Fixed another condition of virtqueue_kick() not holding the lock.

If disk stats are enabled on the queue, a request needs to
be marked with REQ_IO_STAT for accounting to be active on
that request. This fixes an issue with virtio-blk not
showing up in /proc/diskstats after the conversion to
blk-mq.
Add QUEUE_FLAG_MQ_DEFAULT, setting stats and same cpu-group
completion on by default.

The data type of max_sectors and max_hw_sectors in queue settings are
unsigned int. But these values are passed to __bio_add_page() as an
argument whose data type is unsigned short. In the worst case such as
max_sectors is 0x10000, bio_add_page() can't add a page and IOs can't
proceed.

This reverts commit 69f0554ec2.
This patch breaks randconfig on at least the x86-64 architecture, and
most likely on others. There is work underway to support uncompressed
kernels in a generic way, but it looks like it will amount to
rewriting the support from scratch; see the LKML thread in the Link:
for info.
Therefore, revert this change and wait for the fix.

Pull CIFS fixes from Steve French:
"A set of cifs fixes most important of which is Pavel's fix for some
problems with handling Windows reparse points and also the security
fix for setfacl over a cifs mount to Samba removing part of the ACL.
Both of these fixes are for stable as well.
Also added most of copychunk (copy offload) support to cifs although I
expect a final patch in that series (to fix handling of larger files)
in a few days (had to hold off on that in order to incorporate some
additional code review feedback).
Also added support for O_DIRECT on forcedirectio mounts (needed in
order to run some of the server benchmarks over cifs and smb2/smb3
mounts)"

the following areas: performance, avoiding waste of entropy, better
tracking of entropy estimates, support for non-x86 platforms that have
a register which can't be used for fine-grained timekeeping, but which
might be good enough for the random driver.
Also add some printk's so that we can see how quickly /dev/urandom can
get initialized, and when programs try to use /dev/urandom before it
is fully initialized (since this could be a security issue). This
shouldn't be an issue on x86 desktop/laptops --- a test on my Lenovo
T430s laptop shows that /dev/urandom is getting fully initialized
approximately two seconds before the root file system is mounted
read/write --- this may be an issue with ARM and MIPS embedded/mobile
systems, though. These printk's will be a useful canary before
potentially adding a future change to start blocking processes which
try to read from /dev/urandom before it is initialized, which is
something FreeBSD does already for security reasons, and which
security folks have been agitating for Linux to also adopt.

Also add some printk's so that we can see how quickly /dev/urandom can
get initialized, and when programs try to use /dev/urandom before it
is fully initialized (since this could be a security issue). This
shouldn't be an issue on x86 desktop/laptops --- a test on my Lenovo
T430s laptop shows that /dev/urandom is getting fully initialized
approximately two seconds before the root file system is mounted
read/write --- this may be an issue with ARM and MIPS embedded/mobile
systems, though. These printk's will be a useful canary before
potentially adding a future change to start blocking processes which
try to read from /dev/urandom before it is initialized, which is
something FreeBSD does already for security reasons, and which
security folks have been agitating for Linux to also adopt"

ASoC: Fixes for v3.13
A few fixes in drivers, the i.MX and wm8962 fixes are for a pretty nasty
issues for users of those drivers if they run into them.
Commit 7d02c4d64d ("iommu/shmobile: Enable the driver on all ARM
platforms") completely brokenly enabled the shmobile-iommu driver under
COMPILE_TEST.
It's bogus, because it won't compile anywhere else than ARM, since it
tries to include <asm/dma-iommu.h>, which is very much ARM-only.
So remove the bogus COMPILE_TEST dependency, which just causes
allmodconfig to fail on non-ARM platforms.

Merge tag 'at91-fixes-non-critical' of git://github.com/at91linux/linux-at91 into fixes
From Nicolas Ferre, fixes for early boot hangs on at91:
Fixes for RTT & RTC interrupts that can fire early during boot process
and kill the system.

Defaulting to m seem to prevent building the pnfs layout modules into the
kernel. Default to the value of CONFIG_NFS_V4 make sure they are
built in for built-in NFSv4 support and modular for a modular NFSv4.

