respect the scatter offset field by using
the sg_phys() rather than the sg_dma_address() so we get a pointer
to the actual data we want to send rather than the beginning of the
buffer. Also initialize the lli:s a bit more thoroughly.

Subject: yenta_socket: ENE CB712 CardBus bridge needs special treatment with
 Echo Audio Indigo soundcards

Indigos are well known for distortions when running on some buggy ENE
controllers.  There is a workaround in the yenta driver, but for some
reason it isn't activated on CB712.  However, I own a laptop with such
chip and it seems that it also is affected - I can clearly hear occasional
cracks, especially under heavy network load, and in Windows XP the card is
completely unusable.

This simple change fixed things for me.

Subject: serial: fit blackfin uart over sport driver into common uart
 infrastructure

Fit blackfin uart over sport driver into common uart inftrastructure.  It
is based on the early platform interfaces to get the platform data early
when the console is initilized.

1. Enable sport uart driver to change uart baud, data bit, stop bit at
   runtime.  Bind the index of uart device nodes to physical index of
   sports.

2. Move all platform data into arch specific board files.  Register
   and probe platform device data in both early and normal stages.

3. Console is registered in sport uart driver as well.

4. Remove 500 us block waiting in sport tx stop code by putting a
   dummy data into tx fifo to make sure the sport tx stops when all bytes
   are shifted out except for the dummy data.

5. clean up a bit and fix up coding style.

- * effect accumulates over time until synchronization is lost.
- * If only require 2 samples of the stopbit (by sampling in total 29 samples),
- * then a to short byte as in the case above will be tolerated. Then the 1/3

Subject: serial: copy UART properties of UPF_FIXED_TYPE ports provisioned
 using early_serial_setup

Augment the UPF_FIXED_TYPE logic, which currently applies to UART ports
provisioned using platform_device_register.

The suggested patch applies same logic into 'serial8250_register_ports',
making UART ports provisioned using early_serial_setup inherit their
properties from the uart_config entry.

Subject: serial: synclink_gt: dropped transmit data bugfix

Fix transmit bug that could drop send data if write() called close to
serial transmitter going idle after sending previous data.  Bug is caused
by incorrect use of device information member tx_count.

Driver originally processed one data block (write call) at a time, waiting
for transmit idle before sending more.  tx_count recorded how much data
was loaded in DMA buffers on write(), and was cleared on send completion.
tx_count use was overloaded to record accumulated data from put_char()
callback when transmitter was idle.

A bug was introduced when transmit code was reworked to allow multiple
blocks of data in the tx DMA buffers which keeps transmitter from going
idle between blocks.  tx_count was set to size of last block loaded,
cleared when tx went idle, and monitored to know when to restart
transmitter without proper synchronization.  tx_count could be cleared
when unsent data remained in DMA buffers and transmitter required
restarting, effectively dropping unsent data.

Solution:
1. tx_count now used only to track accumulated data from put_char
2. DMA buffer state tracked by direct inspection of descriptors
   with spinlock synchronization
3. consolidate these tasks in tx_load() :
   a. check for available buffer space
   b. load buffers
   c. restart DMA and or serial transmitter as needed
   These steps were previously duplicated in multiple places,
   sometimes incompletely.
4. fix use of tx_count as active transmit indicator,
   instead using tx_active which is meant for that purpose

Subject: serial: 8250_pci: add support for MCS9865 / SYBA 6x Serial Port Card

This patch is heavily based on an earlier patch found on the linux-serial
mailing list [1], written by Darius Augulis.

The previous incarnation of this patch only supported a 2x serial port
card.  I have added support for my SYBA 6x serial port card, and tested on

Subject: serial: imx: fix NULL dereference Oops when pdata == NULL
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The platform code doesn't have to provide platform data to get sensible
default behaviour from the imx serial driver.

This patch does not handle NULL dereference in the IrDA case, which still
requires a valid platform data pointer (in imx_startup()/imx_shutdown()),
since I don't know whether there is a sensible default behaviour, or
should the operation just fail cleanly.

Subject: serial: Char: cyclades, fix compiler warning

With gcc 4.0.2:
drivers/char/cyclades.c: In function 'cyy_interrupt':
drivers/char/cyclades.c:581: warning: 'info' may be used uninitialized in this function

introduced by

: commit 3aeea5b92210083c7cffd4f08a0bb141d3f2d574
: Author:     Jiri Slaby <jirislaby@gmail.com>

: CommitDate: Sat Sep 19 13:13:16 2009 -0700
:
:    cyclades: introduce cyy_readb/writeb

In fact the true branch which uses uninitialized 'info' can never
happen because chip is always less than ->nchips and channel is
always less than 4 which we alloc.

So behave similar to rx handling and remove the test completely.

I wonder why gcc 4.4.1 doesn't spit a word.

Subject: tty: moxa: remove #ifdef MODULE completely.

We can pass "module parameters" on the kernel command line even when
!MODULE.  So, #ifdef MODULE becomes obsolete.  Also move the declaration
moxa_board_conf at the start of the function, since we were hit by the
following warning.

Subject: ip2: remove #ifdef MODULE from ip2main.c

On the kernel command line we can pass "module parameters".  So #ifdef
MODULE is obsolute now.  Remove it completely.  When CONFIG_PCI=n and
building ip2main.c then we are hit by the following warning.  So move
*pdev into #ifdef CONFIG_PCI.

Subject: Char: synclink, remove unnecessary checks

Stanse found a potential null dereference in mgsl_put_char and
mgsl_write. There is a check for tty being NULL, but it is
dereferenced earlier.

Actually, tty cannot be NULL in .write and .put_char, so remove
the tests.

Subject: serial: bfin_5xx: need to disable DMA TX interrupt too

If we don't disable the DMA TX channel, an inopportune timeout will
trigger the interrupt handler and may cause a dead lock with the spin_lock.

Subject: nozomi: Add tty_port usage

The Nozomi tty handling is very broken on the open/close side (See
http://bugzilla.kernel.org/show_bug.cgi?id=13024 for one example). In
particular it marks the tty as closed on the first close() not on the last.

Most of the logic is pretty solid except for the open/close path so switch
to the tty_port helpers and let them do all the heavy lifting. This is also
fixes all the POSIX behaviour violations in the open/close paths.

Begin by adding the tty port usage

Subject: nozomi: Fix mutex handling

The original author didn't realise the kernel lock was a drop while sleep
lock so did clever (and wrong) things to work around the non need to avoid
deadlocks. Remove the cleverness and the comment (as we don't hold the BKL
now anyway in those paths)

Subject: tty: Fix the ldisc hangup race

This was noticed by Matthias Urlichs and he proposed a fix. This patch
does the fixing a different way to avoid introducing several new race
conditions into the code.

The problem case is TTY_DRIVER_RESET_TERMIOS = 0. In that case while we
abort the ldisc change, the hangup processing has not cleaned up and restarted
the ldisc either.

We can't restart the ldisc stuff in the set_ldisc as we don't know what
the hangup did and may touch stuff we shouldn't as we are no longer
supposed to influence the tty at that point in case it has been re-opened
before we get rescheduled.

Instead do it the simple way. Always re-init the ldisc on the hangup, but
use TTY_DRIVER_RESET_TERMIOS to indicate that we should force N_TTY.

Subject: tty: Keep the default buffering to sub-page units

We allocate during interrupts so while our buffering is normally diced up
small anyway on some hardware at speed we can pressure the VM excessively
for page pairs. We don't really need big buffers to be linear so don't try
so hard.

In order to make this work well we will tidy up excess callers to request_room,
which cannot itself enforce this break up.

Subject: tty: Add a new VT mode which is like VT_PROCESS but doesn't require a
 VT_RELDISP ioctl call

This new VT mode (VT_PROCESS_AUTO) does everything that VT_PROCESS does
except that it doesn't wait for a VT_RELDISP ioctl before switching
away from a VT with that mode.

If the X server eventually uses this new mode, debugging and crash
recovery should become easier. This is because even when currently in
the VT of a frozen X server it would still be possible to switch out
by doing SysRq-r and then CTRL-<number of a text vt>, sshing in and
doing chvt <number of a text vt>, or any other method of VT switching.
The general concensus on #xorg-devel seems to be that it should be
safe to use this with X now that we have KMS.

This also moves the VT_ACKACQ define to a more appropriate place,
for clarity's sake.

is unloaded). If you try to reload the module, the following message
appears:

register things with the same name in the same directory.

This patch remove the uart things when the driver fails.

Subject: jsm: fixing error if the driver fails to load

Currently if the driver fails to register on port, the kernel
crashes with the following stack:

cpu 0x1: Vector: 300 (Data Access) at [c0000000e0303090]
    pc: c00000000039aa74: .__mutex_lock_slowpath+0x44/0x10c
    lr: c00000000039aa58: .__mutex_lock_slowpath+0x28/0x10c
[c0000000e03033c0] c00000000026b074 .uart_remove_one_port+0xbc/0x16c
[c0000000e0303460] d0000000000e0554 .jsm_remove_uart_port+0x8c/0x10c [jsm]
[c0000000e03034f0] d0000000000dc034 .jsm_remove_one+0x34/0x108 [jsm]
[c0000000e0303590] c0000000001f4aa0 .pci_device_remove+0x48/0x74
...

This patch just fixes the code flow to abort the load when an
error is detected.

+  * The i.MX21 USB hardware contains
+  *    * 32 transfer descriptors (called ETDs)
+  *    * 4Kb of Data memory
+  *
+  * The data memory is shared between the host and fuction controlers
+  * (but this driver only supports the host controler)
+  *
+  * So setting up a transfer involves:
+  *    * Allocating a ETD
+  *    * Fill in ETD with appropriate information
+  *    * Allocating data memory (and putting the offset in the ETD)
+  *    * Activate the ETD
+  *    * Get interrupt when done.
+  *
+  * An ETD is assigned to each active endpoint.
+  *
+  * Low resource (ETD and Data memory) situations are handled differently for
+  * isochronous and non insosynchronous transactions :
+  *
+  * Non ISOC transfers are queued if either ETDs or Data memory are unavailable
+  *
+  * ISOC transfers use 2 ETDs per endpoint to achieve double buffering.
+  * They allocate both ETDs and Data memory during URB submission
+  * (and fail if unavailable).

Subject: USB: cxacru: check data length is not negative

When attempting to read data that is not actually
an array of values, the length may be negative
which causes an Oops due to a likely access off
the end of the data array.

This bug should not occur under normal use unless
the device returns an invalid response.

Subject: USB: cxacru: check device isn't being removed during sysfs calls

It is possible for usb_get_intfdata() to return NULL if
sysfs is accessed while the module is being unloaded or
the device is being removed.

Move the access code to an inline function in usbatm.h,
and return -ENODEV if any of the pointers are NULL.

It should not be possible for the instance data or atm
device to be invalid until after unbind() completes and
the sysfs attributes have been removed.

Subject: USB: cxacru: firmware writes on OHCI are slow, log progress

Firmware writing takes 256ms per 4KB with OHCI, which
is very slow compared to 7ms per 4KB with UHCI.

Until I have access to a hardware USB analyser it may
not be possible to determine why this happens.

Instead of appearing to do nothing, log progress when
writing firmware and then log the ATM device information
when finished. Remove an unnecessary 4 second delay.

Subject: USB: cxacru: add write-only sysfs attribute for modem configuration

The modem can be configured using CM_REQUEST_CARD_DATA_SET,
although CM_REQUEST_CARD_DATA_GET does not return any data.

Tested by setting the modulation (0x0a) option.

There is a list of parameters in the following archive,
but the meaning of many of them is not well documented:
  http://sourceforge.net/project/shownotes.php?release_id=301825

This source also indicates that the highest parameter set
is 0x4a but this varies by model so an arbitrary limit of
0x7f has been used (the index is a 32-bit integer).

Subject: USB: cxacru: remove cxacru-cf.bin loader

This has never worked properly because wsize passed to
cxacru_cm() is incorrectly set to the number of values
instead of the data bytes. The maximum number of values
that can be set at once is 7 which means the device will
not get enough data to work with and none of the
configuration values will be used.

At least one existing cxacru-cf.bin file contains invalid
data which will prevent the modem from syncing properly.

Fixing it is likely to break existing systems, and the
new sysfs interface for setting configuration parameters
can provide the same functionality. A script is provided
to convert from the original format.

Subject: USB: fix occasional ULPI timeouts with ehci-mxc

On various mxc boards, the intial ULPI reads resulted in a timeout
which prevented the transceiver to be identified and thus the ehci
device to be probed.

Initializing the hardware lines connected to the transceiver (through
pdata->init call) before actually enabling clocks and configuring
registers in the devices fixes this problem.

Subject: USB: check the endpoint type against the pipe type

This patch (as1316) adds some error checking to usb_submit_urb().
It's conditional on CONFIG_USB_DEBUG, so it won't affect normal users.
The new check makes sure that the actual type of the endpoint
described by urb->pipe agrees with the type encoded in the pipe value.

The USB error code documentation is updated to include the code
returned by the new check, and the usbfs SUBMITURB handler is updated
to use the correct pipe type when legacy user code tries to submit a
bulk transfer to an interrupt endpoint.

Subject: USB: xhci: Fix error path when configuring endpoints.

If we fail to queue an evaluate context command or a configure endpoint
command to the command ring in xhci_configure_endpoint(), we need to
remove the xhci_command structure from the device's command list before
returning.  If the command is left on the command list, it will sit there
indefinitely, blocking commands submitted after this fails.

Subject: USB: xhci: Allow allocation of commands without input contexts.

The xhci_command structure is the basic structure for issuing commands to
the xHCI hardware.  It contains a struct completion (so that the issuing
function can wait on the command), command status, and a input context
that is used to pass information to the hardware.  Not all commands need
the input context, so make it optional to allocate.  Allow
xhci_free_container_ctx() to be passed a NULL input context, to make
freeing the xhci_command structure simple.

Refactor the code to clear the port change bits in the port status

Remove a redundant port status read that was supposed to unblock any
posted writes.  We read the port after the write to get the updated status
for debugging, so the port read after that is unnecessary.

Subject: USB: xhci: Allow roothub ports to be disabled.

Add the hub emulation code to allow ports on an xHCI root hub to be
disabled.  Add the code to clear the port enabled/disabled bit, and clear
the port enabled/disabled change bit.  Like EHCI, the port cannot be
enabled by setting the port enabled/disabled bit.  Instead, a port is
enabled by the host controller after a reset.

Subject: USB: xhci: Notify the xHC when a device is reset.

When a USB device is reset, the xHCI hardware must know, in order to match
the device state and disable all endpoints except control endpoint 0.
Issue a Reset Device command after a USB device is successfully reset.
Wait on the command to finish, and then cache or free the disabled
endpoint rings.

There are four different USB device states that the xHCI hardware tracks:
 - disabled/enabled - device connection has just been detected,
 - default - the device has been reset and has an address of 0,
 - addressed - the device has a non-zero address but no configuration has
   been set,
 - configured - a set configuration succeeded.

The USB core may issue a port reset when a device is in any state, but the
Reset Device command will fail for a 0.96 xHC if the device is not in the
addressed or configured state.  Don't consider this failure as an error,
but don't free any endpoint rings if this command fails.

A storage driver may request that the USB device be reset during error
handling, so use GPF_NOIO instead of GPF_KERNEL while allocating memory
for the Reset Device command.

Subject: USB: Add call to notify xHC of a device reset.

Add a new host controller driver method, reset_device(), that the USB core
will use to notify the host of a successful device reset.  The call may
fail due to out-of-memory errors; attempt the port reset sequence again if
that happens.  Update hub_port_init() to allow resetting a configured
device.

Subject: USB: ehci-fsl: Fix sparse warnings

This patch fixes following warnings:

ehci-fsl.c:43:5: warning: symbol 'usb_hcd_fsl_probe' was not declared. Should it be static?

Subject: USB: ehci-fsl: Add power management support

EHCI FSL controller preserve its state during sleep mode, so nothing
fancy needs to be done.

Though, during 'deep sleep' mode (as found in MPC831x CPUs) the
controller turns off and needs to be reinitialized upon resume.

This patch adds support for hibernation and resuming after deep sleep.
Based on Dave Liu and Jerry Huang's work[1].

Subject: USB: cypress_m8: allow unstable baud rates

I've got a crappy cypress converter here, and while running at higher
baud rates craps out on throughput, it works fine with lower ones.
While it'd be nice to simply use a lower baud rate, not all devices
can be configured this way, and it is possible to (slowly) interact
at higher rates by sending a byte at a time.  So let people force
higher rates when they need it via a module parameter.

Subject: USB: gadget: use ep5 for bulk-in and ep6 for bulk-out for Blackfin
 MUSB

Normally, the musb uses ep1 as the bidirectional bulk endpoint.  This won't
work on the Blackfin musb as all endpoints (except ep0) are unidirectional.
Further, ep1-ep4 have a small 128 byte FIFO which makes them undesirable
for bulk endpoints (which need more like a 512 byte FIFO).  This leaves us
with ep5-ep7 which have 1024 byte FIFOs and can be configured as either
in/out and bulk/interrupt/iso on the fly.

Subject: usbmon: add bus number to text API

Due to a simple oversight when bus zero was added, the text API fails to
deliver the bus number in 'E' messages (which are equivalent of 'C'
messages, only for error case). This makes it harder, for instance,
use a search-and-highlight in a text editor. So fix it.

Also, Alan Stern requested adding timestamps to 'E' messages. This is
purely cosmetic, but makes it easier to read the trace. This is done
for both text and binary APIs.

Subject: USB: cdc_acm: Add support for pbLua console port

The pbLua firmware (http://pblua.com/) for the Lego Mindstorms NXT
provides a CDC ACM port for it's serial console.

This used to be detected automatically, but this support has been
dropped, probably for sensible reasons.

Explicitly add support for this device by adding an item to the
device ID table.

Subject: USB: cdc_acm: Silence "It is not a modem." error for pbLua devices

The pbLua console port is known to not be a modem, so it is
unnecessary to be told this when it is plugged in.

Add NOT_A_MODEM quirk to tell the driver that we know this already
and hence not to warn us, and mark the pbLua console port.

From 16985408b5c48585762ec3b9b7bae1dec4ad7437 Mon Sep 17 00:00:00 2001

Subject: USB: retain USB device power/wakeup setting across reconfiguration

Currently a non-root-hub USB device's wakeup settings are initialized when the
device is set to a configured state using device_init_wakeup(), but this is not
correct as wakeup is split into "capable" (can_wakeup) and "enabled"
(should_wakeup).  The settings should be initialized instead in the device
initialization (usb_new_device) with the "capable" setting disabled and the
"enabled" setting enabled.  The "capable" setting should be set based on the
device being configured or unconfigured, and "enabled" setting set based on
the sysfs power/wakeup control.

This patch retains the sysfs power/wakeup setting of a non-root-hub USB device
over a USB device re-configuration, which can happen (for example) after a
suspend/resume cycle.

more sense.  Based on a recommendation from David Vrabel

Subject: USB: ftdi_sio: remove unnecessary initialisations

Return values are being initialised to zero only to be unconditionally
assigned to a few instructions later. This may give the impression that
zero is returned on success, which is not the case.

Note also that ftdi_NDI_device_setup never reports errors.

Subject: USB: musb: Add new fifo table for a OMAP3 errata

We have observed MSC data read corruption when USB LAN device is
also connected and it's interface is up.

Silicon team has confirmed an errata where in all the active
transfers should use FIFO space either in first 8K or next 8K.
So far we have observed the issue in above use case scenario.

As a workaround to it, adding a new FIFO config (5) fitting well
within first 8K which can be used for such use cases.

Subject: usb: musb: workaround MUSB DMA_INTR sometimes reads zero

MUSB DMA_INTR register may sometimes read zero when infact there
was a pending interrupt. Workaround this by reading the DMA_COUNT
values for all enabled channels when this condition occurs.
Flag these channels as the ones needing to be serviced.

