"Here are some bugfixes for the drivers/staging tree for 3.8-rc4.
Nothing major, just a number of small fixes for problems that people
have reported, including finally tracking down the root of the 64/32
bit problem with the vt6656 that has been driving people crazy for a
while"

The sb105x driver calls parport_pc_probe_port() which isn't defined if
PARPORT_PC isn't enabled. Protecting it with CONFIG_PARPORT is not good
enough, must protect it with CONFIG_PARPORT_PC.

Commit 2e254212 broke listing of available network names, since it
clamped the length of the returned SSID to WLAN_BSSID_LEN (6) instead of
WLAN_SSID_MAXLEN (32).

Second round of fixes for IIO post 3.8-rc1
Two tiny fixes
* A build warning fix due to signed / unsigned comparison
* Missing sign extension in adis16080

| | |
| | |

| | |

The adis16080 reports sample values in twos complement. So we need to perform a
sign extension on the result, otherwise negative values will be reported
incorrectly as large positive values.

vt6656 has several headers that use the #pragma pack(1) directive to
enable structure packing, but never disable it. The layout of
structures defined in other headers can then depend on which order the
various headers are included in, breaking the One Definition Rule.
In practice this resulted in crashes on x86_64 until the order of header
inclusion was changed for some files in commit 11d404cb56ecd ('staging:
vt6656: fix headers and add cfg80211.'). But we need a proper fix that
won't be affected by future changes to the order of inclusion.
This removes the #pragma pack(1) directives and adds __packed to the
structure definitions for which packing appears to have been intended.

"Here are a number of small fixes to staging drivers for your 3.8-rc3

Well, the omapdrm fixes aren't really "small" but they were waiting on
a number of other drm patches to go in through the drm tree, and got

that people have been having with the driver.
Other than that one, it's a bunch of tiny bugfixes for a number of

Fixes a bug introduced by commit c8f2f0db1 ("zram: Fix handling
of incompressible pages") which caused invalid memory references
during disk write. Invalid references could occur in two cases:
- Incoming data expands on compression: In this case, reference was
made to kunmap()'ed bio page.
- Partial (non PAGE_SIZE) write with incompressible data: In this
case, reference was made to a kfree()'ed buffer.
Fixes bug 50081:

This solves runtime failures while trying to enable WDT3 related
functionality on firmware load, however it does affect other clocks
controlled by the driver. Seen on 3.8-rc1.
CCF provides clk_prepare and clk_unprepare for enable and disable
operations respectively, this needs to be called in the correct
order while handling clocks.
Code path to enable/disable dsp clocks can still be reached from an
atomic context, hence we can't use clk_prepare_enable and
clk_disable_unprepare yet.

Éric Piel reported a kernel oops in the "comedi_test" module. It was a
NULL pointer dereference within `waveform_ai_interrupt()` (actually a
timer function) that sometimes occurred when a running asynchronous
command is cancelled (either by the `COMEDI_CANCEL` ioctl or by closing
the device file).
This seems to be a race between the caller of `waveform_ai_cancel()`
which on return from that function goes and tears down the running
command, and the timer function which uses the command. In particular,
`async->cmd.chanlist` gets freed (and the pointer set to NULL) by
`do_become_nonbusy()` in "comedi_fops.c" but a previously scheduled
`waveform_ai_interrupt()` timer function will dereference that pointer
regardless, leading to the oops.
Fix it by replacing the `del_timer()` call in `waveform_ai_cancel()`
with `del_timer_sync()`.

The 'ni_at_a2150' module links to `cfc_write_to_buffer` in the
'comedi_fc' module, so selecting 'COMEDI_NI_AT_A2150' in the kernel config
needs to also select 'COMEDI_FC'.

When a low-level comedi driver auto-configures a device, a `struct
comedi_dev_file_info` is allocated (as well as a `struct
comedi_device`) by `comedi_alloc_board_minor()`. A pointer to the
hardware `struct device` is stored as a cookie in the `struct
comedi_dev_file_info`. When the low-level comedi driver
auto-unconfigures the device, `comedi_auto_unconfig()` uses the cookie
to find the `struct comedi_dev_file_info` so it can detach the comedi
device from the driver, clean it up and free it.
A problem arises if the user manually unconfigures and reconfigures the
comedi device using the `COMEDI_DEVCONFIG` ioctl so that is no longer
associated with the original hardware device. The problem is that the
cookie is not cleared, so that a call to `comedi_auto_unconfig()` from
the low-level driver will still find it, detach it, clean it up and free
it.
Stop this problem occurring by always clearing the `hardware_device`
cookie in the `struct comedi_dev_file_info` whenever the
`COMEDI_DEVCONFIG` ioctl call is successful.

The minimum period was set to 357 ns, while the divider for these boards is 50
ns. This prevented to output at maximum speed as ni_ao_cmdtest() would return
357 but would not accept it.
Not sure why it was set to 357 ns (this was done before the git history,
which starts 5 years ago). My guess is that it comes from reading the
specification stating a 2.8 MHz rate (~ 357 ns). The latest
specification states a 2.86 MHz rate (~ 350 ns), which makes a lot
more sense.
Tested on a pci-6251.

