The error message 'NMI watchdog failed to create perf event...'
does not make it clear that this is a fatal error for the
watchdog. It also currently prints the error value as a
pointer, rather than extracting the error code with PTR_ERR().
Fix that.
Add a note to the description of the 'nowatchdog' kernel
parameter to associate it with this message.

isr_ack is never initialized. So, until the first PIC reset, interrupts
may fail to be injected. This can cause Windows XP to fail to boot, as
reported in the fallout from the fix to
https://bugzilla.kernel.org/show_bug.cgi?id=21962.

We use the physical address instead of the base gfn for the four
PAE page directories we use in unpaged mode. When the guest accesses
an address above 1GB that is backed by a large host page, a BUG_ON()
in kvm_mmu_set_gfn() triggers.

The multi-component patch(commit f0fba2ad1) moved the allocation of the
register cache from the driver to the ASoC core. Most drivers where adjusted to
this, but the wm8753 driver still uses its own register cache for its
private functions, while functions from the ASoC core use the generic cache.
Furthermore the generic cache uses zero-based numbering while the wm8753 cache
uses one-based numbering.
Thus we end up with two from each other incoherent caches, which leads to undefined
behaviour and crashes.
This patch fixes the issue by changing the wm8753 driver to use the generic
register cache in its private functions.

The load_mixer_volumes() function, which can be triggered by
unprivileged users via the SOUND_MIXER_SETLEVELS ioctl, is vulnerable to
a buffer overflow. Because the provided "name" argument isn't
guaranteed to be NULL terminated at the expected 32 bytes, it's possible
to overflow past the end of the last element in the mixer_vols array.
Further exploitation can result in an arbitrary kernel write (via
subsequent calls to load_mixer_volumes()) leading to privilege
escalation, or arbitrary kernel reads via get_mixer_levels(). In
addition, the strcmp() may leak bytes beyond the mixer_vols array.

This lead to non-selected, non-user-selectable options to be written
out to .config. This is not only pointless, but also preventing the
user to be prompted should any of those options eventually become
visible (e.g. by de-selecting the *_AUTO options the "visible"
attribute was added for.
Furthermore it is quite logical for the "visible" attribute of a menu
to control the visibility of all contained prompts, which is what the
patch does.

The IPS driver is designed to be able to run detached from i915 and
just not enable GPU turbo in that case, in order to avoid module
dependencies between the two drivers. This means that we don't know
what the load order between the two is going to be, and we had
previously only supported IPS after (optionally) i915, but not i915
after IPS. If the wrong order was chosen, you'd get no GPU turbo, and
something like half the possible graphics performance.

This reverts commit 7e24cce38a99f373450db67bf576fe73e8168d66 because it
was never appropriate for mainline.
Do not check for init flag before starting I/O - zram module is unusable
without this fix.
The oops mentioned in the reverted commit message was actually a problem
only with the zram version as present in project's own repository where
we allocate struct zram_stats_cpu upon device initialization. OTOH, In
mainline/staging version of zram, we allocate struct stats upfront, so
this oops cannot happen in mainline version.
Checking for init_done flag in zram_make_request() results in a *no-op*
for any I/O operation since we simply always return success. This flag
is actually set when the first write occurs on a zram disk which
triggers its initialization.