Additionally, the absence of a debug print meant we would never
catch a spurious DMA interrupt in MUSB. So this patch adds a
debug print in the IRQ handler.

Subject: usb: musb: workaround toggle bug when doing bulk transfer after isoc

This patch implements the work around for a Mentor controller related
bug where it's observed a BULK Tx toggle error on the bus when a
BULK IO gets scheduled on an endpoint that was earlier used for
handling ISOC transaction and needed to start on 1 toggle.  When such
a situation arises even if the TXCSR toggle bits are programmed
correctly by the musb driver the data gets transmitted with 0 toggle
which leads to toggle error on the bus and the BULK transaction fails.
In case of MSC write, the device gets reset by the Host.

This Mentor bug is observed on almost all Mentor versions (1.3, 1.5,
1.8).  Confirmed on DM644x, DM355, DM365, OMAPL13x platforms.

Subject: usb: musb: Fix cppi_channel_abort() function to handle Tx abort
 correctly

This patch fixes the Tx abort/teardown logic. We now wait for the teardown
completion interrupt and acknowledge the same by setting the tx_complete
register to 0.

This change is needed to ensure that abort processing works on DM365 platform.
Without this change after completion of abort processing the system is
overwhelmed with continuous stream of abort interrupts.

This change has been tested on all CPPI3.x platforms (DM644x, DM646x, DM35x,
DM36x).

Some of the board might use external Vbus power supply on musb
interface which would require to program ULPI_BUSCONTROL register.

Adding 'extvbus' flag which can be set from such boards which will
be checked at musb driver files before programming ULPI_BUSCONTROL.

Subject: usb: host: ehci: adding regulator framework in ehci-omap.c driver.

OMAP3 has three HS USB ports so it can have three different regulator
for each PHY connected to each port.

Currently these regulators are assumed to be optional and driver doesn't
fail but continue with the initialization if it doesn't get any regulators.

Regulator supply names has to be mapped in board files as 'hsusbN' where
'N' is port number and can be {0, 1 ,2}.

Subject: USB: serial: fix DMA buffers on stack for io_edgeport.c

The original code was passing a stack variable as a dma buffer, so I
made it an allocated variable.  Instead of adding a bunch of kfree()
calls, I changed all the error return paths to gotos.

Also I noticed that the error checking wasn't correct because
usb_get_descriptor() can return negative values.

While I was at it, I made an unrelated white space change by moving
the unicode_to_ascii() on to one line.

Subject: USB: FHCI: Correct the size argument to kzalloc

urb_priv->tds has type struct td **, not struct td *, so the
elements of the array should have pointer type, not structure type.

Convert kzalloc to kcalloc as well.

The semantic patch that makes this change is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@disable sizeof_type_expr@
type T;
T **x;

  x =

Subject: USB: xhci: Fix compile issues with xhci_get_slot_state()

Randy Dunlap reported this error when compiling the xHCI driver:

linux-next-20100104/drivers/usb/host/xhci.h:1214:
sorry, unimplemented: inlining failed in call to 'xhci_get_slot_state': function body not available

The xhci_get_slot_state() function belongs in xhci-dbg.c, since it
involves debugging internal xHCI structures.  However, it is only used in
xhci-hcd.c.  Some toolchains may have issues since the inlined function
body is not in the xhci.h header file.  Remove the inline keyword to avoid
this.

Subject: USB: unusual_devs: Add support for multiple Option 3G sticks

Enable the SD-Card interface on multiple Option 3G sticks.
The unusual_devs.h entry is necessary because the device descriptor is
vendor-specific. That prevents usb-storage from binding to it as an interface
driver.

Subject: USB: Use bInterfaceNumber in bandwidth allocations.

USB devices do not have to sort interfaces in their descriptors based on
the interface number, and they may choose to skip interface numbers.  The
USB bandwidth allocation code for installing a new configuration assumes
the for loop variable will match the interface number.  Make it use the
interface number (bInterfaceNumber) in the descriptor instead.

Subject: USB: change locking for device-level autosuspend

This patch (as1323) changes the locking requirements for
usb_autosuspend_device(), usb_autoresume_device(), and
usb_try_autosuspend_device().  This isn't a very important change;
mainly it's meant to make the locking more uniform.

The most tricky part of the patch involves changes to usbdev_open().
To avoid an ABBA locking problem, it was necessary to reduce the
region protected by usbfs_mutex.  Since that mutex now protects only
against simultaneous open and remove, this posed no difficulty -- its
scope was larger than necessary.

And it turns out that usbfs_mutex is no longer needed in
usbdev_release() at all.  The list of usbfs "ps" structures is now
protected by the device lock instead of by usbfs_mutex.

Subject: USB: consolidate remote wakeup routines

This patch (as1324) makes a small change to the code used for remote
wakeup of root hubs.  hcd_resume_work() now calls the hub driver's
remote-wakeup routine instead of implementing its own version.

The patch is complicated by the need to rename remote_wakeup() to
usb_remote_wakeup(), make it non-static, and declare it in a header
file.  There's also the additional complication required to make
everything work when CONFIG_PM isn't set; the do-nothing inline
routine had to be moved into the header file.

Subject: USB: implement usb_enable_autosuspend

This patch (as1326) adds usb_enable_autosuspend() and
usb_disable_autosuspend() routines for use by drivers.  If a driver
knows that its device can handle suspends and resumes correctly, it
can enable autosuspend all by itself.  This is equivalent to the user
writing "auto" to the device's power/level attribute.

The implementation differs slightly from what it used to be.  Now
autosuspend is disabled simply by doing usb_autoresume_device() (to
increment the usage counter) and enabled by doing
usb_autosuspend_device() (to decrement the usage counter).

The set_level() attribute method is updated to use the new routines,
and the USB Power-Management documentation is updated.

The patch adds a usb_enable_autosuspend() call to the hub driver's
probe routine, allowing the special-case code for hubs in quirks.c to
be removed.

Subject: USB: change handling of negative autosuspend delays

This patch (as1327) changes the way negative autosuspend delays
prevent device from autosuspending.  The current code checks for
negative values explicitly in the autosuspend_check() routine.  The
updated code keeps things from getting that far by using
usb_autoresume_device() to increment the usage counter when a negative
delay is set, and by using usb_autosuspend_device() to decrement the
usage counter when a non-negative delay is set.

This complicates the set_autosuspend() attribute method code slightly,
but it will reduce the overall power management overhead.

Subject: USB: convert to the runtime PM framework

This patch (as1329) converts the USB stack over to the PM core's
runtime PM framework.  This involves numerous changes throughout
usbcore, especially to hub.c and driver.c.  Perhaps the most notable
change is that CONFIG_USB_SUSPEND now depends on CONFIG_PM_RUNTIME
instead of CONFIG_PM.

Several fields in the usb_device and usb_interface structures are no
longer needed.  Some code which used to depend on CONFIG_USB_PM now
depends on CONFIG_USB_SUSPEND (requiring some rearrangement of header
files).

The only visible change in behavior should be that following a system
sleep (resume from RAM or resume from hibernation), autosuspended USB
devices will be resumed just like everything else.  They won't remain
suspended.  But if they aren't in use then they will naturally
autosuspend again in a few seconds.

Subject: USB: fix crash in uhci_scan_schedule

When hardware is removed on a Stratus, the system may crash like this:

ACPI: PCI interrupt for device 0000:7c:00.1 disabled
Trying to free nonexistent resource <00000000a8000000-00000000afffffff>

usb usb2: USB disconnect, address 1
usb 2-1: USB disconnect, address 2
Unable to handle kernel paging request at 0000000000100100 RIP:
 [<ffffffff88021950>] :uhci_hcd:uhci_scan_schedule+0xa2/0x89c

 #4 [ffff81011de17e50] uhci_scan_schedule at ffffffff88021918
 #5 [ffff81011de17ed0] uhci_irq at ffffffff88023cb8
 #6 [ffff81011de17f10] usb_hcd_irq at ffffffff801f1c1f

 #8 [ffff81011de17f50] __do_IRQ at ffffffff800ba749

This occurs because an interrupt scans uhci->skelqh, which is
being freed. We do the right thing: disable the interrupts in the
device, and do not do any processing if the interrupt is shared
with other source, but it's possible that another CPU gets
delayed somewhere (e.g. loops) until we started freeing.

The agreed-upon solution is to wait for interrupts to play out
before proceeding. No other bareers are neceesary.

A backport of this patch was tested on a 2.6.18 based kernel.
Testing of 2.6.32-based kernels is under way, but it takes us
forever (months) to turn this around. So I think it's a good
patch and we should keep it.

Tracked in RH bz#516851

Subject: USB: Move hcd free_dev call into usb_disconnect to fix oops

USB: Move hcd free_dev call into usb_disconnect

I found a way to oops the kernel:

1. Open a USB device through devio.
2. Remove the hcd module in the host kernel.
3. Close the devio file descriptor.

The problem is that closing the file descriptor does usb_release_dev
as it is the last reference.  usb_release_dev then tries to invoke
the hcd free_dev function (or rather dereferencing the hcd driver
struct).  This causes an oops as the hcd driver has already been
unloaded so the struct is gone.

This patch tries to fix this by bringing the free_dev call earlier
and into usb_disconnect.  I have verified that repeating the
above steps no longer crashes with this patch applied.

Subject: USB serial: make USB device id constant
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The id_table field of the struct usb_device_id is constant in <linux/usb.h>
so it is worth to make the initialization data also constant.

The semantic match that finds this kind of pattern is as follows:

Subject: USB image: make USB device id constant
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The id_table field of the struct usb_device_id is constant in <linux/usb.h>
so it is worth to make the initialization data also constant.

The semantic match that finds this kind of pattern is as follows:

Subject: USB misc: make USB device id constant
MIME-Version: 1.0

The id_table field of the struct usb_device_id is constant in <linux/usb.h>
so it is worth to make the initialization data also constant.

The semantic match that finds this kind of pattern is as follows:

Carsten Juttner thankfully investigated a bit and found out some details
about the chipset used in the 4G W14 device I recently added to
option.c.

I think this information is useful for reference, so I'd be happy if you
could include those bits.

Subject: USB: serial: option.c: Add blacklisting infrastructure for special
 device handling

As suggested by Matthias Urlichs, this patch adds a somehow generic
mechanism for special handling of devices which don't support all bits
expected by this driver.

The blacklisting code is heavily stolen from sierra.c, but extended to
support different special cases.

For now, one case is implemented (OPTION_BLACKLIST_SENDSETUP), targeted
at the 4G W14 device: devices which don't understand the setting of
RTS/DTR in option_send_setup() causing a USB timeout of 5 s in any
userspace open() which leads to errors in most userspace applications.

In addition, I prepared another case for devices with interfaces which
shall not be accessed by this driver (targeted at the D-Link DWM 652).

However, OPTION_BLACKLIST_RESERVED_IF is not fully implemented yet as I
have no device to test this. Anyone volunteering to help here?  If not,
I'll contact the guys who added D-Link DWM 652 support soon.

The 4G XS Stick W14 seems to not understand RTS/DTR setting in
option_send_setup causing long timeouts on any open() which disturbs a
lot of well-known userspace applications like minicom or ModemManager.

Therefore, we enable OPTION_BLACKLIST_SENDSETUP blacklisting for it.

Subject: USB: BKL removal: rio500

This driver had used BKL to guard against disconnect but
was incorrectly converted leaving an SMP race.
BKL was added to disconnect() to fix this race
BKL was removed from ioctl() as the mutex is sufficient
on its own.

Subject: USB: remove the berry_charge driver

The Barry project's userspace program, bcharge, can better handle this
device and functionality, and it also works with the latest phones,
which this driver does not support.  So remove it, as the userspace code
should be used instead.

Subject: USB: gadget: Add DEVTYPE support for Ethernet functions

The problem with Ethernet based networking devices is to clearly
identify what's their usage. Special interfaces like bridges, WiFi,
Bluetooth, WiMAX or WWAN are already using DEVTYPE identification.

This patch marks the Ethernet functions of gadgets from the device
type "gadget". Automatic setup of these interfaces can now happen
from userspace without the need of hardcoding the network interface
name.

The variables priv and portdata are initialized twice to the same (side
effect-free) expressions.  Drop one initialization in each case.

Subject: USB: remove obsolete config in kernel source (USB_HCD_DMA)

The configuration Option USB_HCD_DMA is not reachable in KConfig so
this piece of Code is effectively dead and useless. Remove it to avoid
confusion.

Subject: usb: musb: Add context save and restore support

Adding support for MUSB register save and restore during system
suspend and resume.

Changes:
        - Added musb_save/restore_context() functions
        - Added platform specific musb_platform_save/restore_context()
          to handle platform specific jobs.
        - Maintaining BlackFin compatibility by adding read/write
          functions for registers which are not available in BlackFin

Tested system suspend and resume on OMAP3EVM board.

we have those addresses already ioremaped, so let's
use our __raw_readl/writel wrappers.

Subject: USB: s3c-hsotg: replace deprecated dma_sync_single()

This replaces deprecated dma_sync_single() with dma_sync_single_for_cpu().

There is no functional change because dma_sync_single() simply calls
dma_sync_single_for_cpu():

static inline void __deprecated dma_sync_single(struct device *dev,
       	      	   				dma_addr_t addr, size_t size,
						enum dma_data_direction dir)
{
	dma_sync_single_for_cpu(dev, addr, size, dir);
}

This fixes the following compile warnings:

drivers/usb/gadget/s3c-hsotg.c: In function 's3c_hsotg_unmap_dma':
drivers/usb/gadget/s3c-hsotg.c:376: warning: 'dma_sync_single' is deprecated (declared at /home/fujita/git/linux-2.6/include/linux/dma-mapping.h:109)

Subject: USB: io_edgeport: eliminate get_string()

Johan Hovold points out that get_string() is basically just a
re-implimentation of usb_string().  It is also buggy.  It does DMA on
the stack and it doesn't handle negative returns from
usb_get_descriptor().  Plus unicode_to_ascii() is a rubbish function and
moving to usb_string() avoids using it.

Let's eliminate get_string() entirely.

Subject: USB: serial: add support for serial port on the moschip 7715

Add support for the serial port on devices based on the MosChip 7715,
which provides a serial and parallel port on a single usb interface.
This is added to the existing driver for the Moschip 7720 dual serial
port device.  The 7715 is very similiar to the 7720, requiring only the
addition of a calc_num_ports() function, a separate interrupt-in
endpoint callback, and some manipulation of the port pointers added to
the attach() function to correct the fact that the usbserial core
erroneously assigns the first bulk in/out endpoint pair to the serial
port (the 7715 uses these for its parallel port).  There is no support
for the 7715's parallel port yet.

Subject: USB: pxa27x_udc: Fix deadlocks on request queueing

As reported by Antonio, there are cases where the ep->lock
can be taken twice, triggering a deadlock.
The typical sequence is :
 irq_handler
   \
    -> gadget.complete()
       \
        -> pxa27x_udc.pxa_ep_queue() : ep->lock is taken
           \
            -> gadget.complete()
               \
                -> pxa27x_udc.pxa_ep_queue() : ep->lock is taken
                                               ==> *deadlock*
The patch fixes this by :
 - releasing the lock each time gadget.complete() is called
 - adding a check in handle_ep() to detect a recursive call,
   in which case the function becomes on no-op.

The patch is still not good enough for ep0. For this unique
endpoint, another well thought over patch will be needed.

Subject: USB: musb: set version of Blackfin version

All current Blackfin parts are using RTL v1.9, but they don't expose the
hardware registers to probe this dynamically.  So hardcode the version to
v1.9 for now.

Need to move the local hwvers related defines higher up in the header so
that sub-musb headers may utilize them.

Subject: USB: mass_storage: eject LUNs on thread exit

Adds a fallback which forces all LUNs ejection (including
non-removable and with prevent_medium_removal flag) when mass storage
function (MSF) worker thread exits and gadget fails to handle the
situation.

Previously, if thread_exits was not specified mass storage function
(MSF) did nothing when exiting thread as it's unclear for *function*
what to do when it's thread terminates so responsibility of handling
this situation was left to the *gadget* using the function.

The g_mass_storage handled the situation by unregistering itself (the
same thing that file storage gadget does).  However, g_multi did
nothing and so MSF did not eject LUNs which prevented file system
unmounting.

Subject: USB: g_mass_storage: superfluous and missing packets fixed

The mass storage function responded needlessly to a set
configuration packet.  This was a leftover from converting
gadget (file storage gadget) into a composite function.

Moreover, it has failed to respond to get max LUN request.
Adding request queueing made the function work better.

Subject: USB: ftdi_sio: Replace BKL with a mutex

As Alan Cox have pinpointed the driver still required protection against
parallels calls to the config ioctl(). If lock is still necessary the use of
BKL is abused here. So replace BKL with a more convenient mutex.

Subject: USB: isp1760: Flush the D-cache for the pipe-in transfer buffers

When the HDC driver writes the data to the transfer buffers it pollutes
the D-cache (unlike DMA drivers where the device writes the data). If
the corresponding pages get mapped into user space, there are no
additional cache flushing operations performed and this causes random
user space faults on architectures with separate I and D caches
(Harvard) or those with aliasing D-cache.

Subject: USB: Remove unsupported usb gadget drivers

A bunch of USB gadget drivers where never ported from the linux 2.4
series to 2.6 kernels. However there's some code still in the tree for
them which isn't used and is probably untested for ages.

As the chance of these drivers being forward ported is probably quite
small now it might be time to get rid of them.

Subject: USB: atmel uaba: Adding invert vbus_pin

Adding vbus_pin_inverted so that the usb detect pin can be active high
or low depending on HW implementation also replaced the
gpio_get_value(udc->vbus_pin); with a call to vbus_is_present(udc); This
allows the driver to be loaded and save about 0,15W on the consumption.

Add support for USB serial interface provided by ViVOtech ViVOpay devices via
new driver vivopay-serial.  Currently only the ViVOpay 8800 device is supported,
but support for similar devices can be added by adding the appropriate device
IDs to the driver.

Subject: USB: ehci-dbgp: split PID register updates for IN and OUT pipes

This patch addresses two problems:

1) Bulk reads should always use the DATA0 for the pid, and the write
   PID should toggle between DATA0 and DATA1.  The fix is using
   dbgp_pid_write_update() and dbgp_pid_read_update().

2) The delay loop for waiting for a transaction was not long enough to
   always complete the initial handshake inside dbgp_wait_until_done().
   After the initial handshake the maximum delay length is never reached.

The combined result of these two changes allows for the removal of the
forced resynchronization where a bulk write was issued with a dummy
data payload only to get the device to start accepting data writes
again.

Subject: USB: xhci: Fix finding extended capabilities registers

According "5.3.6 Capability Parameters (HCCPARAMS)" of xHCI rev0.96 spec,
value of xECP register indicates a relative offset, in 32-bit words,
from Base to the beginning of the first extended capability.
The wrong calculation will cause BIOS handoff fail (not handoff from BIOS)
in some platform with BIOS USB legacy sup support.

Subject: USB: serial: sierra driver indat_callback fix

A crash has been reported with sierra driver on disconnect with
Ubuntu/Lucid distribution based on kernel-2.6.32.
The cause of the crash was determined as "NULL tty pointer was being
referenced" and the NULL pointer was passed by sierra_indat_callback().

This patch modifies sierra_indat_callback() function to check for NULL
tty structure pointer. This modification prevents a crash from happening
when the device is disconnected.

This patch fixes the bug reported in Launchpad:
  https://bugs.launchpad.net/ubuntu/+source/linux/+bug/511157

Subject: USB: ehci: omap: use default interrupt threshold

The current driver reduces the interrupt threshold to 1 microframe.
This was an accidental change and is not really required.
The default of 8 microframes will do just fine. So change it back.

Subject: USB: OHCI: DA8xx/OMAP-L1x glue layer

Texas Instruments DA8xx/OMAP-L1x OHCI glue layer.