The current test on valid use of the "migration" mount option can never
report an error as it will only do so if
mnt->version !=4 && mnt->minor_version != 0
(and some other condition), but if that test would succeed, then the previous
test has already gone-to out_minorversion_mismatch.
So change the && to an || to get correct semantics.

OMAP device hooks around suspend|resume_noirq ensures that hwmod
devices are forced to idle using omap_device_idle/enable as part of
the last stage of suspend activity.
For a device such as i2c who uses autosuspend, it is possible to enter
the suspend path with dev->power.runtime_status = RPM_ACTIVE.
As part of the suspend flow, the generic runtime logic would increment
it's dev->power.disable_depth to 1. This should prevent further
pm_runtime_get_sync from succeeding once the runtime_status has been
set to RPM_SUSPENDED.
Now, as part of the suspend_noirq handler in omap_device, we force the
following: if the device status is !suspended, we force the device
to idle using omap_device_idle (clocks are cut etc..). This ensures
that from a hardware perspective, the device is "suspended". However,
runtime_status is left to be active.
*if* an operation is attempted after this point to
pm_runtime_get_sync, runtime framework depends on runtime_status to
indicate accurately the device status, and since it sees it to be
ACTIVE, it assumes the module is functional and returns a non-error
value. As a result the user will see pm_runtime_get succeed, however a
register access will crash due to the lack of clocks.
To prevent this from happening, we should ensure that runtime_status
exactly indicates the device status. As a result of this change
any further calls to pm_runtime_get* would return -EACCES (since
disable_depth is 1). On resume, we restore the clocks and runtime
status exactly as we suspended with. These operations are not expected
to fail as we update the states after the core runtime framework has
suspended itself and restore before the core runtime framework has
resumed.

Heiko Carstens noticed that btrfs was using empty_zero_page
incorrectly. He explained:
The definition of empty_zero_page is architecture specific. It
is (currently) either a character array, an unsigned long
containing the address of the empty_zero_page, or even worse
only the address of the struct page belonging to the
empty_zero_page.
This commit changes btrfs to use a for-loop instead. On x86
the resulting .ko is smaller, and we're no longer worrying about
how each arch builds its zeros.

Make sure the RTT-interrupts are masked at boot by adding a new helper
function to be used at SOC-init.
This fixes hanged boot on all AT91 SOCs with an RTT, for example, if an
RTT-alarm goes off after a non-clean shutdown (e.g. when using RTC
wakeup).
The RTC and RTT-peripherals are powered by backup power (VDDBU) (on all
AT91 SOCs but RM9200) and are not reset on wake-up, user, watchdog or
software reset. This means that their interrupts may be enabled during
early boot if, for example, they where not disabled during a previous
shutdown (e.g. due to a buggy driver or a non-clean shutdown such as a
user reset). Furthermore, an RTC or RTT-alarm may also be active.
The RTC and RTT-interrupts use the shared system-interrupt line, which
is also used by the PIT, and if an interrupt occurs before a handler
(e.g. RTC-driver) has been installed this leads to the system interrupt
being disabled and prevents the system from booting.
Note that when boot hangs due to an early RTC or RTT-interrupt, the only
way to get the system to start again is to remove the backup power (e.g.
battery) or to disable the interrupt manually from the bootloader. In
particular, a user reset is not sufficient.

We moved minor deallocation to drm_dev_free() in:
commit 8f6599da8e
Author: David Herrmann <dh.herrmann@gmail.com>
Date: Sun Oct 20 18:55:45 2013 +0200
drm: delay minor destruction to drm_dev_free()
However, this causes a call to drm_unplug_minor(), which should just do
nothing as drm_dev_unregister() already called this.
But a separate patch caused kdev lifetime changes:
commit 5bdebb183c
Author: Dave Airlie <airlied@redhat.com>
Date: Fri Oct 11 14:07:25 2013 +1000
drm/sysfs: sort out minor and connector device object lifetimes.
Thus making our dev_is_registered() call useles (and even segfault if it
is NULL). Replace it with a simple !kdev test and we're fine.