When SPI wake up from OFF mode, CS is in the wrong state: force it to the
inactive state.
During the system life, I monitored the CS behavior using a oscilloscope.
I also activated debug in omap2_mcspi, so I saw when driver disable the clocks
and restore context when device is not used.Each time the CS was in the correct
state. It was only when system was put suspend to ram with off-mode activated
that on resume the CS was in wrong state( ie activated).
Changelog:
* Change from v1 to v2:
- Rebase on linus/master (after 2.6.37-rc1)
- Do some clean-up and fix indentation on both patches
- Add more explanations for patch 2
* Change from v2 to v3:
- Use directly resume function of spi_master instead of using function
- from spi_device as Grant Likely pointed it out.
- Force this transition explicitly for each CS used by a device.
* Change from v3 to v4:
- Patch clean-up according to Kevin Hilman and checkpatch.
- Now force CS to be in inactive state only if it was inactive when it was
suspended.
* Change from v4 to v5:
- Rebase on linus/master (after 2.6.37-rc3)
- Collapse some lines as pointed by Grant Likely
- Fix a spelling
* Change from v5 to v6:
- Rebase on linus/master (after 2.6.37-rc7)
- Use CONFIG_SUSPEND instead of CONFIG_PM
- Didn't use legacy PM methods anymore. Instead, add a struct dev_pm_ops and
add the resume method there.
- Fix multi-line comment style
* Change from v6 to v7:
- Rebase on linus/master (after 2.6.37-rc8)
- Drop an extra line

At __mem_cgroup_try_charge(), VM_BUG_ON(!mm->owner) is checked.
But as commented in mem_cgroup_from_task(), mm->owner can be NULL
in some racy case. This check of VM_BUG_ON() is bad.
A possible story to hit this is at swapoff()->try_to_unuse(). It passes
mm_struct to mem_cgroup_try_charge_swapin() while mm->owner is NULL. If we
can't get proper mem_cgroup from swap_cgroup information, mm->owner is used
as charge target and we see NULL.

When racing on adding into user cache, the new allocated from mm slab
is freed without putting user namespace.
Since the user namespace is already operated by getting, putting has
to be issued.

Fix two related problems in the event-copying loop of
ring_buffer_read_page.
The loop condition for copying events is off-by-one.
"len" is the remaining space in the caller-supplied page.
"size" is the size of the next event (or two events).
If len == size, then there is just enough space for the next event.
size was set to rb_event_ts_length, which may include the size of two
events if the first event is a time-extend, in order to assure time-
extends are kept together with the event after it. However,
rb_advance_reader always advances by one event. This would result in the
event after any time-extend being duplicated. Instead, get the size of
a single event for the memcpy, but use rb_event_ts_length for the loop
condition.

x86/microcode: Fix double vfree() and remove redundant pointer checks before vfree()

vfree()
In arch/x86/kernel/microcode_intel.c::generic_load_microcode()
we have this:
while (leftover) {
...
if (get_ucode_data(mc, ucode_ptr, mc_size) ||
microcode_sanity_check(mc) < 0) {
vfree(mc);
break;
}
...
}
if (mc)
vfree(mc);
This will cause a double free of 'mc'. This patch fixes that by
just removing the vfree() call in the loop since 'mc' will be
freed nicely just after we break out of the loop.
There's also a second change in the patch. I noticed a lot of
checks for pointers being NULL before passing them to vfree().
That's completely redundant since vfree() deals gracefully with
being passed a NULL pointer. Removing the redundant checks
yields a nice size decrease for the object file.

In the error-path where PM notifies PM_POST_RESTORE, the rescan-blockage
should be cleared as well. Otherwise it'll be never re-probed.
Also, as a bonus, this fixes a bug in S4 with user-mode suspend in the
current code, as it sends PM_POST_RESTORE instead of
PM_POST_HIBERNATION wrongly.

Based on report made by Yauhen in:
"MMC: Fix multiblock SDIO transfers in AT91 MCI" patch,
I report those changes to the brother driver: atmel-mci.
So, this patch sets SDIO transfer types: SDIO block and SDIO byte
transfers instead of using ordinary MMC block transfers.
It is checking opcode for SDIO CMD53 and setting transfer
type in MCI_CMDR register properly.

The AT91 MCI has special SDIO transfer types: SDIO block and SDIO byte
transfers, but at91_mci driver doesn't use them and handles all SDIO
transfers as ordinary MMC block transfers. This causes problems for
multiple-block SDIO transfers (in particular for 256-bytes blocks).
Fix this situation by checking the opcode for SDIO CMD53 and setting
the transfer type in the AT91_MCI_CMDR register properly.
This patch was tested with libertas SDIO driver: problem with TX
timeouts on big packets was eliminated.