This OHCI implementation is not without quirks: there's only one physical port
despite the root hub reporting two; the port's power control and over-current
status bits are not connected to any pins, however, at least on the DA830 EVM
board, those signals are connected via GPIO, thus the provision was made for
overriding the OHCI port power and over-current bits at the board level...

Subject: usb-storage: use max_hw_sectors instead of max_sectors

This patch (as1347) makes some adjustments to the way usb-storage
handles the request-queue parameters.

USB host controllers are able to handle arbitrarily long
scatter-gather lists, since they are limited only by main memory and
not by the controller hardware.  Hence the sg_tablesize field in the
host template can be increased to the maximum value.

Drivers like usb-storage aren't supposed to touch the queue's
max_sectors parameter; instead they are supposed to use the
max_hw_sectors value.  Accordingly, the patch replaces calls of
queue_max_sectors() with calls of queue_max_hw_sectors().  Oddly
enough, the blk_queue_max_sectors() routine is nevertheless still
appropriate.

The existing code imposes a limit of SCSI_DEFAULT_MAX_SECTORS (1024)
on the values accepted by the max_sectors attribute file.  There's no
reason not to accept larger values, so the limit is removed.  (It
would be nice to change the file's name to max_hw_sectors, but the old
name is already a well-established API.)

Due to a misplaced parenthesis the usbat_write_block() return value was not
stored, but a boolean. USB_STOR_TRANSPORT_NO_SENSE and USB_STOR_TRANSPORT_ERROR
were returned as USB_STOR_TRANSPORT_FAILED.

Subject: USB: don't read past config->interface[] if usb_control_msg() fails
 in usb_reset_configuration()

While looping over the interfaces, if usb_hcd_alloc_bandwidth() fails it calls
hcd->driver->reset_bandwidth(), so there was no need to reinstate the interface
again.

If no break occurred, the index equals config->desc.bNumInterfaces. A
subsequent usb_control_msg() failure resulted in a read from
config->interface[config->desc.bNumInterfaces] at label reset_old_alts.

In either case the last interface should be skipped.

Subject: USB: tty: Prune uses of tty_request_room in the USB layer

We have lots of callers that do not need to do this in the first place.
Remove the calls as they both cost CPU and for big buffers can mess up the
multi-page allocation avoidance.

Subject: USB: remove references to port->port.count from the serial drivers

This patch (as1344) removes references to port->port.count from the
USB serial drivers.  Now that serial ports are properly reference
counted, port.count checking is unnecessary and incorrect.  Drivers
should assume that the port is in use from the time the open method
runs until the close method is called.

Subject: USB: serial: ftdi: add CONTEC vendor and product id

This is a patch to ftdi_sio_ids.h and ftdi_sio.c that adds
identifiers for CONTEC USB serial converter. I tested it
with the device COM-1(USB)H

Subject: USB: usbmon: mask seconds properly in text API

The code does not implement the comment, so timestamps for long traces
become confusing instead of wrapping neatly as expected. This was actually
observed. Fortunately for API being in debugfs, we can just fix this instead
of staying bug-for-bug compatible. Double fortunately, the stable binary
API is not affected.

it's pretty clear the ID is theirs.

Subject: USB: pl2303: initial TIOCGSERIAL support

I've got a trivial patch for the pl2303 driver, that's what I needed to
make the wacom serial tablet driver work properly. It uses the
TIOCGSERIAL ioctl to determine if it's talking to a serial device or
not, which I gather is rather common, but the pl2303 driver didn't
implement that ioctl.

Here's a patch, I'm not sure it's absolutely correct, I mostly looked at
other similar usbserial drivers to see what I must do, but it works for
me.

Subject: USB: qcaux: driver for auxiliary serial ports on Qualcomm devices

qcaux: add driver for QCDM-capable ports on various devices

Many Qualcomm-based devices provide a CDC-ACM port which accepts
normal AT commands and PPP connections.  But they only provide one
which makes status or signal strength requests impossible while
PPP is active.  They also provide secondary USB interfaces that
talk the Qualcomm Diagnostic Monitor (QCDM) protocol which can be
used for status and strength.  Make those QCDM ports accessible.

Subject: pcmcia: disable pcmcia ioctl for !ARM, prepare for removal

The PCMCIA ioctl -- deprecated for years -- suffers from insufficient
locking. As it already has been deprecated for years, with its removal
long overdue, limit it to !SMP and !PREEMPT.

Furthermore, the last legitimate use of the ioctl to be reported
relates to the ARM architecture in 2008.[1] Attempts to resolve
this issue turned out unsuccessful so far.[2] Other usages have only
been reported as hear-say. If there are any legitiate and necessary
use-cases remaining, please speak out before the end of the grace
period until 2.6.3{5,6}(-rc1).

Subject: regulator: add voltage selection capability to mc13783 regulators v2
 .

This patch, complete the mc13783 regulator subsystem driver with
voltage selecting capability.
Main Switches (SW1AB, SW2AB) are not supported yet.

version 2 diffs:
- delete the "Switchers PLL" enable and multiplication factor value
  selecting capability because it is not a voltage or current regulator.
  This will be a part of Main switcher supporting task.
- Correct many coding style problems pointed me out.

Subject: regulator/lp3971: Storage class should be before const qualifier

The C99 specification states in section 6.11.5:

The placement of a storage-class specifier other than at the beginning
of the declaration specifiers in a declaration is an obsolescent
feature.

Subject: regulator: Add notifier event on regulator disable

The intended use case is for drivers which disable regulators to save
power but need to do some work to restore the hardware state when
restarting.  If the supplies are not actually disabled due to board
limits or sharing with other active devices this notifier allows the
driver to avoid unneeded reinitialisation, particularly when used with

Subject: regulator: Allow regulators to specify the time taken to ramp on
 enable

Regulators may sometimes take longer to enable than the control operation
used to do so, either because the regulator has ramp rate control used to
limit inrush current or because the control operation is very fast (GPIO
being the most common example of this).  In order to ensure that consumers
do not rely on the regulator before it is enabled provide an enable_time()
operation and have the core delay for that time before returning to the
caller.

This is implemented as a function since the ramp rate may be specified in
voltage per unit time and therefore the time depend on the configuration.
In future it would be desirable to allow the bulk operations to run the
delays for multiple enables in parallel but this is not currently supported.

Subject: regulator: mc13783: consider Power Gates as digital regulators.

GPO regulators are digital outputs that can be enabled or disabled by a
dedicated bit in mc13783 POWERMISC register.
In this family can be count in also Power Gates (PWGT1 and 2): enabled by
a dedicated pin a Power Gate is an hardware driven supply where the output
(PWGTnDRV) follow this law:

 Bit PWGTxSPIEN | Pin PWGTxEN | PWGTxDRV |  Read Back
   0 = default  |             |          | PWGTxSPIEN
 ---------------+-------------+----------+------------
       1        |      x      |   Low    |     0
       0        |      0      |   High   |     1
       0        |      1      |   Low    |     0

As read back value of control bit reflects the PWGTxDRV state (not the
control value previously written) and mc13783 POWERMISC register contain
only regulator related bits, a dedicated function to manage these bits is
created here with the aim of tracing the real value of PWGTxSPIEN bits
and reproduce it on next writes.

All POWERMISC users _must_ use the new function to not accidentally
disable Power Gates supplies.

v2 changes:
-Better utilization of abstraction layers.
-Voltage query support. GPO's and PWGTxDRV are fixed voltage regulator
 with voltage value of 3.1V and 5.5V respectively.

Subject: regulator: Assume regulators are enabled if they don't report
 anything

If a regulator driver does not provide a way to query if the driver is
enabled then assume that it is enabled.  This is very likely to reflect
the actual state is more useful for callers than reporting an error.

Subject: regulator: Provide optional dummy regulator for consumers

In order to ease transitions with drivers are boards start using regulators
provide an option to cause all regulator_get() calls to succeed, with a
dummy always on regulator being supplied where one has not been configured.
A warning is printed whenever the dummy regulator is used to aid system
development.

This regulator does not implement any regulator operations but will allow
simple consumers which only do enable() and disable() calls to run. It
is kept separate from the fixed voltage regulator to avoid Kconfig
confusion on the part of users when it is extended to allow boards to
explicitly use the dummy regulator to simplify cases where the majority
of supplies are from fixed regulators without software control.

This option is currently only effective for systems which do not specify
full constriants. If required an override could also be provided to allow
these systems to use the dummy regulator, though it is likely that
unconfigured supplies on such systems will lead to error due to
regulators being powered down more aggressively when not in use.

Subject: twl6030: regulator: Configure STATE register instead of REMAP

This is no REMAP register on twl6030, instead there is a STATE register
to drive a resource to a given state.
The state register can be used to specify what state the resource should
enter when its associated with a GRP.
Register Bit field description is as below. The patch programmes the
corresponding STATE registers for all LDO's to turn ON when assocaited
with GRP_P1.

STATE REG:
Bit7   |Bit6   |Bit5   |Bit4  |Bit3  |Bit2  |Bit1   |Bit0
P3_GRP |P2_GRP |P1_GRP |RES   |RES   |RES   |State1 |State0

State can be specified as below
00: OFF
01: ON
10: OFF
11: SLEEP

Subject: Regulators: virtual - use sysfs attribute groups

Instead of open-coding sysfs attribute group use canned solution.
Also add __devinit/__devexit markups for probe and remove methods
and use 'bool' where it makes sense.

Subject: Regulators: ab3100 - fix probe and remove annotations

Probe and remove methods should not be marked as __init/__exit but
rather __devinit/__devexit so that the needed sections stay in memory
in presence of CONFIG_HOTPLUG. This is needed even on non hotpluggable
buses.

Subject: Regulators: fixed - annotate probe and remove methods

Add __devinit/__devexit markings to probe and remove methids of the
driver, change types of variables containing boolean data to boolean,
set up driver's owner field so we have proper sysfs link between
driver and the module.

Subject: Regulators: lp3971 - fail if platform data was not supplied

There is no point in completing probe if platform data is missing so
let's abort loading early.

Also, use kcalloc when allocating several instances of the same data
structure and mark setup_regulators() as __devinit since it is only
called from lp3971_i2c_probe() which is __devinit.

regulator: wm8400 - cleanup platform driver data handling

Driver data set by platform_set_drvdata() is for private use of
the driver currently bound to teh device and not for use by parent,
subsystem and anyone else.

Subject: ioat3: cleanup, don't enable DCA completion writes

We already disallow raid operations while DCA is globally enabled, so
having it locally enabled is a nop and confusing when reading the code.

The pending == 2 case no longer exists in the driver so, we can use
ioat2_ring_pending() outside the lock to determine if there might be any
descriptors in the ring that the hardware has not seen.

Subject: kill unused invalidate_inode_pages helper

No one is calling this anymore as everyone has switched to
invalidate_mapping_pages long time ago.  Also update a few
references to it in comments.  nfs has two more, but I can't
easily figure what they are actually referring to, so I left
them as-is.

Subject: Staging: vme: Allow override of geographical address on tsi148

Geographical addressing only works if the VME backplane supports it. There
are a large number of old backplanes which do not support geographical
addressing. These boards will generally report a slot ID of zero - which is
an invalid ID in the slot numbering scheme.

Allow the geographical address to be over-ridden on the tsi148 so that a
slot ID can be provided manually in these circumstances.

Subject: Staging: rtl8187x: Use %pM for mac address output

Uncompiled.  Doesn't currently build anyway.

Converted MAC_FMT to %pM
Converted some %02x%02x%02x%02x%02x%02x to %pm
Converted MAC_ARG to direct use
Removed MAC_FMT and MAC_ARG macros

Subject: Staging: asus_oled: Add defines for asus vendor_id and device_id to
 be consistent with hid-ids.h

This almost trivial patch replaces the hardcoded values for the vendor and
device ids with defines, as they are used in drivers/hid/hid-ids.h

For me this seems to be more consistent, however as drivers/hid/hid-ids.h
is not within the default include directory I had to redefine the defines here
(maybe move the hid-ids.h to include/linux ?)

Subject: Staging: batman-adv: replace internal logging mechanism.

batman-adv used its own logging infrastructure. Replace this with
standard kernel logging, printk(), with compile time and runtime
options to enable/disable different debug levels.

+LOGGING/DEBUGGING
+-----------------
+
+All error messages, warnings and information messages are sent to the
+kernel log. Depending on your operating system distribution this can be
+read in one of a number of ways. Try using the commands: dmesg,
+logread, or looking in the files /var/log/kern.log or
+/var/log/syslog. All batman-adv messages are prefixed with
+"batman-adv:" So to see just these messages try
+
+dmesg | grep batman-adv
+
+When investigating problems with your mesh network it is sometimes
+necessary to see more detail debug messages. This must be enabled when
+compiling the batman-adv module. When building batman-adv as part of
+kernel, use "make menuconfig" and enable the option
+"B.A.T.M.A.N. debugging". When compiling outside of the kernel tree it
+is necessary to edit the file Makefile.kbuild and uncomment the line
+
+#EXTRA_CFLAGS += -DCONFIG_BATMAN_DEBUG
+
+The additional debug output is by default disabled. It can be enabled
+either at kernel modules load time or during run time. To enable debug
+output at module load time, add the module parameter debug=<value>.
+<value> can take one of four values.
+
+0 - All debug output disabled
+1 - Enable messages related to routing / flooding / broadcasting
+2 - Enable route or hna added / changed / deleted
+3 - Enable all messages
+
+e.g.
+
+modprobe batman-adv debug=2
+
+will load the module and enable debug messages for when routes or HNAs
+change.
+
+The debug output can also be changed at runtime using the file
+/sys/module/batman-adv/parameters/debug. e.g.
+
+echo 2 > /sys/module/batman-adv/parameters/debug
+
+enables debug messages for when routes or HNAs
+
+The debug output is sent to the kernel logs. So try dmesg, logread etc
+to see the debug messages.

From 4efe0b06559e8cb39c3d6a9bd01cc99604dfd247 Mon Sep 17 00:00:00 2001
From: Andrew Lunn <andrew@lunn.ch>
Date: Sat, 12 Dec 2009 23:39:42 +0100
Subject: Staging: batman-adv: Refactor routing.c

Break up a lot of the big functions up into many smaller ones. This
helps with readability and there is now a lot less code squashed
against the right hand margin.

Subject: Staging: batman-adv: stop persistent warnings if a device is
 deactivated.

Without this change we spam the kernel log on every packet received on
any other interface when an interface has been added, but is not yet
active, ie UP.

It does not matter if the interface is to be activated or not, we must
read the packet in order that it be discarded.

+The allocator shown here  exploits high memory. This document explains
+how  a user can  deal   with drivers uses   this  allocator and how  a
+programmer can link in the module.
+
+The module is being used by my pxc and pxdrv device drivers (as well as
+other ones), available from ftp.systemy.it/pub/develop and
+ftp.linux.it/pub/People/Rubini
+
+	User's manual
+	=============
+
+
+One of the most compelling problems with any DMA-capable device is the
+allocation  of a suitable  memory buffer. The "allocator" module tries
+to deal with  the problem in  a clean way.  The module is  able to use
+high   memory  (above the  one   used in  normal   operation)  for DMA
+allocation.
+
+To prevent  the  kernel for using   high memory,  so  that it  remains
+available for  DMA, you should  pass a  command  line argument to  the
+kernel.  Command line arguments  can be passed to  Lilo, to Loadlin or
+to whichever loader  you are using  (unless it's very poor in design).
+For Lilo, either use  "append=" in  /etc/lilo.conf or add  commandline
+arguments to the  interactive prompt. For  example, I have a 32MB  box
+and reserve two megs for DMA:
+
+In lilo.conf:
+	image = /zImage
+	label = linux
+	append = "mem=30M"
+
+Or, interactively:
+	LILO: linux mem=30M
+
+Once  the kernel is booted  with the  right command-line argument, any
+driver  linked   with  the  allocator   module  will  be able   to get
+DMA-capable memory without  much  trouble (unless the  various drivers
+need more memory than available).
+
+The module implements an alloc/free  mechanism,  so that it can  serve
+multiple drivers  at the  same time. Note  however that  the allocator
+uses all of  high memory and assumes to  be the only piece of software
+using such memory.
+
+
+	Programmer's manual
+	===================
+
+The allocator,  as  released, is designed  to  be linked  to  a device
+driver.  In this  case, the driver  must call allocator_init()  before
+using   the  allocator   and  must  call   allocator_cleanup()  before
+unloading.  This is  usually  done   from within  init_module()    and
+cleanup_module(). If the allocator is linked to  a driver, it won't be
+possible for several drivers to allocate high DMA memory, as explained
+above.
+
+It is possible, on the other hand, to compile the module as a standalone
+module, so that several modules can rely on the allocator for they DMA
+buffers. To compile the allocator as a standalone module, do the
+following in this directory (or provide a suitable Makefile, or edit
+the source code):
+
+	make allocator.o CC="gcc -Dallocator_init=init_module -Dallocator_cleanup=cleanup_module -include /usr/include/linux/module.h"
+
+The previous commandline  tells   to include <linux/module.h>  in  the
+first place,  and to rename the init  and cleanup function to the ones
+needed for  module loading and  unloading.  Drivers using a standalone
+allocator won't need to call allocator_init() nor allocator_cleanup().
+
+The allocator exports the following functions (declared in allocator.h):
+
+   unsigned long allocator_allocate_dma (unsigned long kilobytes,
+					 int priority);
+
+	This function returns a physical address, over high_memory,
+	which corresponds to an area of at least "kilobytes" kilobytes.
+	The area will be owned by the module calling the function.
+	The returned address can be passed to device boards, to instruct
+	their DMA controllers, via phys_to_bus(). The address can be used
+	by C code after vremap()/ioremap(). The "priority" argument should
+	be GFP_KERNEL or GFP_ATOMIC, according to the context of the
+	caller; it is used to call kmalloc(), as the allocator must keep
+	track of any region it gives away. In case of error the function
+	returns 0, and the caller is expected to issue a -ENOMEM error.
+
+
+   void allocator_free_dma (unsigned long address);
+
+	This function is the reverse of the previous one. If a driver
+	doesn't free the DMA memory it allocated, the allocator will
+	consider such memory as busy. Note, however, that
+	allocator_cleanup() calls kfree() on every region it reclaimed,
+	so that a driver with the allocator linked in can avoid calling
+	allocator_free_dma() at unload time.

+  02-Aug-2002 NJC         allocator now steps in 1MB increments, rather
+                          than doubling its size each time.
+			  Also, allocator_init(u_int *) now returns
+			  (in the first arg) the size of the free
+			  space.  This is no longer consistent with
+			  using the allocator as a module, and some changes
+			  may be necessary for that purpose.  This was
+			  designed to work with the DT3155 driver, in
+			  stand alone mode only!!!
+  26-Oct-2009 SS	  Port to 2.6.30 kernel.

+-- Changes --
+
+  Date     Programmer	Description of changes made
+  -------------------------------------------------------------------
+  03-Jul-2000 JML       n/a
+  10-Oct-2001 SS        port to 2.4 kernel
+  02-Apr-2002 SS        Mods to use allocator as a standalone module;
+                        Merged John Roll's changes (john@cfa.harvard.edu)
+                        to make work with multiple boards.
+  02-Jul-2002 SS        Merged James Rose's chages (rosejr@purdue.edu) to:
+                         * fix successive interrupt-driven captures
+                         * add select/poll support.
+  10-Jul-2002 GCS       Add error check when ndevices > MAXBOARDS.
+  02-Aug-2002 GCS       Fix field mode so that odd (lower) field is stored
+                        in lower half of buffer.
+  05-Aug-2005 SS        port to 2.6 kernel.
+  26-Oct-2009 SS	port to 2.6.30 kernel.
+
+-- Notes --
+
+** appended "mem=124" in lilo.conf to allow for 4megs free on my 128meg system.
+ * using allocator.c and allocator.h from o'reilly book (alessandro rubini)
+    ftp://ftp.systemy.it/pub/develop (see README.allocator)
+
+ + might want to get rid of MAXboards for allocating initial buffer.
+    confusing and not necessary
+
+ + in cleanup_module the MOD_IN_USE looks like it is check after it should
+
+ * GFP_DMA should not be set with a PCI system (pg 291)
+
+ - NJC why are only two buffers allowed? (see isr, approx line 358)

+  Date       Programmer  Description of changes made
+  -------------------------------------------------------------------
+  03-Jul-2000 JML       n/a
+  02-Apr-2002 SS        Mods to make work with separate allocator
+                        module; Merged John Roll's mods to make work with
+                        multiple boards.
+  10-Jul-2002 GCS       Complete rewrite of setup_buffers to disallow
+                        buffers which span a 4MB boundary.
+  24-Jul-2002 SS        GPL licence.
+  30-Jul-2002 NJC       Added support for buffer loop.
+  31-Jul-2002 NJC       Complete rewrite of buffer management
+  02-Aug-2002 NJC       Including slab.h instead of malloc.h (no warning).
+                        Also, allocator_init() now returns allocator_max
+                        so cleaned up allocate_buffers() accordingly.
+  08-Aug-2005 SS        port to 2.6 kernel.