This patch changes the omapdrm KMS to bypass the omapdss "compat"
layer and use the core omapdss API directly. This solves some layering
issues that would cause unpin confusion vs GO bit status, because we
would not know whether a particular pageflip or overlay update has hit
the screen or not. Now instead we explicitly manage the GO bits in
dispc and handle the vblank/framedone interrupts ourself so that we
always know which buffers are being scanned out at any given time, and
so on.
As an added bonus, we no longer leave the last overlay buffer pinned
when the display is disabled, and have been able to add the previously
missing vblank event handling.

First round of fixes for IIO post 3.8-rc1.
A set of worthy if rather dull little fixes.
* A whole set of incorrect error handling on regulator voltage requests.
* An error in the probe path for max1363.
* A couple of Kconfig issues with missing/ignored dependencies.
* A nasty shift vs compare typo in adf4350
* Bug fixes for a silly error that prevents at91_adc driver building.

The commit c8442118 introduced a struct wireless_dev pointer
as a second argument of the function pointers set_tx_power
and get_tx_power. This patch adds the missing arguments for
the wlan-ng driver.

Some of the drivers that the sb105x SystemBase handles are for parallel
port cards. If PARPORT isn't configured, the build fails. Only
initialize the parallel port cards if PARPORT is configured in.

The sb105x SystemBase PCI UART driver in staging has code specific for
x86. This breaks allyesconfig builds for other archs. For now, the quick
fix is simply to make this driver depend on x86.
When I get time, I'll swap this card out of my main machine and put it
into my PowerPC64 box, and get it working there. Then it may become a
good samaritan and play nice with other archs.

Increasing ref counts of both dma-buf and gem for imported dma-buf come from gem
makes memory leak. release function of dma-buf cannot be called because f_count
of dma-buf increased by importing gem and gem ref count cannot be decrease
because of exported dma-buf.
So I add dma_buf_put() for imported gem come from its own gem into each drivers
having prime_import and prime_export capabilities. With this, only gem ref
count is increased if importing gem exported from gem of same driver.

git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
Pull user namespace changes from Eric Biederman:
"While small this set of changes is very significant with respect to
containers in general and user namespaces in particular. The user
space interface is now complete.
This set of changes adds support for unprivileged users to create user
namespaces and as a user namespace root to create other namespaces.
The tyranny of supporting suid root preventing unprivileged users from
using cool new kernel features is broken.
This set of changes completes the work on setns, adding support for
the pid, user, mount namespaces.
This set of changes includes a bunch of basic pid namespace
cleanups/simplifications. Of particular significance is the rework of
the pid namespace cleanup so it no longer requires sending out
tendrils into all kinds of unexpected cleanup paths for operation. At
least one case of broken error handling is fixed by this cleanup.
The files under /proc/<pid>/ns/ have been converted from regular files
to magic symlinks which prevents incorrect caching by the VFS,
ensuring the files always refer to the namespace the process is
currently using and ensuring that the ptrace_mayaccess permission
checks are always applied.
The files under /proc/<pid>/ns/ have been given stable inode numbers
so it is now possible to see if different processes share the same
namespaces.
Through the David Miller's net tree are changes to relax many of the
permission checks in the networking stack to allowing the user
namespace root to usefully use the networking stack. Similar changes
for the mount namespace and the pid namespace are coming through my
tree.
Two small changes to add user namespace support were commited here adn
in David Miller's -net tree so that I could complete the work on the
/proc/<pid>/ns/ files in this tree.
Work remains to make it safe to build user namespaces and 9p, afs,
ceph, cifs, coda, gfs2, ncpfs, nfs, nfsd, ocfs2, and xfs so the
Kconfig guard remains in place preventing that user namespaces from
being built when any of those filesystems are enabled.
Future design work remains to allow root users outside of the initial
user namespace to mount more than just /proc and /sys."
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: (38 commits)
proc: Usable inode numbers for the namespace file descriptors.
proc: Fix the namespace inode permission checks.

userns: Allow unprivilged mounts of proc and sysfs
userns: For /proc/self/{uid,gid}_map derive the lower userns from the struct file

The expressions tsk->nsproxy->pid_ns and task_active_pid_ns
aka ns_of_pid(task_pid(tsk)) should have the same number of
cache line misses with the practical difference that
ns_of_pid(task_pid(tsk)) is released later in a processes life.
Furthermore by using task_active_pid_ns it becomes trivial
to write an unshare implementation for the the pid namespace.
So I have used task_active_pid_ns everywhere I can.
In fork since the pid has not yet been attached to the
process I use ns_of_pid, to achieve the same effect.

omapdss_compat_init() and omapdss_compat_uninit() is called internally
by omapdss. This patch moves the calls to omapfb, omap_vout and omapdrm
drivers. omapdrm driver can later remove the call after non-compat
support has been implemented in omapdrm.

drivers/staging/media/lirc/lirc_serial.c: In function '__check_sense':
drivers/staging/media/lirc/lirc_serial.c:1301:1: warning: return from incompatible pointer type [enabled by default]
This can be trivially fixed by changing the 'sense' parameter from bool
to int. But, to be safe, we also need to make sure 'sense' will only be
-1, 0, or 1. There's no need to document the new values that are now
allowed for the 'sense' parameter, since they're basically useless.