Subject: Staging: udlfb: add dynamic modeset support
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add dynamic modeset support

udlfb uses EDID to find the monitor’s preferred mode
udlfb no longer has fixed mode tables – it’s able to set any mode
dynamically, from the standard VESA timing characteristics of the monitor.

Draws from probe and setmode code of both displaylink-mod 0.3 branch of
Roberto De Ioris, and Jaya Kumar's displaylinkfb.
Lays foundation for defio support and making backbuffer optional.
With additional changes to minimize diffs and clean for checkpatch.pl style.

Does not yet include new ioctls or refcount/mutex code from displaylink-mod.

Tested to work with existing xf-video-displaylink X server unmodified.

Date: Fri, 18 Dec 2009 15:52:53 -0800
Subject: Staging: s5k3e2fx.c: simplify complexity by factoring

the code was looping, setting s_move[i] to the following calculations

if (actual_step>= 0)
         s_move[i] = ((((i + 1) * gain + 0x200) - (i * gain + 0x200)) / 0x400);
else
         s_move[i] = ((((i + 1) * gain - 0x200) - (i * gain - 0x200)) / 0x400);

but, this code reduces to the expression
	s_move[i] = gain>>  10;

The reason for the complexity was to generate a step function with
integer division and rounding to land on specific values. But these calculations
can be simplified to the following code:

	gain = ((actual_step<<  10) / 5)>>  10;
	for (i = 0; i<= 4; i++)
		s_move[i] = gain;

Subject: Staging: rtl8192su: Build should select WIRELESS_EXT

The prevailing idiom is to select WIRELESS_EXT not depend on it.

Depending leaves this driver in a situation where it can only
be built if another driver that selects WIRELESS_EXT has been enabled.

Subject: staging: remove the b3dfg driver

It has no users, and no developers to maintain it to get
it merged into mainline.

So sad.

-DONE:
-    - functionality similar to logic testbench
-
-TODO:
-	- checkpatch.pl cleanups.
-	- keep state of DMA engines.
-	- keep data structure that keeps state of each transfer.
-	- interrupt handler should iterate over outstanding descriptor tables.
-	- complete userspace cdev to read/write using the DMA engines.
-	- split off the DMA support functions in a module, re-usable by custom
-	  drivers.

- * 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
- *
- *
- * Rationale: This driver exercises the chaining DMA read and write engine
- * in the reference design. It is meant as a complementary reference
- * driver that can be used for testing early designs as well as a basis to
- * write your custom driver.
- *
- * Status: Test results from Leon Woestenberg  <leon.woestenberg@axon.tv>:
- *
- * Sendero Board w/ Cyclone II EP2C35F672C6N, PX1011A PCIe x1 PHY on a
- * Dell Precision 370 PC, x86, kernel 2.6.20 from Ubuntu 7.04.
- *
- * Sendero Board w/ Cyclone II EP2C35F672C6N, PX1011A PCIe x1 PHY on a
- * Freescale MPC8313E-RDB board, PowerPC, 2.6.24 w/ Freescale patches.
- *
- * Driver tests passed with PCIe Compiler 8.1. With PCIe 8.0 the DMA
- * loopback test had reproducable compare errors. I assume a change
- * in the compiler or reference design, but could not find evidence nor
- * documentation on a change or fix in that direction.
- *
- * The reference design does not have readable locations and thus a
- * dummy read, used to flush PCI posted writes, cannot be performed.

From 7963eb432be2ebbf7e740bcdf6b385cc68fb7627 Mon Sep 17 00:00:00 2001
From: Jarod Wilson <jarod@redhat.com>
Date: Mon, 4 Jan 2010 18:02:27 -0500
Subject: staging: add Broadcom Crystal HD driver

This patch supersedes the earlier ones sent by Manu Abraham to add
the Broadcom Crystal HD driver to the staging tree, per discussion
with him about it. I've been working with Broadcom's Naren Sankar
on this driver for a number of months, and had already talked Naren
about submitting this on Broadcom's behalf, didn't expect anyone
else to jump on submitting it as quickly as Manu did. ;)

This version is a one-shot deal, incorporating the original driver,
Manu's coding style clean-ups, udev device creation support from
Edgar 'gimli' Hucek, and a number of other small tweaks from myself
and Scott Davilla, the other individual who has been working closely
on this code with Naren and I.

I've tested this iteration of the code lightly on a mini pci-e board
in a ThinkPad T61p running x86_64 Fedora 12, with the expected results,
and will test further on other systems with other variants of the card
(I have three varieties of this device currently in hand). Scott has
also tested on assorted primarily i686 varieties of Ubuntu, and Naren
has tested with both Fedora and Ubuntu, iirc.

Note: only the 70012 is currently supported by this driver, 70015
support will follow later. Also note that Blu-Ray support isn't
enabled (at the firmware level), due to misc fun related to the
BD encryption scheme, DRM, etc. :\

I *do* have a git tree containing the driver, lib, gst plugin and
firmware that I'm working from at the moment[*], as there are inter-
dependencies between the driver and lib, and the driver can be used
with kernels going a ways back (I've only tested back to 2.6.18 as
it exists in Red Hat Enterprise Linux 5). I'm exporting from there,
into a linux-next tree, then generating patches from there. The goal
is to feed everything upstream as quickly as possible, but there are
users who want this code for earlier kernels too...

The firmware will be submitted for inclusion in dwmw2's linux-firmware
tree once there is a suitable redistribution-no-modification type of
license on it (I believe Naren is working with Broadcom legal to get
that in place).

Changelog from initial Broadcom release to here:

    Unfortunately, we're unable to publicly publish all the history that got
    us from the initial internal code to what was released here, but such is
    life, we can just be happy we've got this open-sourced now. :)

From b6c359767bc743a7b6830660daa8f7e5c4273ad8 Mon Sep 17 00:00:00 2001
From: Simon Wunderlich <siwu@hrz.tu-chemnitz.de>
Date: Sat, 2 Jan 2010 11:30:39 +0100
Subject: Staging: batman-adv: initialize static hash iterators

instead of dynamically registering hash iterators, calling functions are
changed to register the iterator objects statically. The two advantages are:

 * no memory leaks when aborting from hash_iterate()
 * no calls to kmalloc/kfree, therefore a little faster/safer

Tested with 9 QEMU instances, no obvious regression found.

Subject: Staging: batman-adv: Use forw_bcast_list_lock always with disabled
 interrupts

forw_bcast_list_lock is spin_locked in both process and softirq context.
SoftIRQ calls the spinlock with disabled IRQ and normal process context
with enabled IRQs.

When process context is inside an spin_locked area protected by
forw_bcast_list_lock and gets interrupted by an IRQ, it could happen
that something tries to lock forw_bcast_list_lock again in SoftIRQ
context. It cannot proceed further since the lock is already taken
somewhere else, but no reschedule will happen inside the SoftIRQ
context. This leads to an complete kernel hang without any chance of
resurrection.

All functions called in process context must disable IRQs when they try
to get get that lock to to prevent any reschedule due to IRQs.

Subject: Staging: batman-adv: Fixes rounding issues in vis.c
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This patches fixes two rounding issues in vis.c for sending and
purging vis packets. Before, the timers and timeouts always got
rounded down to seconds, though we want a precision in
milliseconds.

This also fixes a kernel panic that occures when lowering the
timer for sending vis packets (vis_interval) to less than 1000ms
in main.c manually.

Subject: Staging: batman-adv: moving vis output formats out of the kernel

The batman-adv kernel module is able to output visualization data using the
dot draw or JSON format. This patch transforms the output into a generic
format (called vis raw). User space tool may convert the raw data to support
a variety of formats without the need of modifying the kernel module.

Subject: Staging: batman-adv: remove obsoleted vis_format /proc file

batman-adv used to export the vis data using different formats that were
switchable via /proc/net/batman-adv/vis_format. The various formats moved
to user space and rendered this configuration switch useless.

From e9b764506aeb06ada6a7d0a24eda3e6eb70bade1 Mon Sep 17 00:00:00 2001

Subject: Staging: batman-adv: splitting /proc vis file into vis_server and
 vis_data

The /proc vis file was used to enable/disable the vis server and to output
the vis data at the same time. This behaviour was confusing and lacked a
proper method to display the current vis server status.
This patch seperates the 2 functionalities:
* use vis_server to enable/disable the vis server and to retrieve its status
* use vis_data to retrieve the vis raw data (if the server is enabled)

Subject: Staging: batman-adv: check all kmalloc()s

there are some kmallocs left which are not checked whether they succeeds or
not, which might lead to corrupted data structures if the system memory is
full. This patch should clean up the remaining unchecked kmalloc()s.

From e70171957a3ac67fd62af0c66efe7b7749121899 Mon Sep 17 00:00:00 2001

Subject: Staging: batman-adv: receive packets directly using skbs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This patch removes the (ugly and racy) packet receiving thread and the
kernel socket usage. Instead, packets are received directly by registering
the ethernet type and handling skbs instead of self-allocated buffers.

Some consequences and comments:

 * we don't copy the payload data when forwarding/sending/receiving data
   anymore. This should boost performance.
 * packets from/to different interfaces can be (theoretically) processed
   simultaneously. Only the big originator hash lock might be in the way.
 * no more polling or sleeping/wakeup/scheduling issues when receiving
   packets
 * this might introduce new race conditions.
 * aggregation and vis code still use packet buffers and are not (yet)
   converted.
 * all spinlocks were converted to irqsave/restore versions to solve
   some lifelock issues when preempted. This might be overkill, some
   of these locks might be reverted later.
 * skb copies are only done if neccesary to avoid overhead

performance differences:

 * we made some "benchmarks" with intel laptops.
 * bandwidth on Gigabit Ethernet increased from ~500 MBit/s to ~920 MBit/s
 * ping latency decresed from ~2ms to ~0.2 ms

I did some tests on my 9 node qemu environment and could confirm that
usual sending/receiving, forwarding, vis, batctl ping etc works.

Subject: Staging: batman-adv: Allow the MAC address to be set

Some embedded devices have very limited sources of entropy for the
random number generator. It has been observed that the random MAC
address on the interface bat0 is not always random. When testing with
a collection of identical hardware, sometimes the bat0 device the same
MAC address on multiple devices, causing mayhem. This patch allows the
MAC address to be set by the user.

Subject: Staging: batman-adv: Use printk(%pM) for MAC addresses

printk() since kernel version 2.6.29 has supported printing MAC
addresses directly, as an extension to the %p processing. This patch
makes use of this for printk() and bat_dbg(). This will remove the
overhead of using addr_to_string() which is normally never actually
output.

Fixed a typo found by Gus Wirth.

Subject: Staging: batman-adv: Dont deactivate aggregation on wrong input
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A non-integer changes the aggregation mode. Therefore this patch changes
the behaviour to explicitly check strict_strtoul()'s return code.

Subject: Staging: hv: fix various coding style issues in RingBuffer.c

This is a patch to the RingBuffer.c file that corrects various coding style
warnings and errors found by checkpatch.pl

[ The real solution here is to get rid of this file entirely, and use the
kernel's internal ring buffer api, but until then, make these changes so as to
make checkpatch.pl happy, and keep others from continuously sending this type
of patch. - gkh]

Subject: Staging: hv: match on DMI values to know if we should run.

The HV core mucks around with specific irqs and other low-level stuff
and takes forever to determine that it really shouldn't be running on a
machine.  So instead, trigger off of the DMI system information and
error out much sooner.  This also allows the module loading tools to
recognize that this code should be loaded on this type of system.

Subject: Staging: rtl8192su, rtl8192u: use min_t() in store_debug_level()

sizeof() returns a size_t but the other types involved
are unsigned long, so using min() results in a warning.

As sizeof() is called on an 11 character buffer defined
immediately above unsigned long is obviously wide enough
for the result.

Subject: Staging: rtl8192su: buffer overflow in r8192U_core.c

There was a buffer overflow in the original code.  rf_path was 2 and it should
have been only 0 or 1.

I don't have the hardware for this, so I can't test it.

Looking at the code, there are two almost identical sections for updating the
hal variables.  The first one was clearly wrong and had the array overflow as
well.  The second one looked correct.  I decided to use the second section as
is except for whitespace changes.

The differences between the two original sections:
1)  The second one had more debug output.
2)  The second one looped over rf_path instead of corrupting data.

Without WEXT_PRIV set the driver fails to build due to unknown fields in

Subject: staging: crystalhd: add missing fixes for userspace lib build

I somehow managed to not actually include these two fixes in the submission
that was committed to the staging tree. libcrystalhd should eventually be
built against the kernel-provided header, and needs the stdint.h include. The
VOID bit is to keep things in sync with the Mac OS X driver and library that
Scott Davilla is also working on.

Subject: staging: crystalhd: trim register defines

We don't actually need most of the register defines to build,
and most of the ones we don't need aren't currently interesting.

We'll leave a full copy of all of them in libcrystalhd's source,
and only include what we need and/or think might be interesting
in the driver.

Subject: Staging: otus: Fix ZM_SEQ_DEBUG macro for no-debug case

tcp_seq is only initialised in case where ZM_ENABLE_PERFORMANCE_EVALUATION
is defined. So move the call to ZM_SEQ_DEBUG() and the decleration of
tcp_seq in there too.  This allows ZM_SEQ_DEBUG() to be removed from the
non-ZM_ENABLE_PERFORMANCE_EVALUATION case in the header file.

This resolves several compile warnings for the
non-ZM_ENABLE_PERFORMANCE_EVALUATION case.
However, the ZM_ENABLE_PERFORMANCE_EVALUATION
case seems to be completely broken.

A second smatch detected error. First part fixes in a typo
in the comment directly above that I noticed whilst trying
to remember what this code actually does. Second part is
the actual fix.  I'm fairly amazed this one never caused
trouble in testing as it is in one of the most common paths.

The id_table field of the struct pci_driver is constant in <linux/pci.h>
so it is worth to make the initialization data also constant.

The semantic match that finds this kind of pattern is as follows:

The id_table field of the struct usb_device_id is constant in <linux/usb.h>
so it is worth to make the initialization data also constant.

The semantic match that finds this kind of pattern is as follows:

Subject: Staging: ramzswap: Free memory when create_device is failed

If create_device is failed, it can't free gendisk and request_queue of
preceding devices. It cause memory leak.

This patch fixes it.

Subject: staging: wlags49: don't use custom implementation of atoi()

Kernel has its own method called simple_strtoul() to do such things.

Here we are using simple_strtoul(value, NULL, 0) because in original function
the recognized base is 10 or 16 and input data is assumed to be unsigned.

Subject: staging: sm7xx: remove the buggy 2D acceleration support

When scrolling the screen on the console with the 2D acceleration
support, the whole system may hang. for example, when copying some files
from another machine to YeeLoong netbook with the sm7xx video driver via
scp and when the screen output is enabled, the system may hang.

Before the bug is fixed, remove the 2D acceleration!

Subject: Staging: comedi: pcl818: Correct AI scan counting and channel checks

For AI commands, the scan counter should be updated after every
scan.  It was being updated after every sample except for DMA mode
where it was being updated after every repeated segment of the
channel list.

Also AI commands with multiple channels were being terminated with
an error prematurely except in DMA mode.  This was because the
driver was comparing channel numbers received from the hardware
(combined with the sample value) with the expected channel numbers
to check for a "channel dropout".  This test was failing
incorrectly because the driver was not keeping the current position
within the (repeated segment of the) channel list up to date.

Subject: Staging: comedi: adv_pci1710: Correct AI scan count and channel
 checks

For AI commands, the internal channel list used to check incoming
data was only set up partially if the channel list contained
repeats.  Set it up fully.  Also the current scan position was not
updated properly when moving a block of data from the FIFO unless
a whole number of scans was moved.

Subject: Staging: rt{2860,2870}sta: Use request_firmware() to load firmware

When originally introduced into staging, these drivers had custom
firmware-loading code which checked a version number and CRC at the
end of each blob.  This reintroduces those checks, using crc-ccitt
instead of custom code.

The removed firmware will be added to the linux-firmware.git
repository.

Based on work by Darren Salt <linux@youmustbejoking.demon.co.uk>.

I removed a misplace semicolon.  It is clear from the indentation that
TxPwrTracking87SE() was only supposed to be called if CheckTxPwrTracking()
returned true.

Subject: Staging: ramzswap: Use lock for 64-bit stats

64-bit stats corruption was observed when ramzswap was
used on SMP systems. To prevent this, use separate spinlock
to protect these stats.

Also, replace stat_*() with rzs_stat*() to avoid possible
conflict with core kernel code.

Eventually, these will be converted to per-cpu counters
if this driver finds use on large scale systems and this
locking is found to affect scalability.

ramzswap block size needs to be set equal to PAGE_SIZE to
avoid receiving any unaligned block I/O requests (happens
due to readahead logic during swapon). These unaligned
accesses produce unnecessary I/O errors, scaring users.

Subject: Staging: ramzswap: Return proper error code on device create failure

Currently, we return 0 if create_device() fails and 1 otherwise.
Now, proper error code is returned from create_device() and the
same is propagated as module error code from ramzswap_init().

Also added some cleanups for ramzswap_init(), improving function
structure.

Subject: Staging: ramzswap: Handle case for invalid backing swap

Currently, we crash (issue BUG_ON) if backing swap
disk size is zero. This can happen is user specified
an extended partition or simply a bad disk as backing
swap. A crash is really an unpleasant surprise to user
for such trivial problems.

Now, we check for this condition and simply fail device
initialization if this is the case.

Additional cleanups:
 * use static for all functions
 * remove extra newline between functions
 * memset backing_swap_name to NULL on device reset

Subject: Staging: mimio: remove the mimio driver

It turns out that Mimio has a userspace solution for this product using
libusb, and the in-kernel driver is just getting in the way now and
causing problems.  So they have asked that the in-kernel driver be
removed.  As the staging driver wasn't quite working anyway, and Mimio
supports their libusb solution for all distros, I am removing the
in-kernel driver.

The libusb solution can be downloaded from:
	http://www.mimio.com/downloads/mimio_studio_software/linux.asp

+	 * ======== The Lincroft Message Bus Interface ========

+	 *   3.  [15:8]: Register Offset

+	 *   5.  [3:0]: reserved
+	 *
+	 *  Read (0xD0) and write (0xE0) opcodes are written to the
+	 *  control register when reading and writing to Lincroft
+	 *  registers, respectively.
+	 *
+	 *  We're interested in registers found in the Lincroft

+	 *
+	 *  The six B-unit RAR register offsets we use are listed

Subject: Staging: r8187se: Remove two private variables that have a fixed
 value

For the RTL8187SE, the variable priv->rf_chip is always RF_ZEBRA4
and priv->RegThreeWireMode is always HW_THREE_WIRE_SI. Remove these
2 variables.

Subject: Staging: udlfb: pre-allocated urb list helpers

Add functions to pre-allocate and free usb bulk urbs for core render path.

Udlfb currently allocates a single urb, guarded by a mutex, that is a key
bottleneck. Because udlfb sends so much data, preallocation is most efficient.

Functions will be used by new rendering functions in later patches.

Subject: Staging: udlfb: clean up function naming

Move to more consistent naming scheme

All udlfb functions start with udlfb_
All functions for udlfb's fbdev interface start with udlfb_ops_
All functinos for udlfb's usb interface start with udlfb_usb_

From 7d9485e2c53caaaed9606a39de1c2746cc9ba262 Mon Sep 17 00:00:00 2001

Subject: Staging: udlfb: Add functions to expose sysfs metrics and controls

Add sysfs controls for edid and performance metrics

There are 8 new files exposed in /sys/class/graphics/fb*

edid - returns 128 byte edid blog, suitable for parsing with parse-edid
metrics_bytes_identical
metrics_bytes_rendered
metrics_bytes_sent
metrics_cpu_kcycles_used
metrics_misc
and metrics_reset, which resets all perf metrics to zero

The 6 perf metrics are of type atomic_t.
So these metrics return precise results for short benchmarks, but
any test approx a minute or longer runtime may roll over.

Subject: Staging: udlfb: Rework startup and teardown to fix race conditions

Rework probe to use refcounts and std functions

Because the different parts of the driver (usb, fbdev) tear down
in different orders, the driver previously could crash accessing
data that had already been freed.  Refcounting system used to handle.

Reworked probe to make use of refcounts, set mode using std fbops,
and set up sysfs and pre-allocated urbs.

From 530f43a8a69d9fa10ec6d30652244bb5e2a29694 Mon Sep 17 00:00:00 2001
From: Bernie Thompson <bernie@plugable.com>
Date: Mon, 15 Feb 2010 06:46:21 -0800
Subject: Staging: udlfb: improved rendering performance

Rework rendering for improved performance

Approx 10-20% gain avg across several "benchmarks": x11perf, gtkperf, glxgears
Moves from a single pre-alloc'd urb protected by a long-held mutex
To a list of (4) pre-alloc'd urbs which can be dispatched asynchonously

Improved rendering algorithm to hardware with lower CPU consumption,
fewer system memory accesses, and slightly higher compression.

Better scalability to multiple processors, especially with
multiple framebuffers active.

 /*
-Thanks to Henrik Bjerregaard Pedersen for rle implementation
-and code refactoring. Next step is huffman compression.
+Render a command stream for an encoded horizontal line segment of pixels.
+
+A command buffer holds several commands.
+It always begins with a fresh command header
+(the protocol doesn't require this, but we enforce it to allow
+multiple buffers to be potentially encoded and sent in parallel).
+A single command encodes one contiguous horizontal line of pixels
+
+The function relies on the client to do all allocation, so that
+rendering can be done directly to output buffers (e.g. USB URBs).
+The function fills the supplied command buffer, providing information
+on where it left off, so the client may call in again with additional
+buffers if the line will take several buffers to complete.
+
+A single command can transmit a maximum of 256 pixels,
+regardless of the compression ratio (protocol design limit).
+To the hardware, 0 for a size byte means 256
+
+Rather than 256 pixel commands which are either rl or raw encoded,
+the rlx command simply assumes alternating raw and rl spans within one cmd.
+This has a slightly larger header overhead, but produces more even results.
+It also processes all data (read and write) in a single pass.
+Performance benchmarks of common cases show it having just slightly better
+compression than 256 pixel raw -or- rle commands, with similar CPU consumpion.
+But for very rl friendly data, will compress not quite as well.

Subject: Staging: udlfb: Support for fbdev mmap clients (defio)

Add support for fbdev mmap clients who don't send damage ioctls

Because DisplayLink devices are out on the other end of usb, their
"framebuffer" is just normal system memory. So memory mapped writes
don't automatically trigger anything. So up to this point, standard
fbdev clients who rely on mmap() will get an unchanging screen.

This patch makes udlfb a client of Jaya Kumar's defio framework - which sets
up page fault triggers, and those faults are accumulated and sent to udlfb
on a defferred basis, to process as damage notifications for the framebuffer.

Because this involves more overhead than a notification directly from
the application (e.g. just passing on X DAMAGE extension notifications),
a sysfs attribute is provided by udlfb to control defio support.

/sys/class/graphics/fb*/use_defio - writing a "0" to this file before
calling mmap() causes defio to not be initialized - instead udlfb
will rely on getting damage notifications directly through the damage ioctl.

There are unsolved rendering problems with defio (horizontal dead regions
on framebuffer, that accumulate over time) which still needs a fix.

Subject: Staging: udlfb: explicit dependencies and warnings

Specify Kconfig dependencies, and include warnings for building as a module

udlfb is dependent on FB_DEFERRED_IO, FB_SYS_*, and FB_MODE_HELPERS

Because many kernels do not include defio (which cannot be built
as a module), yet users want to be able to build udlfb as a module later,
udlfb has ifdefs and these dependency warnings to help udlfb build with or
without certain dependencies, but also print warnings for any lost function.

Even though this kind of flexibility isn't common, we've gotten feedback
from a significant portion of users that they were frustrated without it.

-DMA Resource Allocation incomplete
-----------------------------------
-
-The current DMA resource Allocation provides no means of selecting the
-suitability of a DMA controller based on it's supported modes of operation, as
-opposed to the resource allocation mechanisms for master and slave windows:
-
-	struct vme_resource *vme_dma_request(struct device *dev);
-
-As opposed to:
-
-	struct vme_resource * vme_master_request(struct device *dev,
-		vme_address_t aspace, vme_cycle_t cycle, vme_width_t width);
-
-The TSI148 can perform, VME-to-PCI, PCI-to-VME, PATTERN-to-VME, PATTERN-to-PCI,
-VME-to-VME and PCI-to-PCI transfers. The CA91C142 can only provide VME-to-PCI
-and PCI-to-VME.
-
-Add a mechanism to select a VME controller based on source/target type,
-required aspace, cycle and width requirements.

Subject: Staging: vme: Enable drivers to handle more than one bridge

At the moment the vme bridge drivers are written in a way that only
allows them to support one bridge at a time. Modify the drivers to
enable more than one bridge to be present per board.

From 21e0cf6d2e59e19f77096e73d83157734e7f7782 Mon Sep 17 00:00:00 2001
From: Martyn Welch <martyn.welch@ge.com>
Date: Thu, 18 Feb 2010 15:13:32 +0000
Subject: Staging: vme: Correct ca91cx42 resource handling

The ca91cx42 driver currently incorrectly handles master windows, setting
and retrieving the sizing parameters incorrectly. Also, in the slave window
handling, it uses an incorrectly set variable.

Subject: Staging: vme: Use A24 when requesting slave resource

When requesting slave resources A16 addressing mode flag is used to find
available windows. Since the ca91cx42 bridge only supports two A16 slave windows
but four are requested, the driver fails to initialize. The flag has been
changed to A24, which is supported by all slave windows.

Subject: Staging: vme: Allocate memory buffers for master windows

For VME device I/O operations on master windows the user driver tends
to use kern_buf buffer array which is not allocated. This causes an error
when reading from master window device files.

VMIVME-7805 board has a special control register that has to be used in
order to activate the VME bus access via the Universe II bridge.
This control register also handles endianess convertion.

Subject: Staging: batman-adv: avoid having the same error message more than
 once

The routing code has 2 sections which warn about ttl exceeded. The
corresponding warnings were identical which makes it hard to debug. In
addition, batman-adv does not need to warn about ttl exceeded in case
we encountered an echo request as this is commonly used to generate
traceroute graphs.

Subject: Staging: batman-adv: atomic variable for vis-srv activation

This fixes the bug discovered by Marek Lindner which did not allow
turning on the vis-server before an interface has been added. With this
patch we are using a global atomic variable for activating and
deactiating the vis-server-mode, which can be used before
inserting an interface.

From e41a6f6d9cb7404420d596f27609a3f4f55dcaf5 Mon Sep 17 00:00:00 2001
From: Stewart Robertson <stewart_r@aliencamel.com>
Date: Sun, 21 Feb 2010 10:13:21 +0000
Subject: Staging: comedi: fix coding style issues in ni_labpc.c

This is a patch to the ni_labpc.c file that fixes the brace warnings and
comments over 80 characters found by the checkpatch.pl tool. Some code
still goes over 80 characters because I didn't know what to do with it.

This is a patch to the prism2usb.c that fixes one line which was over
the 80 character limit by wrapping it to a new line and removes a
commented out configuration for a ZyDAS ZD1201 device since support for
this device with this driver is now deprecated.

Subject: Staging: rtl8192su: fix for rtl819xU:Error TX URB for zero byte xxx,
 error -2

according to 'linux device drivers',
ENOENT, ECONNRESET, ESHUTDOWN are not real transmission errors.
also, a little cosmetics.

Subject: Staging: rtl8192su: re-enable tx-stats

currently, interface statistics look like this:

          RX bytes:456758 (446.0 Kb)  TX bytes:0 (0.0 b)

after re-enabling the tx-stats it looks like this:

From 3a8954e8f22cf31791d8c524c2839433e39f9368 Mon Sep 17 00:00:00 2001
From: H Hartley Sweeten <hartleys@visionengravers.com>
Date: Fri, 26 Feb 2010 17:58:07 -0700
Subject: staging: dt3155: revert u_long to u64 usage

Commit 9c1390a923ddb6fba1cf9d7440743369140c6d8a replaced
all u_int's with u32 and u_long's with u64. Unfortunately, a u_long
is still only 32-bits so they should have been replaced with u32 also.

This can be verified by the register definitions in dt3155_io.h.  It
specifically states that the memory mapped registers are 32-bit.

Fix this by changing all the u64 to u32.

Subject: ioat: close potential BUG_ON race in the descriptor cleanup path

Since ioat_cleanup_preamble() and the update of the last completed
descriptor are not synchronized there is a chance that two cleanup threads
can see descriptors to clean.  If the first cleans up all pending
descriptors then the second will trigger the BUG_ON.

Subject: ioat3: interrupt coalescing

The hardware automatically disables further interrupts after each event
until rearmed.  This allows a delay to be injected between the occurence
of the interrupt and the running of the cleanup routine.  The delay is
scaled by the descriptor backlog and then written to the INTRDELAY
register which specifies the number of microseconds to hold off
interrupt delivery after an interrupt event occurs.  According to
powertop this reduces the interrupt rate from ~5000 intr/s to ~150
intr/s per without affecting throughput (simple dd to a raid6 array).

Subject: ioat: cleanup ->timer_fn() and ->cleanup_fn() prototypes

If the calling convention of ->timer_fn() and ->cleanup_fn() are unified
across hardware versions we can drop parameters to ioat_init_channel() and
unify ioat_is_dma_complete() implementations.

Both ->timer_fn() and ->cleanup_fn() are modified to expect a struct
dma_chan pointer.

Subject: virtio: console: Use better variable names for fill_queue operation

We want to keep track of the number of buffers added to a vq. Use
nr_added_bufs instead of 'ret'.

Also, the users of fill_queue() overloaded a local 'err' variable to
check the numbers of buffers allocated. Use nr_added_bufs instead of
err.

Subject: dquot: cleanup dquot transfer routine

Get rid of the transfer dquot operation - it is now always called from
the filesystem and if a filesystem really needs it's own (which none
currently does) it can just call into it's own routine directly.

Rename the now static low-level dquot_transfer helper to __dquot_transfer
and vfs_dq_transfer to dquot_transfer to have a consistent namespace,
and make the new dquot_transfer return a normal negative errno value
which all callers expect.

Subject: hwmon: (lm90) Add SMBus alert support

Tested successfully with an ADM1032 chip on its evaluation board. It
should work fine with all other chips as well.

At this point this is more of a proof-of-concept, we don't do anything
terribly useful on SMBus alert: we simply log the event. But this could
later evolve into libsensors signaling so that user-space applications
can take an appropriate action.

Subject: hwmon: (it87) Display fan outputs in automatic mode as such

The it87 driver doesn't yet support automatic fan control. Let it at
least tell the user when a fan output is in automatic mode. Also let
the user switch from automatic mode (possibly set by the BIOS) to
manual mode and back without losing the settings.

Subject: hwmon: (it87) Expose the PWM/temperature mappings

Let the user read the PWM-to-temperature mappings. Until the trip
points are also exposed, this is essentially a way to know how the
BIOS has set things up. The ability to change the settings will be
added later, together with the trip points.

Subject: hwmon: (it87) Refactor attributes creation and removal

There is a lot of code redundancy in the creation of the fan and
pwm attributes. Move these attributes to arrays so that the code can
be simplified.

This in turns makes the attributes removal code larger, so move it to
a separate function that can be called in both the standard removal
case and the error path during probing.

Subject: hwmon: (it87) Create vid attributes by group

Only VID-related attributes are left in it87_attributes_opt, so we
might as well rename it to it87_attributes_vid and use this group to
create all attributes at once.

Subject: hwmon: (it87) Add support for beep on alarm

The IT87xxF chips support beeping on alarm, if properly wired and
configured. There is one control bit for each input type (temperature,
fan, voltage.) Let the user see and change them.

Subject: hwmon: (it87) Add support for old automatic fan speed control

Add support for the automatic fan speed control interface as
implemented by IT8705F chips up to revision F and IT8712F chips up to
revision G. This implementation fits very well in our standard sysfs
interface.

I implemented the old and not the new interface because the only chip
I have at hand is an old one, and the new interface is more difficult
to map to the standard sysfs interface. Adding support later should be
possible though, if someone with a supported chip is interested.

Subject: hwmon: (it87) Validate auto pwm settings

Before switching to automatic fan control mode, make sure that all the
trip points make sense. Otherwise, the control loop could lead to
weird fan behavior.

Subject: hwmon: (g760a) Make rpm_from_cnt static

Function rpm_from_cnt is only used internally so it can be made
static. Make it inline while we're here, for performance reasons
(although hopefully gcc would figure out by itself...)

From d84ca5b345c2b77ebf053d534ada6af2332a43b6 Mon Sep 17 00:00:00 2001
From: Wolfram Sang <w.sang@pengutronix.de>
Date: Fri, 5 Mar 2010 22:17:23 +0100
Subject: hwmon: Add driver for ADT7411 voltage and temperature sensor

Add basic support for the ADT7411. Reads out all conversion results (via I2C,
SPI yet missing) and allows some on-the-fly configuration. Tested with a
custom board.

Subject: hwmon: (tmp421) Restore missing inputs

An off-by-one error caused some inputs to not be created by the driver
when they should. TMP421 gets only one input instead of two, TMP422
gets two instead of three, etc. Fix the bug by listing explicitly the
number of inputs each device has.

Subject: hwmon: (tmp421) Fix temperature conversions

The low bits of temperature registers are status bits, they must be
masked out before converting the register values to temperatures.

Subject: PCI/PM Runtime: Make runtime PM of PCI devices inactive by default

Make the run-time power management of PCI devices be inactive by
default by calling pm_runtime_forbid() for each PCI device during its
initialization.  This setting may be overriden by the user space with
the help of the /sys/devices/.../power/control interface.

That's necessary to avoid breakage on systems where ACPI-based
wake-up is known to fail for some devices.

Subject: dm mpath: pass struct pgpath to pg init done

This patch removes some unnecessary argument casting. There is no
functional change with this patch.

Passes 'struct pgpath' through to pg_init_done() instead of the enclosed
'struct dm_path'.

Tested the changes with LSI storage..

Subject: dm mpath: skip activate_path for failed paths

This patch adds two minor fixes while processing device mapper path activation.

Skip failed paths while calling activate_path.  If the path is already failed
then activate_path will fail for sure. We don't have to call in that case. In
some case this might cause prolonged retries unnecessarily.

Change the misleading message if the path being activated fails with SCSI_DH_NOSYS.

Subject: dm table: remove dm_get from dm_table_get_md

Remove the dm_get() in dm_table_get_md() because dm_table_get_md() could
be called from presuspend/postsuspend, which are called while
mapped_device is in DMF_FREEING state, where dm_get() is not allowed.

Justification for that is the lifetime of both objects: As far as the
current dm design/implementation, mapped_device is never freed while
targets are doing something, because dm core waits for targets to become
quiet in dm_put() using presuspend/postsuspend.  So targets should be
able to touch mapped_device without holding reference count of the
mapped_device, and we should allow targets to touch mapped_device even
if it is in DMF_FREEING state.

Backgrounds:
I'm trying to remove the multipath internal queue, since dm core now has
a generic queue for request-based dm.  In the patch-set, the multipath
target wants to request dm core to start/stop queue.  One of such
start/stop requests can happen during postsuspend() while the target
waits for pg-init to complete, because the target stops queue when
starting pg-init and tries to restart it when completing pg-init.  Since
queue belongs to mapped_device, it involves calling dm_table_get_md()
and dm_put().  On the other hand, postsuspend() is called in dm_put()
for mapped_device which is in DMF_FREEING state, and that triggers
BUG_ON(DMF_FREEING) in the 2nd dm_put().

I had tried to solve this problem by changing only multipath not to
touch mapped_device which is in DMF_FREEING state, but I couldn't and I
came up with a question why we need dm_get() in dm_table_get_md().

Subject: dm mpath: hold io until all pg_inits completed

m->queue_io is set to block processing I/Os, and it needs to be kept
while pg-init, which issues multiple path activations, is in progress.
But m->queue is cleared when a path activation completes without error
in pg_init_done(), even while other path activations are in progress.
That may cause undesired -EIO on paths which are not complete activation.

This patch fixes that by not clearing m->queue_io until all path
activations complete.

(Before the hardware handlers were moved into the SCSI layer, pg_init
only used one path.)

When suspending the device we must wait for all I/O to complete, but
pg-init may be still in progress even after flushing the workqueue
for kmpath_handlerd in multipath_postsuspend.

This patch waits for pg-init completion correctly in
multipath_postsuspend().

Subject: dm raid1: always return error if all legs fail

If all mirror legs fail, always return an error instead of holding the
bio, even if the handle_errors option was set.  At present it is the
responsibility of the driver underneath us to deal with retries,
multipath etc.

The patch adds the bio to the failures list instead of holding it
directly.  do_failures tests first if all legs failed and, if so,
returns the bio with -EIO.  If any leg is still alive and handle_errors
is set, do_failures calls hold_bio.

Subject: dm: free dm_io before bio_endio not after

Free the dm_io structure before calling bio_endio() instead of after it,
to ensure that the io_pool containing it is not referenced after it is
freed.

This partially fixes a problem described here
  https://www.redhat.com/archives/dm-devel/2010-February/msg00109.html

thread 1:
bio_endio(bio, io_error);
/* scheduling happens */
					thread 2:
					close the device
					remove the device
thread 1:
free_io(md, io);

Thread 2, when removing the device, sees non-empty md->io_pool (because the
io hasn't been freed by thread 1 yet) and may crash with BUG in mempool_free.
Thread 1 may also crash, when freeing into a nonexisting mempool.

To fix this we must make sure that bio_endio() is the last call and
the md structure is not accessed afterwards.

There is another bio_endio in process_barrier, but it is called from the thread
and the thread is destroyed prior to freeing the mempools, so this call is
not affected by the bug.

A similar bug exists with module unloads - the module may be unloaded
immediately after bio_endio - but that is more difficult to fix.

Set a new DM_UEVENT_GENERATED_FLAG when returning from ioctls to
indicate that a uevent was actually generated.  This tells the userspace

Subject: dm raid1: fix deadlock when suspending failed device

To prevent deadlock, bios in the hold list should be flushed before
dm_rh_stop_recovery() is called in mirror_suspend().

The recovery can't start because there are pending bios and therefore
dm_rh_stop_recovery deadlocks.

When there are pending bios in the hold list, the recovery waits for
the completion of the bios after recovery_count is acquired.
The recovery_count is released when the recovery finished, however,
the bios in the hold list are processed after dm_rh_stop_recovery() in
mirror_presuspend(). dm_rh_stop_recovery() also acquires recovery_count,
then deadlock occurs.

+	  watchdog timer implemented in a external CPLD chip. Say Y here
+	  if you want to support for the watchdog timer on TS-72XX boards.
+
+	  To compile this driver as a module, choose M here: the
+	  module will be called ts72xx_wdt.

Subject: [WATCHDOG] iTCO_wdt: clean up probe(), modify err msg

It's possible that the platform is not allowing reboot via TCO timer
expiration.

Also, differentiate between not finding a chipset that has TCO, and the case
where TCO is present but the driver fails to initialize for some reason.

Subject: bitops: rename for_each_bit() to for_each_set_bit()

Rename for_each_bit to for_each_set_bit in the kernel source tree.  To
permit for_each_clear_bit(), should that ever be added.

The patch includes a macro to map the old for_each_bit() onto the new
for_each_set_bit().  This is a (very) temporary thing to ease the migration.

Subject: memory-hotplug: create /sys/firmware/memmap entry for new memory

A memmap is a directory in sysfs which includes 3 text files: start, end
and type.  For example:

start: 	0x100000
end:	0x7e7b1cff
type:	System RAM

Interface firmware_map_add was not called explicitly.  Remove it and add
function firmware_map_add_hotplug as hotplug interface of memmap.

Each memory entry has a memmap in sysfs, When we hot-add new memory, sysfs
does not export memmap entry for it.  We add a call in function add_memory
to function firmware_map_add_hotplug.

Add a new function add_sysfs_fw_map_entry() to create memmap entry, it
will be called when initialize memmap and hot-add memory.

Subject: drivers/misc/iwmc3200top/main.c: eliminate useless code

The variable priv is initialized twice to the same (side effect-free)
expression.  Drop one initialization.

A simplified version of the semantic match that finds this problem is:

Subject: lkdtm: add debugfs access and loosen KPROBE ties

Add adds a debugfs interface and additional failure modes to LKDTM to
provide similar functionality to the provoke-crash driver submitted here:

  http://lwn.net/Articles/371208/

Crashes can now be induced either through module parameters (as before)
or through the debugfs interface as in provoke-crash.

The patch also provides a new "direct" interface, where KPROBES are not
used, i.e., the crash is invoked directly upon write to the debugfs
file. When built without KPROBES configured, only this mode is available.

  * It is adapted from the Linux Kernel Dump Test Tool by
  * Fernando Luis Vazquez Cao <http://lkdtt.sourceforge.net>
  *
- * Usage :  insmod lkdtm.ko [recur_count={>0}] cpoint_name=<> cpoint_type=<>
- *							[cpoint_count={>0}]
+ * Debugfs support added by Simon Kagstrom <simon.kagstrom@netinsight.net>
  *
- * recur_count : Recursion level for the stack overflow test. Default is 10.
- *
- * cpoint_name : Crash point where the kernel is to be crashed. It can be
- *		 one of INT_HARDWARE_ENTRY, INT_HW_IRQ_EN, INT_TASKLET_ENTRY,
- *		 FS_DEVRW, MEM_SWAPOUT, TIMERADD, SCSI_DISPATCH_CMD,
- *		 IDE_CORE_CP
- *
- * cpoint_type : Indicates the action to be taken on hitting the crash point.
- *		 It can be one of PANIC, BUG, EXCEPTION, LOOP, OVERFLOW
- *
- * cpoint_count : Indicates the number of times the crash point is to be hit
- *		  to trigger an action. The default is 10.

Subject: ricoh_mmc: port from driver to pci quirk

This patch solves nasty problem original driver has.

Original goal of the ricoh_mmc was to disable this device because then,
mmc cards can be read using standard SDHCI controller, thus avoiding
writing of yet another driver.

However, the act of disablement, makes other pci functions that belong to
this controller (xD and memstick) shift up one level, thus pci core has
now wrong idea about these devices.

To fix this issue, this patch moves the driver into the pci quirk section,
thus it is executes before the pci is enumerated, and therefore solving
that issue, also same sequence of commands is performed on resume for same
reasons.

Also regardless of the above, this way is cleaner.  You still need to set
CONFIG_MMC_RICOH_MMC to enable this quirk

- * This is a conceptually ridiculous driver, but it is required by the way
- * the Ricoh multi-function chips (R5CXXX) work. These chips implement
- * the four main memory card controllers (SD, MMC, MS, xD) and one or both
- * of cardbus or firewire. It happens that they implement SD and MMC
- * support as separate controllers (and PCI functions). The linux SDHCI
- * driver supports MMC cards but the chip detects MMC cards in hardware
- * and directs them to the MMC controller - so the SDHCI driver never sees
- * them. To get around this, we must disable the useless MMC controller.
- * At that point, the SDHCI controller will start seeing them. As a bonus,
- * a detection event occurs immediately, even if the MMC card is already
- * in the reader.
- *
- * It seems to be the case that the relevant PCI registers to deactivate the
- * MMC controller live on PCI function 0, which might be the cardbus controller
- * or the firewire controller, depending on the particular chip in question. As
- * such, it makes what this driver has to do unavoidably ugly. Such is life.

Subject: davinci: MMC: add support for 8bit MMC cards

Add support for 8bit MMC cards.  The controller data width is configurable
depending on the wires setting in the platform data structure.

MMC 8bit is tested on OMAPL137 and MMC 4bit is tested on OMAPL138 EVM.

The code to write the ADMA descriptor into memory is repeated several
times throughout sdhci_adma_table_pre, and thus should be moved into a
common function.  This will also be useful if the patch to make the write
more efficient is accepted.

Subject: sdhci: improve sdhci sdhci_set_adma_desc() code

sdhci_set_adma_desc() is using byte-writes to write data in a specified
order into memory.  Change to using __le16 for the two byte and __le32 for
the four byte cases and use the cpu_to_{le16,le32} to do the conversion
before writing.

This will reduce the size of the code and the number of writes as we no
longer need to chop the data up before writing.

As an example on ARM S3C64XX SoC, in little-endian configuration:

Subject: sdio: introduce API for special power management features

This patch series provides the core changes needed to allow SDIO cards to
remain powered and active while the host system is suspended, and let them
wake up the host system when needed.  This is used to implement
wake-on-lan with SDIO wireless cards at the moment.  Patches to add that
support to the libertas driver will be posted separately.

This patch:

Some SDIO cards have the ability to keep on running autonomously when the
host system is suspended, and wake it up when needed.  This however
requires that the host controller preserve power to the card, and
configure itself appropriately for wake-up.

There is however 4 layers of abstractions involved: the host controller
driver, the MMC core code, the SDIO card management code, and the actual
SDIO function driver.  To make things simple and manageable, host drivers
must advertise their PM capabilities with a feature bitmask, then function
drivers can query and set those features from their suspend method.  Then
each layer in the suspend call chain is expected to act upon those bits
accordingly.

Subject: sdio: don't use CMD[357] as part of a powered SDIO resume

Seen on a Marvell 8686 SDIO card and Via VX855 controller: we must avoid
sending CMD3/5/7 on a resume where power has been maintained, because the
8686 will refuse to respond to them and the MMC stack will give up on the
card.

Subject: sdio: kick the interrupt thread upon a resume

Some SDIO cards may suspend while keeping function interrupts active
especially in the powered suspend case.  Upon resume we need to kick the
SDIO interrupt thread to check for pending interrupts and to restart card
IRQ detection at the host controller level.

Subject: s3cmci: initialize default platform data no_wprotect and no_detect
 with 1

If no platform_data was givin to the device it's going to use it's default
platform data struct which has all fields initialized to zero.  As a
result the driver is going to try to request gpio0 both as write protect
and card detect pin.  Which of course will fail and makes the driver
unusable

Previously to the introduction of no_wprotect and no_detect the behavior
was to assume that if no platform data was given there is no write protect
or card detect pin.  This patch restores that behavior.

Subject: mmc: at91_mci: use DMA buffer for read

Convert the read to use the DMA buffer as well.  The old code was doing
double-buffering DMA with the PDC; no way to make it work.  Replace it
with a single-PDC approach.  It also simplify things removing the need for
a pre_dma_read() function.

Subject: mmc: at91_mci: enable large data blocks

This patch is setting some max_ variables for the IO elevator, so the
elevator will put requests for large data blocks to the driver.  This is
critical for

a) speed

and

b) wear leveling of the flash chip controller: Otherwise the controller
   will treat the SD card badly with millions of single 4 KByte write
   commands.  This will lead to a shorter life time for the SD cards.

According to the datasheets AT91SAM9261 does not support SDIO interrupts,
and AT91SAM9260/9263 have an erratum requiring 4bit mode while using slot
B for the interrupt to work.

Subject: mmc: at91_mci: introduce per-mci-revision conditional code

We used to manage features and differences on a per-cpu basis.  As several
cpus share the same mci revision, this patch aggregates cpus that have the
same IP revision in one defined constant.  We use the
at91mci_is_mci1rev2xx() funtion name not to mess with newer Atmel sd/mmc
IP called "MCI2".  _rev2 naming could have been confusing...

Subject: drivers/hwmon/adcxx.c: fix for single-channel ADCs

While testing an ADC121S021 in an embedded board with a S3C2142 SoC (ARM
core), I have found that the 'adcxx' driver does not handle correctly
single channel ADCs from this chip family.  For single channel chips you
must only issue one read transfer for correct measurement.

Subject: console: limit the range of VGACON_SOFT_SCROLLBACK_SIZE

BuraphaLinux reported that we will trigger a mm warning when we
CONFIG_VGACON_SOFT_SCROLLBACK_SIZE=65536, this is because mm cann't
allocate so many pages.  We should limit the range of
CONFIG_VGACON_SOFT_SCROLLBACK_SIZE, don't give a user any chance to
trigger that.

Subject: xen: add kconfig menu

Currently the xen support drivers are displayed in the main Device Drivers
menu of the config tools instead of in their own sub-menu, so move them to
their own sub-menu, like the rest of the driver world uses.

This keeps the main Device Drivers menu from becoming messy.

The driver for the mc13783 rtc needs to know if the TODA irq is pending.

Instead of tracking in the rtc driver if the irq is enabled provide that
information, too.

This is to protect from interrupt handlers using an unregistered rtc
device.

To assert that the reset irq is considered now before the rtc is
registered the corresponding status is checked before.

Subject: rtc-coh901331: fix braces in resume code

The else part of the if statement is indented but does not have braces
around it. It clearly should since it uses clk_enable and clk_disable
which are supposed to balance.

Subject: gpio: add driver for MAX7300 I2C GPIO extender

Add the MAX7300-I2C variant of the MAX7301-SPI version.  Both chips share
the same core logic, so the generic part of the in-kernel SPI-driver is
refactored into a generic part.  The I2C and SPI specific funtions are
then wrapped into seperate drivers picking up the generic part.

- *   - always clock in 16 clocks at once
- *   - at DOUT: D15 first, D0 last
- *   - D0..D7 contains the data from the first cycle

Subject: gpio: introduce gpio_request_one() and friends

gpio_request() without initial configuration of the GPIO is normally
useless, introduce gpio_request_one() together with GPIOF_ flags for
input/output direction and initial output level.

gpio_{request,free}_array() for multiple GPIOs.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Introduce support for triggering interrupts on both rising and falling
edge.

This feature requires version 3 or newer of the IP, a version check is
done when triggering on both edges is requested.

Subject: gpio: pca953x.c: add interrupt handling capability

Most of the GPIO expanders controlled by the pca953x driver are able to
report changes on the input pins through an *INT pin.

This patch implements the irq_chip functionality (edge detection only).

The driver has been tested on an Arcom Zeus.

Subject: gpio: cs5535-gpio: fix input direction

The cs5535-gpio driver's get() function was returning the output value.
This means that the GPIO pins would never work as an input, even if
configured as an input.

The driver should return the READ_BACK value, which is the sensed line
value.  To make that work when the direction is 'output', INPUT_ENABLE
needs to be set.

In addition, the driver was not disabling OUTPUT_ENABLE when the direction
is set to 'input'.  That would cause the GPIO to continue to drive the pin
if the direction was ever set to output.

This issue was noticed when attempting to use the gpiolib driver to read
an external input.  I had previously been using the char/cs5535-gpio
driver.

Subject: PM: Provide generic subsystem-level callbacks

There are subsystems whose power management callbacks only need to
invoke the callbacks provided by device drivers.  Still, their system
sleep PM callbacks should play well with the runtime PM callbacks,
so that devices suspended at run time can be left in that state for
a system sleep transition.

Provide a set of generic PM callbacks for such subsystems and
define convenience macros for populating dev_pm_ops structures.

Subject: usbfs: fix deadlock on 'usbfs_mutex', clean up poll

The caller of usbfs_conn_disc_event() in some cases (but not always)
already holds usbfs_mutex, so trying to protect the event counter with
that lock causes nasty deadlocks.

The problem was introduced by commit 554f76962d ("USB: Remove BKL from
poll()") when the BLK protection was turned into using the mutex instead.

So fix this by using an atomic variable instead.  And while we're at it,
get rid of the atrocious naming of said variable and the waitqueue it is
associated with.

This also cleans up the unnecessary locking in the poll routine, since
the whole point of how the pollwait table works is that you can just add
yourself to the waiting list, and then check the condition you're
waiting for afterwards - avoiding all races.

It also gets rid of the unnecessary dynamic allocation of the device
status that just contained a single word.  We should use f_version for
this, as Dmitry Torokhov points out.  That simplifies everything
further.

Date: Sun, 7 Mar 2010 09:54:44 -0800
Subject: Revert "lib: build list_sort() only if needed"

This reverts commit a069c266ae5fdfbf5b4aecf2c672413aa33b2504.

It turns ou that not only was it missing a case (XFS) that needed it,
but perhaps more importantly, people sometimes want to enable new
modules that they hadn't had enabled before, and if such a module uses
list_sort(), it can't easily be inserted any more.

So rather than add a "select LIST_SORT" to the XFS case, just leave it
compiled in.  It's not all _that_ big, after all, and the inconvenience
isn't worth it.

Subject: mfd: Correct use after free for t7l66xb

The structure t7l66xb should not be freed before the subsequent references
to its fields in the arguments to clk_put.  Furthermore, this structure is
allocated near the beginning of the function, and a goto to the label
err_noirq appears after a successful allocation, so it would seem that the
kfree should be moved down below this label.

A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)

Subject: rtc: Suppress duplicate enable/disable of WM8350 update interrupt

Unlike the wm8350-custom code genirq nests enable and disable calls
so we can't just unconditionally mask or unmask the interrupt,
we need to remember the state we set and only mask or unmask when
there is a real change.

Subject: mfd: Convert WM8350 to genirq

This gives us use of the diagnostic facilities genirq provides and
will allow implementation of interrupt support for the WM8350 GPIOs.
Stub functions are provided to ease the transition of the individual
drivers, probably after additional work to pass the IRQ numbers via
the struct devices.

Subject: mfd: Don't allow WM8350 to be built modular

The genirq implementation does not allow modules to implement irq_chips
so the conversion of WM8350 to genirq means we can no longer allow the
driver to be built as a module.

The headphone detect and charger are using the IRQ numbers so need
to take account of irq_base with the genirq conversion. I obviously
picked the wrong system for initial testing.

Subject: mfd: Convert AB3100 driver to threaded IRQ

This converts the AB3100 core MFD driver to use a threaded
interrupt handler instead of the explicit top/bottom-half
construction with a workqueue. This saves some code and make it
more similar to other modern MFD drivers.

From 53dbab7af9ca13fa95605e9a5c31bb803dcba363 Mon Sep 17 00:00:00 2001
From: Haojian Zhuang <haojian.zhuang@marvell.com>
Date: Fri, 8 Jan 2010 06:01:24 -0500
Subject: mfd: Support 88pm8606 in 860x driver

88PM8606 and 88PM8607 are two discrete chips used for power management.
Hardware designer can use them together or only one of them according to
requirement.

There's some logic tightly linked between these two chips. For example, USB
charger driver needs to access both chips by I2C interface.

Now share one driver to these two devices. Only one I2C client is identified
in platform init data. If another chip is also used, user should mark it in
companion_addr field of platform init data. Then driver could create another
I2C client for the companion chip.

All I2C operations are accessed by 860x-i2c driver. In order to support both
I2C client address, the read/write API is changed in below.

reg_read(client, offset)
reg_write(client, offset, data)

The benefit is that client drivers only need one kind of read/write API. I2C
and MFD driver can be shared in both 8606 and 8607.

Since API is changed, update API in 8607 regulator driver.

Subject: mfd: Add irq support in 88pm860x

88PM860x is a complex PMIC device. It contains touch, charger, sound, rtc,
backlight, led, and so on.

Host communicates to 88PM860x by I2C bus. Use thread irq to support this
usage case.

Subject: regulator: Unsupport 88pm8607 A0 and A1

Remove the support 88PM8607 A0/A1 stepping. There's some register
definition changes in B0 stepping. It can make software more efficient.

From 6048a3dd2371c58611ea0ab8b306f8f1469399ae Mon Sep 17 00:00:00 2001
From: Cory Maccarrone <darkstar6262@gmail.com>

Subject: mfd: Add HTCPLD driver

This change introduces a driver for the HTC PLD chip found
on some smartphones, such as the HTC Wizard and HTC Herald.
It works through the I2C bus and acts as a GPIO extender.
Specifically:

 * it can have several sub-devices, each with its own I2C
   address
 * Each sub-device provides 8 output and 8 input pins
 * The chip attaches to one GPIO to signal when any of the
   input GPIOs change -- at which point all chips must be
   scanned for changes

This driver implements the GPIOs throught the kernel's
GPIO and IRQ framework.  This allows any GPIO-servicing
drivers to operate on htcpld pins, such as the gpio-keys
and gpio-leds drivers.

Subject: mfd: Use AB3100 MFD core IRQ for interrupt randomness

This reintroduces the entropy sampling of the AB3100 IRQ as the
IRQF_SAMPLE_RANDOM is going out according to the feature removal
schedule. I'm trying to do this the right way then, so CC:ing some
random people for a quick review. We add entropy for interrupt
events in the AB3100 which are truly random in nature, like
external cables being connected, voltages on batteries dropping
below certain ranges, ADC triggers or overheating.

This fixes the aged and unreachable debugfs code in the AB3100
OTP driver so that it's (A) reachable and (B) works. Bug detected
in parallell by Christoph Egger using VAMOS and Robert P. J. Day
by his kernel scanning script.

Subject: mfd: Remove leftover from discontinued TWL4030 battery patch

The TWL4030_BCI_BATTERY config option originates from a patch to the
omap git tree. However inclusion in linux was seemingly rejected and
the functionality nears inclusion under a different name so this
removes the bits of the old version that made it into the mainline
kernel again.

The WM8994 is a highly integrated ultra low power audio hub CODEC.
Since it includes on-board regulators and GPIOs it is represented
as a multi-function device, though the overwhelming majority of
the functionality is provided by the ASoC CODEC driver.

Subject: mfd: Use genirq in 88pm860x

Use genirq to simplify IRQ handling in 88pm860x. Remove the interface of
mask/free IRQs on 88pm860x. All these work is taken by genirq. Update the
touchscreen driver of 88pm860x since IRQ handling is changed.

Subject: mfd: Disable TWL4030/5030 I2C1/I2C4 internal pull-ups

This patch disables TWL4030/5030 I2C1 adn I2C4(SR) internal pull-up, to
use only the external HW resistor >=470 Ohm for the assured
functionality in HS mode.

While testing the I2C in High Speed mode, it was discovered that
without a proper pull-up resistor, there is data corruption during
multi-byte transfer. RTC(time_set) test case was used for testing.

From the analysis done, it was concluded that ideally we need a
pull-up of 1.6k Ohm(recomended) or atleast 470 Ohm or greater for
assured performance in HS mode.

Subject: tmio_mmc: Use 100ms mmc_detect_change() delay

This patch changes the tmio_mmc driver to wait 100ms
before checking the card detect status. This type of
delay is quite common among mmc drivers, it seems that
most hardware platforms need to give the hardware some
time to settle before checking card availabilty.

Hotplug is half-broken without this patch on the sh7724
Ecovec board. Hot insertion seems ok but eject is never
detected without this patch.

Subject: mfd: Add WM831x revision B support

Revision B of the WM831x devices changes the sense of the tristate
bit for GPIO configuration, inverting it to become an enable instead.
Take account of this in the gpiolib driver.

A current sink regulation status bit has also been added in revision B,
add a flag indicating if it's present but don't use it yet.

This revision also adds an interrupt on key up for the ON pin event
which the existing code is able to take advantage of.

Subject: mfd: Introduce remove_script function for twl4030

New function twl4030_remove_script(u8 flags) takes a script type as
defined in twl.h and prevents any script already loaded in that position
from running.  This is accomplished by programming SEQ_ADD_* to 0x3f,
the END_OF_SCRIPT value, where SEQ_ADD_* is determined by flags.

(Future) users of this function include OMAP board files for machines
facing a race condition between sleep and warm reset.

Subject: mfd: Use completion interrupt for WM835x AUXADC

Use the completion interrupt generated by the device rather than
polling for conversions to complete. As a backup we still check
the state of the AUXADC if we don't get a completion, mostly for
systems that don't have the WM8350 interrupt infrastructure hooked
up.

polling for conversions to complete. As a backup we still check
the status of the AUXADC if we don't get a completion, mostly for
systems that don't have the WM831x interrupt infrastructure hooked
up.

Also reduce the timeout for completion of conversions to 5ms from
the previous 10ms, the lower timeout should be sufficient.

Subject: mfd: Fix lpc_sch related depends/selects, fix build error

LPC_SCH is selected by GPI_SCH and I2C_ISCH, even when PCI is not
enabled, but LPC_SCH depends on PCI, so make GPI_SCH and I2C_ISCH
also depend on PCI.

Those 2 selects also need to select what LPC_SCH selects,
since kconfig does not follow selects.

+ * @num_msgs - Number of messages to be executed
+ *
+ * This is the function called by the generic kernel i2c_transfer()
+ * or i2c_smbus...() API calls. Note that this code is protected by the
+ * semaphore set in the kernel i2c_transfer() function.
+ *
+ * NOTE:
+ * READ TRANSFER : We impose a restriction of the first message to be the
+ * 		index message for any read transaction.
+ * 		- a no index is coded as '0',
+ * 		- 2byte big endian index is coded as '3'
+ * 		!!! msg[0].buf holds the actual index.
+ * 		This is compatible with generic messages of smbus emulator
+ * 		that send a one byte index.
+ * 		eg. a I2C transation to read 2 bytes from index 0
+ *			idx = 0;
+ *			msg[0].addr = client->addr;
+ *			msg[0].flags = 0x0;
+ *			msg[0].len = 1;

+ *			msg[1].addr = client->addr;
+ *			msg[1].flags = I2C_M_RD;
+ *			msg[1].len = 2;
+ *			msg[1].buf = rd_buff
+ *			i2c_transfer(adap, msg, 2);
+ *
+ * WRITE TRANSFER : The I2C standard interface interprets all data as payload.
+ *		If you want to emulate an SMBUS write transaction put the
+ *		index as first byte(or first and second) in the payload.
+ *		eg. a I2C transation to write 2 bytes from index 1
+ *			wr_buff[0] = 0x1;
+ *			wr_buff[1] = 0x23;
+ *			wr_buff[2] = 0x46;
+ *			msg[0].flags = 0x0;
+ *			msg[0].len = 3;
+ *			msg[0].buf = wr_buff;
+ *			i2c_transfer(adap, msg, 1);
+ *
+ * To read or write a block of data (multiple bytes) using SMBUS emulation

Subject: i2c/imx: don't add probe function to the driver struct
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Having a pointer to the probe function is unnecessary when using
platform_driver_probe and yields a section mismatch warning after
removing the white list entry "*driver" for
{ .data$, .data.rel$ } -> { .init.* } mismatches in modpost.

Subject: i2c-mpc: use __devinit[data] for initialization functions and data

"__devinit[data]" has not yet been used for all initialization functions
and data. To avoid truncating lines, the struct "mpc_i2c_match_data" has
been renamed to "mpc_i2c_data", which is even the better name.

Subject: i2c-mpc: add support for the MPC512x processors from Freescale

As I2C interrupts must  be enabled for the MPC512x by the setup function
as well, "fsl,preserve-clocking" is handled in a slighly different way.
Also, the old settings are now reported calling dev_dbg(). For the
MPC512x the clock setup function of the MPC52xx can be re-used.
Furthermore, the Kconfig help has been updated and corrected.

Subject: i2c-pnx: fix setting start/stop condition

The start/stop condtions are set in different places repetedly in the i2c-pnx
driver.  Beside in i2c_pnx_start and i2c_pnx_stop the start/stop bit are also
set during the transfer of a i2c message in the master_xmit/rcv calls. This is
wrong since we can't set the start/stop condition during the transaction of a
single message any way. As a matter of fact, the driver will sometimes set both
the start and the stop bits at one time. This can be easily reproduced by
sending a simple read request like e.g
struct i2c_msg msgs[] = {
{ addr, 0, 1, buf },
{ addr, I2C_M_RD, offset, buf }
};
While processing the first message the i2c_pnx_master_xmit will set both the
start_bit and the stop_bit, which will eventually confuse the slave.

Fixed by remove setting start/stop condition from the transmit routines.

Subject: i2c: omap: Add support for 16-bit registers

The current i2c-omap driver is set up for 32-bit registers, which
corresponds to most OMAP devices.  However, OMAP730/850 based
devices use a 16-bit register size.

This change modifies the driver to perform a runtime CPU type check
to determine the register sizes, and uses a bit shift of either 1
or 2 bits to compute the proper register sizes for all registers.

Content-Transfer-Encoding: 8bit

This patch adds support for the Xilinx XPS IIC Bus Interface.

The driver uses the dynamic mode, supporting to put several
I2C messages in the FIFO to reduce the number of interrupts.

It has the same feature as ocores, it can be passed a list
of devices that will be added when the bus is probed.

The problem is that kobject_add_internal() first adds a kobject to the
kset and then try to create sysfs directory for it.  If the creation
fails, it remove the kobject from the kset.  get_device_parent()
accesses class_dirs kset while only holding class_dirs.list_lock to
see whether the cuse class dir exists.  But when it exists, it may not
have finished initialization yet or may fail and get removed soon.  In
the above case, the former happened so the second one ends up trying
to create subdirectory under NULL sysfs_dirent.

Fix it by grabbing a mutex in get_device_parent().

Subject: Driver core: add platform_create_bundle() helper

Many legacy-style module create singleton platform devices themselves,
along with corresponding platform driver. Instead of replicating error
handling code in all such drivers, provide a helper that allocates and
registers a single platform device and a driver and binds them together.

Subject: sysdev: Pass attribute in sysdev_class attributes show/store

Passing the attribute to the low level IO functions allows all kinds
of cleanups, by sharing low level IO code without requiring
an own function for every piece of data.

Also drivers can extend the attributes with own data fields
and use that in the low level function.

Similar to sysdev_attributes and normal attributes.

This is a tree-wide sweep, converting everything in one go.

No functional changes in this patch other than passing the new
argument everywhere.

Tested on x86, the non x86 parts are uncompiled.

Subject: sysfs: Add attribute array to sysdev classes

Add a attribute array that is automatically registered and unregistered
to struct sysdev_class. This is similar to what struct class has.

A lot of drivers add list of attributes, so it's better to do
this easily in the common sysdev layer.

This adds a new field to struct sysdev_class. I audited the
whole tree and there are no dynamically allocated sysdev classes,
so this is fully compatible.

Subject: driver-core: Add attribute argument to class_attribute show/store

Passing the attribute to the low level IO functions allows all kinds
of cleanups, by sharing low level IO code without requiring
an own function for every piece of data.

Also drivers can extend the attributes with own data fields
and use that in the low level function.

This makes the class attributes the same as sysdev_class attributes
and plain attributes.

This will allow further cleanups in drivers.

Full tree sweep converting all users.

Subject: driver core: Add class_attr_string for simple read-only string

Several drivers just export a static string as class attributes.

Use the new extensible attribute support to define a simple
CLASS_ATTR_STRING() macro for this.

This will allow to remove code from drivers in followon patches.

Convert some drivers who export a single string as class attribute
to the new class_attr_string functions. This removes redundant
code all over.

Subject: Driver-Core: devtmpfs - reset inode permissions before unlinking

Before unlinking the inode, reset the current permissions of possible
references like hardlinks, so granted permissions can not be retained
across the device lifetime by creating hardlinks, in the unusual case
that there is a user-writable directory on the same filesystem.

Subject: kobject: Constify struct kset_uevent_ops

Constify struct kset_uevent_ops.

This is part of the ops structure constification
effort started by Arjan van de Ven et al.

Benefits of this constification:

 * prevents modification of data that is shared
   (referenced) by many other structure instances
   at runtime

 * detects/prevents accidental (but not intentional)
   modification attempts on archs that enforce
   read-only kernel data at runtime

 * potentially better optimized code as the compiler
   can assume that the const data cannot be changed

 * the compiler/linker move const data into .rodata
   and therefore exclude them from false sharing

Subject: platform-drivers: move probe to .devinit.text in drivers/scsi
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A pointer to a probe callback is passed to the core via
platform_driver_register and so the function must not disappear when the
.init sections are discarded.  Otherwise (if also having HOTPLUG=y)
unbinding and binding a device to the driver via sysfs will result in an
oops as does a device being registered late.

An alternative to this patch is using platform_driver_probe instead of
platform_driver_register plus removing the pointer to the probe function
from the struct platform_driver.

Subject: platform-drivers: move probe to .devinit.text in drivers/video
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A pointer to a probe callback is passed to the core via
platform_driver_register and so the function must not disappear when the
.init sections are discarded.  Otherwise (if also having HOTPLUG=y)
unbinding and binding a device to the driver via sysfs will result in an
oops as does a device being registered late.

An alternative to this patch is using platform_driver_probe instead of
platform_driver_register plus removing the pointer to the probe function
from the struct platform_driver.

Subject: x86: move hp-wmi's probe function to .devinit.text
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A pointer to hp_wmi_bios_setup is passed to the core via
platform_driver_register and so the function must not disappear when the
.init sections are discarded.  Otherwise (if also having HOTPLUG=y)
unbinding and binding a device to the driver via sysfs will result in an
oops as does a device being registered late.

An alternative to this patch is using platform_driver_probe instead of
platform_driver_register plus removing the pointer to the probe function
from the struct platform_driver.

Subject: media: move omap24xxcam's probe function to .devinit.text
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A pointer to omap24xxcam_probe is passed to the core via
platform_driver_register and so the function must not disappear when the
.init sections are discarded.  Otherwise (if also having HOTPLUG=y)
unbinding and binding a device to the driver via sysfs will result in an
oops as does a device being registered late.

An alternative to this patch is using platform_driver_probe instead of
platform_driver_register plus removing the pointer to the probe function
from the struct platform_driver.

Subject: UIO: Add a driver for Hilscher netX-based fieldbus cards

This patch adds a Userspace IO driver for netX-based fieldbus cards by
Hilscher (see http://www.hilscher.com). ATM, cifX and comX cards are
supported. The userspace part for this driver is provided by Hilscher
and should come with the card.
The driver is in use for several months now and has been tested by
people at Hilscher and Linutronix.

Two trivial fixes for the Userspace IO Kconfig file:
1) uio_sercos3 is a PCI driver, so let it depend on PCI.
2) "default n" under UIO_PCI_GENERIC is luxury since it is already the default.

Subject: UIO: Remove SMX Cryptengine driver

Ben Nizette, the author of this driver, told me in a private mail that this
project has been cancelled. He suggested to remove the driver for now, and
will come back with a new version should the hardware really exist.
This patch completely removes the driver.

Subject: sysfs: Use sysfs_attr_init and sysfs_bin_attr_init on dynamic
 attributes

These are the non-static sysfs attributes that exist on
my test machine.  Fix them to use sysfs_attr_init or
sysfs_bin_attr_init as appropriate.   It simply requires
making a sysfs attribute present to see this.  So this
is a little bit tedious but otherwise not too bad.

Subject: Driver core: create lock/unlock functions for struct device

In the future, we are going to be changing the lock type for struct
device (once we get the lockdep infrastructure properly worked out)  To
make that changeover easier, and to possibly burry the lock in a
different part of struct device, let's create some functions to lock and
unlock a device so that no out-of-core code needs to be changed in the
future.

This patch creates the device_lock/unlock/trylock() functions, and
converts all in-tree users to them.

Subject: msi-laptop: Support standard ec 66/62 command on MSI notebook and
 nebook

Suppport standard ec 66/62 command on MSI notebook and nebook. MSI
netbook and notebook already support 66/62 command, so, add new
get_state function, and put the old model to non-standard model, but
driver still support those old model.

Subject: msi-laptop: Support some MSI 3G netbook that is need load SCM

Some MSI 3G netbook only have one fn key to control Wlan/Bluetooth/3G,
those netbook will load the SCM (windows app) to disable the original
Wlan/Bluetooth control by BIOS when user press fn key, then control
Wlan/Bluetooth/3G by SCM (software control by OS). Without SCM, user
cann't on/off 3G module on those 3G netbook.
On Linux, msi-laptop driver will do the same thing to disable the
original BIOS control, then might need use HAL or other userland
application to do the software control that simulate with SCM.
e.g. MSI N034 netbook

Implement the resume method for set the load SCM flag after system reusme.
Without this patch, the wifi function key on SCM model will back to BIOS
control mode then confuse with the userland software control.
e.g. MSI N034

Before you can read or write from the i6300esb memeory mapped registers,
you need to unlock these. This is done by writing the magic numbers 0x80
and 0x86 to the reload register. The size of the reload register is 32bit
though.

Also binary 11 is hex 0x03 and not 0x11.

Subject: [S390] hvc_iucv: allocate memory buffers for IUCV in zone DMA

The device driver must allocate memory for IUCV buffers with GFP_DMA,
because IUCV cannot address memory above 2GB (31bit addresses only).

Because the IUCV ignores the higher bits of the address, sending and
receiving IUCV data with this driver might cause memory corruptions.

Subject: [S390] remove unused qdio flags in zfcp and qeth

zfcp and qeth are setting flags for the qdio-layer, but these flags
are not used in qdio. Patch removes the flag definitions from qdio
and their settings in zfcp and qeth.

Subject: [S390] dasd: automatic recognition of read-only devices

In z/VM it is possible to attach a device as read-only. To prevent
unintentional write requests and subsequent I/O errors, we can detect
this configuration using the z/VM DIAG 210 interface and set the
respective linux block device to read-only as well.

Subject: [S390] smsgiucv_app: deliver z/VM CP special messages (SMSG) as
 uevents

The smsgiucv_app driver registers a callback with the smsgiucv driver
to receive z/VM CP special messages (SMSG) starting with "APP".

When the callback is called for special messages, the driver creates
an uevent for the received message.  The uevent consists of additional
environment data containing the message prefix ("APP"), message sender,
and message content.

udev rules can be used to trigger application specific actions through
matching the content or sender of the special message.

Subject: [WATCHDOG] i6300esb.c: change platform_driver to pci_driver

Since the intel 6300esb platform uses a dedicated PCI ID for
it's watchdog timer (00:1d.4), it's better and easier to have
this as a pci_driver.

Subject: qlogicpti: Remove slash in QlogicPTI irq name

qlogicpti driver registers its irq with a name containing slash.
This results in

[   71.132815] name 'Qlogic/PTI'

because proc_mkdir with the name of the irq fails. Fix it by just
removing the slash from irq name. Discovered and tested on real hardware
(Sun Ultra 1).

Subject: ACPI / EC / PM: Close race between EC and resume from hibernation

There is a race between resume from hibernation and the EC driver
that may result in restoring the hibernation image in the middle of
an EC transaction in progress, which in turn may lead to
unpredictable behavior of the platform.

To remove that race condition, add a helpers for suspending and
resuming EC transactions in a safe way to be executed by the ACPI
platform hibernate pre-restore and restore cleanup callbacks.

Subject: Input: scancode in get/set_keycodes should be unsigned
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The HID layer has some scan codes of the form 0xffbc0000 for logitech
devices which do not work if scancode is typed as signed int, so we need
to switch to unsigned it instead. While at it keycode being signed does
not make much sense either.

Subject: Input: remove BKL, fix input_open_file() locking

Holding the BKL in input_open_file seems pointless because it does not
protect against updates of input_table, and all open functions from the
underlying drivers have proper mutex locking.

This makes input_open_file take the input_mutex when accessing
the table and no lock when calling into the lower function.

We need to use the nosync version of disable_irq so that we don't hang in

work regardless, but at some point, the IRQ behavior changed.  Not sure
when exactly.

The AD7873 is almost identical to the ADS7846; the only difference is
related to the Power Management bits PD0 and PD1.  This results in a
slightly different PENIRQ enable behavior.  For the AD7873, VREF should
be turned off during differential measurements.

So, add the AD7873/43 to the list of driver supported devices, and prevent
VREF usage during differential/ratiometric conversion modes.

Subject: Input: ad7877 - increase pen up imeout

The time interval between consecutive interrupts depends on a number of
tunables: first_conversion_delay, acquisition_time, averaging and foremost
the pen_down_acc_interval.

Since the mod_timer() action for the PEN UP event happens in the
spi_async() callback function, latencies incurred by the spi bus drivers
also need to be taken into account.

So all in all, give the PEN UP event a bit more wiggle room and increase
timeout to 100ms.

Subject: Input: appletouch - fix integer overflow issue

When reading data from Geyser 2 touchpads used on post Oct 2005 Apple
PowerBooks the driver was casting X and Y coordinates values to
'signed char'. Testing on one of such PowerBooks I have noticed that
touchpad always generates positive values, but some of them are greater
that 127, and thus, when cast to 'signed char' being interpreted as
a negative.

Such bigger values have been observed infrequently, closer to the
edges of a touchpad, so the problem was not very visible.
Nevertheless, the patch would potentially improve touchpad
driver accuracy.

Subject: Input: wm831x-on - convert to use genirq

Now that the WM831x core has been converted to use genirq for the
interrupt controller there is no need for the client drivers to
use a WM831x-specific API rather than just calling genirq directly.

Also fixes a leak of the IRQ during init failure - the error path
free_irq() was using NULL rather than the driver data as the data
pointer so free_irq() wouldn't have matched.

Subject: IPoIB: Fix TX queue lockup with mixed UD/CM traffic

The IPoIB UD QP reports send completions to priv->send_cq, which is
usually left unarmed; it only gets armed when the number of
outstanding send requests reaches the size of the TX queue. This
arming is done only in the send path for the UD QP.  However, when
sending CM packets, the net queue may be stopped for the same reasons
but no measures are taken to recover the UD path from a lockup.

Consider this scenario: a host sends high rate of both CM and UD
packets, with a TX queue length of N.  If at some time the number of
outstanding UD packets is more than N/2 and the overall outstanding
packets is N-1, and CM sends a packet (making the number of
outstanding sends equal N), the TX queue will be stopped.  When all
the CM packets complete, the number of outstanding packets will still
be higher than N/2 so the TX queue will not be restarted.

Fix this by calling ib_req_notify_cq() when the queue is stopped in
the CM path.

Subject: mfd: Several MFD drivers should depend on GENERIC_HARDIRQS

commit 5fb4d38b19d95a5f980f0a10adba798f5b92128c ("mfd: Move WM831x to
generic IRQ") didn't take into account that genirq support depends on
GENERIC_HARDIRQS.

Additionally, 2.6.34-rc1 added:
  - commit 2afa62ea76027b00e472ddb672191e6e15425b43 ("mfd: Use genirq in
    88pm860x").
  - commit 760e4518788df6762700e6bb9dd8692379f11168 ("mfd: Convert WM8350 to
    genirq").
  - commit 1f1cf8f98cf6588365efeaab8e7e7758aaa77f6e ("mfd: Update irq handler
    in max8925")

Make all of them depend on GENERIC_HARDIRQS to avoid compile errors on
architectures that don't support genirq yet.

Subject: RDMA/nes: Fix CX4 link problem in back-to-back configuration

Commit 09124e19 ("RDMA/nes: Add support for KR device id 0x0110") took
out too much code and broke CX4 link detection in back-to-back
configuration.  Put back the code that does the link check.

Subject: rtc/hctosys: only claim the RTC provided the system time if it did
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Without this patch /sys/class/rtc/$CONFIG_RTC_HCTOSYS_DEVICE/hctosys
contains a 1 (meaning "This rtc was used to initialize the system clock")
even if reading the time at bootup failed.

Moreover change error handling in rtc_hctosys() to use goto and so reduce
the indention level.

Subject: sdio: recognize io card without powercycle

SDIO Simplified Specification V2.00 states that it is strongly recommended
that the host executes either a power reset or issues a CMD52 (I/O Reset)
to re-initialize an I/O only card or the I/O portion of a combo card.
Additionally, the CMD52 must be issued first because it cannot be issued
after a CMD0.

With this patch the Nintendo Wii SDIO-based WLAN card is detected after a
system reset, without requiring a complete system powercycle.

Subject: drivers/scsi/ses.c: eliminate double free

The few lines below the kfree of hdr_buf may go to the label err_free
which will also free hdr_buf.  The most straightforward solution seems to
be to just move the kfree of hdr_buf after these gotos.

A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)

// <smpl>

Subject: drivers/block/floppy.c: remove unnecessary argument from

Prior to patch "drivers/block/floppy.c: Use pr_<level>" only
reschedule_timeout(,"request done"...) printed a numeric value after a
reschedule_timeout event message.

Restore that behavior and remove the now unnecessary argument.

Subject: fbdev: bf54x-lq043fb/bfin-t350mcqb-fb: drop custom mmap() handler

The common Blackfin code implements the get_fb_unmapped_area() function,
so we no longer need to have our own mmap() handler.  The common fb code
will take care of everything for us now.

Subject: broadsheetfb: add multiple panel type support

Update broadsheetfb to add support for multiple panel types.  The 3.7" and
6" are known to work but the 9.7" is untested due to lack of hardware.

Print a warning when viafb ioctls are called.  Those should not be used as
their exact meaning is sometimes unknown and they in parts duplicate
functionality present in the framebuffer interface.

There is no known user of these ioctls.

Subject: viafb: split global index up

This is the first step to remove an artificial global index that was used
in two ways:

1. As a pseudo index in the mode table.  Pseudo as you had to search
   through the table to find the referenced entry.  This was replaced by
   using a pointer to the entry.

2. As a shortcut to compare a combination of horizontal and vertical
   resolution at the same time.

   This was replaced by a "(hres<<16) | vres" which is good enough for
   now and the near future.  If vres or hres become greater than 2^16 this
   might indeed cause problems but this solution allows to split this
   indexing mess up without the requirement to do even more code changes.

This is a big change that will allow more clean ups.  It should be a bit
faster but that is probably not relevant for normal operation.  No
regressions expected but as this is a relatively big step heavy testing is
appreciated.

From 9b24b00c364bb3bfa717ba2ead258a527b20cc5f Mon Sep 17 00:00:00 2001
From: Florian Tobias Schandinat <FlorianSchandinat@gmx.de>
Date: Wed, 10 Mar 2010 15:21:29 -0800
Subject: viafb: remove the remaining VIA_RES_* uses

Remove the rest of the VIA_RES_* use cases.  Obviously this was no longer
useful.  Keep the related infrastructure/functions for later use.

No runtime impact expected.

From c5f06f5cddd6681b978ffdb53755e28eefccb1bb Mon Sep 17 00:00:00 2001
From: Florian Tobias Schandinat <FlorianSchandinat@gmx.de>
Date: Wed, 10 Mar 2010 15:21:30 -0800
Subject: viafb: some dvi cleanup

Remove some unused variables, move some dvi code around and store the
detected maximum resolution for later use.  The vertical resolution is
handled as the old code did it but I hope it can be read from the hardware
some day.

No runtime change expected.

Subject: viafb: reorder initialization for dual framebuffer mode

This patch reorders the initialization for dual framebuffer mode to not
ignore the settings for the first mode.  Previously they were overwritten
with the settings for the second one before they were applied.

This should have no effect on non dual framebuffer mode and do what the
user intended (initalization to desired modes) in dual framebuffer mode.

Subject: viafb: video address setting revisited

Set always the correct video address.  Especially do panning right on
multiple IGAs.

This should have no effect on single monitor mode (no SAMM, no dual fb).
For SAMM without dual fb this might break something as I really cannot
image what we are supposed to do for different resolutions with a single
framebuffer as we can't get data out of nowhere (no, they are not set up
in something one would call "expanded").  Previously I got for that funny
colored pictures as the second IGA pointed to video memory that was never
written to.  After the patch it'll work as cloning if the first and second
mode are identical (this was working already without SAMM).  Finally for
dual fb this should push us a step in the right direction.

Subject: viafb: make viafb_set_par more dual framebuffer compatible

This patch is an attempt to make viafb_set_par work correctly with more
than one framebuffer.  As modesetting is not (yet/easily) possible for
each individual IGA it uses the (normally to be avoided) global variables
viafbinfo{,1} to ensure that each function is called with the correct
values.

This patch (finally) allows usable dual framebuffer setups and should not
affect non dual fb ones.  It works in some (most?) configurations as
sometimes the driver still gets device connections wrong.  It can be worth
to try the devices in reverse order (in viafb_active_dev).

The user experience is still not very nice as:

- on the second fb you'll normally have a garbled picture as long as
  no application draws to it
  goal: auto on/off devices depending on reference counting
- as the whole machinery is always done you can see mode changes also
  in an unaffected framebuffer
  goal: split modesetting up for each individual IGA

Subject: viafb: introduce strict parameter checking

Refuse to work if wrong parameters are given.  This should improve the
user experience as it will be clear that something is wrong and not
silently ignored.

Subject: viafb: split color mode setting up

This patch splits color mode setting up in seperate functions.  Some
hardware initialization that was previously mixed with it is moved to
viafb_setmode.  As are the calls to the newly created function.  This is
yet another little step towards controlling each IGA on its own.

As this patch really aims too mimic the old behaviour no regressions are
expected.  However I noticed that 8bpp (or 6bpp?) seems actually a bit
broken before and after the patch.

Subject: viafb: remove dead code due to IGA1_IGA2

Some code depended on IGA1_IGA2 which was never set (at least with the
symbolic name).  Remove this dead code although it might one day be useful
to get a hint on how some things might work.  However as this is dead it
is likely full of bugs and would prevent a clean structure (as it has some
very strange things).

Dead code -> no regressions, at least if VIA doesn't do anything very ugly.

Subject: viafb: rework color checking

Make color checking a bit more tolerant in what values it allows and more
fine grained to later support 15 and 30 bits formats.  It splits the
filling of the color information in var to a seperate function and sets
some color related values in var that where previously untouched.

This could be a bug fix but at least I don't know any applications that
was fooled by not correctly setting the fields in var.  At least no
regressions are expected.

Subject: viafb: rework color setting

This is a rewritten version of viafb_setcolreg.  The hardware register
writes were split up and moved to hw.c where they belong as this is really
low level stuff.  It was made dual fb aware.

Furthermore viafb_setcmap was removed as the problem with 8bpp originated
from a bug in writing multiple color registers at once.  The removal of
viafb_setcmap might introduce a small performance regression but its
certainly better to receive the correct result a bit slower than a garbled
picture fast.  It should give us a working 8bpp mode and is more
extensible than the old hardcoded code.  No other regressions are expected
but as the hardware might be a bit picky it might cause some regressions
in 8bpp mode on some hardware although I doubt that.

Subject: viafb: support color depth 15 and 30

Add support for the color depth 15 on IGA1 and 30 on IGA1 and IGA2.  To
allow the usage of those the driver now refuses color depth that are
totally off and otherwise the selection in viafb_check_var is used.
Therefore the first call to this for the first framebuffer was delayed a
bit.  It only enables the new formats if they are requested exactly
(viafb_bpp=15|30).

As this is a new feature, no regressions are expected.  The color depth 15
was successfully tested.  Didn't get anything usable for 30 but that might
be the programs fault.  I would like to get some feedback whether it works
as expected or not if somebody knows a program/configuration where it
should.

Subject: broadsheetfb: support storing waveform

This patch adds waveform storing capability to broadsheetfb. It uses the
firmware class to retrieve the waveform, and the request to initiate the
waveform storing is done via a driver sysfs entry, loadstore_waveform.

Broadsheet is a framebuffer device.  It is slightly different from a
typical framebuffer controller that drives a normal TFT-LCD display.  Most
E-Ink display panels require a waveform in order to function.  That is, in
order to drive the state of a pixel to black, gray, or white, a specific
waveform is utilized.  Basically, that waveform represents the specific
E-field wiggling needed to get the pixel to its optimal state given
current temperature, and its previous state.  TN/IPS-LCDs use a similar
concept but the driving waveform is sufficiently simple that it is
internalized in the TFT source/gate driver.

These E-Ink waveforms are specific to a production batch.  That is, a
batch of display films are produced, then they get characterized and a
waveform is generated for that batch.  Broadsheet, typically, is attached
to its private SPI flash which is then flashed with this waveform.

Users won't be able to see the waveform and typically won't ever need to
know about it.  If however, the display panel attached to broadsheet is
changed out, then they will need to update their waveform.  That would
typically be done at a factory or repair facility rather than by a user.

Subject: fbdev: remove obsolete CONFIG_FB_SOFT_CURSOR

The config Option FB_SOFT_BUFFER was removed in
c465e05a03209651078b95686158648fd7ed84c5 ("fbcon/fbdev: Move softcursor
out of fbdev to fbcon").

While moving to fbcon this single driver has it left as a select in
KConfig / #ifdef in source.  This last occurence is removed here so the
option is really gone

There was some conditionalizing for the LWMON5 boards in kernel source.
However infrastructure for enabling this isn't here so probably the
special case code can go as well.

seek /dev/kmem: Device or resource busy
# kmem-seek 0xfffffffffffffff1
seek /dev/kmem: Block device required

- fix switch statement layout

- fix whitespace stuff

- fix comment layout

- remove unneeded inlining

- use __weak

- remove trailing whitespace

- move uncached_access() inside `#ifndef __HAVE_PHYS_MEM_ACCESS_PROT' - it
  is otherwise unused.

Remove unneeded initialization in tty_audit_fork().  It is called only via
copy_signal() and is useless after the kmem_cache_zalloc() was used.

Subject: ipmi: add parameter to limit CPU usage in kipmid

In some cases kipmid can use a lot of CPU.  This adds a way to tune the
CPU used by kipmid to help in those cases.  By setting kipmid_max_busy_us
to a value between 100 and 500, it is possible to bring down kipmid CPU
load to practically 0 without loosing too much ipmi throughput
performance.  Not setting the value, or setting the value to zero,
operation is unaffected.

Subject: edac: mpc85xx mask ecc syndrome correctly

With a 64-bit wide data bus only the lowest 8-bits of the ECC syndrome are
relevant.  With a 32-bit wide data bus only the lowest 16-bits are
relevant on most architectures.

Without this change, the ECC syndrome displayed can be mildly confusing,
eg:

  EDAC MPC85xx MC1: syndrome: 0x25252525

When in reality the ECC syndrome is 0x25.

A variety of Freescale manuals say a variety of different things about how
to decode the CAPTURE_ECC (syndrome) register.  I don't have a system with
a 32-bit bus to test on, but I believe the change is correct.  It'd be
good to get an ACK from someone at Freescale about this change though.

Subject: edac: mpc85xx improve SDRAM error reporting

Add the ability to detect the specific data line or ECC line which failed
when printing out SDRAM single-bit errors.  An example of a single-bit
SDRAM ECC error is below:

  EDAC MPC85xx MC1: Err Detect Register: 0x80000004
  EDAC MPC85xx MC1: Faulty data bit: 59
  EDAC MPC85xx MC1: Expected Data / ECC:  0x7f80d000_409effa0 / 0x6d
  EDAC MPC85xx MC1: Captured Data / ECC:  0x7780d000_409effa0 / 0x6d
  EDAC MPC85xx MC1: Err addr: 0x00031ca0
  EDAC MPC85xx MC1: PFN: 0x00000031

Knowning which specific data or ECC line caused an error can be useful in
tracking down hardware issues such as improperly terminated signals, loose
pins, etc.

Note that this feature is only currently enabled for 64-bit wide data
buses, 32-bit wide bus support should be added.

I don't have any 32-bit wide systems to test on.  If someone has one and
is willing to give this patch a shot with the check for a 64-bit data bus
removed it would be much appreciated and I can re-submit with both 32 and
64 bit buses supported.

Subject: edac: e752x: add dram scrubbing support

Add support to scrub DRAM using the e752x integrated memory scrubbing
engine.  The e7320/7520/e7525 chipsets support scrubbing at one rate while
the i3100 chipset supports a normal and fast rate.

A similar patch was originally sent back in 2008:
http://sourceforge.net/mailarchive/forum.php?thread_name=1204835866.25206.70.camel@localhost.localdomain&forum_name=bluesmoke-devel

This version has the following updates:
- Use 16-bit PCI config cycles to access MCHSCRB register
    e7320/7520/e7525 docs say register is 16bits wide, i3100 says 8.  I
    tested 16bits on the i3100 to be safe.
- Recalcuate and round actual scrub rates

The changes have been tested on an i3100-based board.

Subject: dma-mapping: pci: convert pci_set_dma_mask to call dma_set_mask

This changes pci_set_dma_mask to call the generic DMA API, dma_set_mask.

pci_set_dma_mask (in drivers/pci/pci.c) does the same things that
dma_set_mask does on all the architectures that use pci_set_dma_mask;
calls dma_supprted and sets dev->dma_mask.  So we safely change
pci_set_dma_mask to simply call dma_set_mask.

Subject: dma-mapping: dma-mapping.h: add dma_set_coherent_mask

dma_set_coherent_mask corresponds to pci_set_consistent_dma_mask.  This is
necessary to move to the generic device model DMA API from the PCI bus
specific API in the long term.

dma_set_coherent_mask works in the exact same way that
pci_set_consistent_dma_mask does.  So this patch also changes
pci_set_consistent_dma_mask to call dma_set_coherent_mask.

Subject: pps: LinuxPPS clients support

Each PPS source can be registered/deregistered into the system by using
special modules called "clients".  They simply define the PPS sources'
attributes and implement the time signal registration mechanism.

This patch adds a special directory for such clients and adds a dummy
client that can be useful to test system integrity on real systems.

Subject: drivers/char/mmtimer.c: eliminate useless code

The variable x is initialized twice to the same (side effect-free)
expression.  Drop one initialization.

A simplified version of the semantic match that finds this problem is:
(http://coccinelle.lip6.fr/)

// <smpl>
@forall@
idexpression *x;
identifier f!=ERR_PTR;
@@

x = f(...)
... when != x
(
x = f(...,<+...x...+>,...)
|
* x = f(...)
)
// </smpl>

Stefan observed:

  The next x = rb_entry(mn->next, struct mmtimer, list); is preceded by a
  test whether mn->next is NULL.

  Unless that test is redundant too, your patch fixes a potential NULL
  pointer dereference, introduced by commit cbacdd95 "SGI Altix mmtimer:
  allow larger number of timers per node" in 2.6.26.

Subject: mxcmmc: fixed max_seg_size value on initialization

This unpleasant typo appeared while porting the driver from Freescale
original sources, where anyone can easily find the correct version.

Current incorrect version potentially can influence segment and merge
handling in block subsystem via MMC request queue settings.

Subject: x86, k8 nb: Fix boot crash: enable k8_northbridges unconditionally on
 AMD systems

de957628ce7c84764ff41331111036b3ae5bad0f changed setting of the
x86_init.iommu.iommu_init function ptr only when GART IOMMU is
found.

One side effect of it is that num_k8_northbridges
is not initialized anymore if not explicitly
called. This resulted in uninitialized pointers in
<arch/x86/kernel/cpu/intel_cacheinfo.c:amd_calc_l3_indices()>,
for example, which uses the num_k8_northbridges thing through
node_to_k8_nb_misc().

Fix that through an initcall that runs right after the PCI
subsystem and does all the scanning. Then, remove initialization
in gart_iommu_init() which is a rootfs_initcall and we're
running before that.

What is more, since num_k8_northbridges is being used in other
places beside GART IOMMU, include it whenever we add AMD CPU
support. The previous dependency chain in kconfig contained

K8_NB depends on AGP_AMD64|GART_IOMMU

which was clearly incorrect. The more natural way in terms of
hardware dependency should be

AGP_AMD64|GART_IOMMU depends on K8_NB depends on CPU_SUP_AMD &&
PCI. Make it so Number One!

Subject: Input: ALPS - fix stuck buttons on some touchpads

Enable button release event redirection to the device that got the
button press not only for touchpads with interleaved protocols, but
unconditionally for all Alps touchpads. This is required at least
for the touchpads in Dell Inspiron 8200 and Latitude d630.

Subject: ACPI video: Be more liberal in validating _BQC behaviour

Right now, if _BQC returns a value we don't understand we immediately
invalidate it. Change this behaviour so we only invalidate it if it
continues to give an invalid answer after we've already set a brightness.

Per ACPI spec, _ERG method should be executed before device driver
gets control for hotpluged device. Firmware might do some configuration
there. See http://bugzilla.kernel.org/show_bug.cgi?id=10805. In this
machine, _REG method of docked device will configure cardbus bridge.

Subject: ACPI: processor: mv processor_core.c processor_driver.c

The ACPI processor driver can be built as a module. But it has
pieces of code that should always be built statically into the
kernel.

The plan is for processor_core.c to contain the static bits while
processor_driver.c contains the module-like bits.

Since the bulk of the code in the current processor_core.c is
module-like, first step is to rename the file to processor_driver.c

Next step will re-create processor_core.c and cherry-pick out
the static bits.

From 4d5d4cd88c542ff56cf7feacd29cc907f2abbfbb Mon Sep 17 00:00:00 2001

Subject: ACPI: processor: mv processor_pdc.c processor_core.c

We've renamed the old processor_core.c to processor_driver.c, to
convey the idea that it can be built modular and has driver-like
bits.

Now let's re-create a processor_core.c for the bits needed
statically by the rest of the kernel. The contents of processor_pdc.c
are a good starting spot, so let's just rename that file and
complete our three card monte.

Subject: ACPI: processor: export acpi_get_cpuid()

Rename static get_cpu_id() to acpi_get_cpuid() and export it.

This change also gives us an opportunity to remove the
#ifndef CONFIG_SMP from processor_driver.c and into a header file
where it properly belongs.

Subject: ACPI: processor: move acpi_get_cpuid into processor_core.c

Enumerating processors (via MADT/_MAT) belongs in the processor core,
which is always built-in, rather than living in the processor driver
which may not be built.

Subject: ACPI: processor: add internal processor_physically_present()

Detect if a processor is physically present before evaluating _PDC.

We want this because some BIOS will provide a _PDC even for processors
that are not present. These bogus _PDC methods then attempt to load
non-existent tables, which causes problems.

Avoid those bogus landmines.

Subject: ACPI: processor: driver doesn't need to evaluate _PDC

Now that the early _PDC evaluation path knows how to correctly
evaluate _PDC on only physically present processors, there's no
need for the processor driver to evaluate it later when it loads.

To cover the hotplug case, push _PDC evaluation down into the
hotplug paths.
