In kobj_ns_current_may_mount the default should be to allow the mount.
The test is only for a single kobj_ns_type at a time, and unless there
is a reason to prevent it the mounting sysfs should be allowed.
Subsystems that are not registered can't have are not involved so can't
have a reason to prevent mounting sysfs.
This is a bug-fix to commit 7dc5dbc879bd ("sysfs: Restrict mounting
sysfs") that came in via the userns tree during the 3.12 merge window.

The 64-bit cmpxchg operation on the lockref is ordered by virtue of
hazarding between the cmpxchg operation and the reference count
manipulation. On weakly ordered memory architectures (such as ARM), it
can be of great benefit to omit the barrier instructions where they are
not needed.
This patch moves the lockless lockref code over to a cmpxchg64_relaxed
operation, which doesn't provide barrier semantics. If the operation
isn't defined, we simply #define it as the usual 64-bit cmpxchg macro.

is set
According to Designware I2C spec, if I2C_DYNAMIC_TAR_UPDATE is set to 1,
the 10-bit addressing mode is controlled by IC_10BITADDR_MASTER bit of
IC_TAR register instead of IC_CON register. The IC_10BITADDR_MASTER
in IC_CON register becomes read-only copy. Since I2C_DYNAMIC_TAR_UPDATE
value can't be detected from hardware register, so we will always set the
IC_10BITADDR_MASTER bit in both IC_CON and IC_TAR register whenever 10-bit
addresing mode is requested by user application.

ad65782fba50 (context_tracking: Optimize main APIs off case
with static key) converted context tracking main APIs to inline
function and left ARM asm callers behind.
This can be easily fixed by making ARM calling the post static
keys context tracking function. We just need to replicate the
static key checks there. We'll remove these later when ARM will
support the context tracking static keys.

On AMD family 14h, applying microcode patch on the a core (core0)
would also affect the other core (core1) in the same compute
unit. The driver would skip applying the patch on core1, but it
still need to update kernel structures to reflect the proper
patch level.
The current logic is not updating the struct
ucode_cpu_info.cpu_sig.rev of the skipped core. This causes the
/sys/devices/system/cpu/cpu1/microcode/version to report
incorrect patch level as shown below:
$ grep . cpu?/microcode/version

Commit f5ea1100 cleans up the disk to host conversions for
node directory entries, but because a variable is reused in
xfs_node_toosmall() the next node is not correctly found.
If the original node is small enough (<= 3/8 of the node size),
this change may incorrectly cause a node collapse when it should
not. That will cause an assert in xfstest generic/319:
Assertion failed: first <= last && last < BBTOB(bp->b_length),
file: /root/newest/xfs/fs/xfs/xfs_trans_buf.c, line: 569
Keep the original node header to get the correct forward node.
(When a node is considered for a merge with a sibling, it overwrites the
sibling pointers of the original incore nodehdr with the sibling's
pointers. This leads to loop considering the original node as a merge
candidate with itself in the second pass, and so it incorrectly
determines a merge should occur.)

BIOS can mark a pin as "no physical connection" if the port is used by an
integrated display which is not audio capable. And audio driver will overlook
such pins.
On Haswell, such a disconneted pin will keep muted and connected to the 1st
converter by default. But if the 1st convertor is assigned to a connected pin
for audio streaming. The muted disconnected pin can make the connected pin
no sound output.
So this patch avoids using assigned converters for all unused pins for Haswell,
including the disconected pins.

Some variants of Exynos MCT, namely exynos4210-mct at the moment, use
normal, shared interrupts for local timers. This means that each
interrupt must have correct affinity set to fire only on CPU
corresponding to given local timer.
However after recent conversion of clocksource drivers to not use the
local timer API for local timer initialization any more, the point of
time when local timers get initialized changed and irq_set_affinity()
fails because the CPU is not marked as online yet.
This patch fixes this by moving the call to irq_set_affinity() to
CPU_ONLINE notification, so the affinity is being set when the CPU goes
online.
This fixes a regression introduced by commit
ee98d27df6 ARM: EXYNOS4: Divorce mct from local timer API
which rendered all Exynos4210 based boards unbootable due to
failing irq_set_affinity() making local timers inoperatible.

i915: bail out earlier when shrinker cannot acquire mutex
SHRINK_STOP was added to tell the core shrinker code to bail out and
go to the next shrinker since the i915 shrinker couldn't acquire
required locks. But the SHRINK_STOP return code was added to the
->count_objects callback and not the ->scan_objects callback as it
should have been, resulting in tons of dmesg noise like
shrink_slab: i915_gem_inactive_scan+0x0/0x9c negative objects to delete nr=-xxxxxxxxx
Fix discusssed with Dave Chinner.

git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm
Pull device-mapper fixes from Mike Snitzer:
"A few fixes for dm-snapshot, a 32 bit fix for dm-stats, a couple error
handling fixes for dm-multipath. A fix for the thin provisioning
target to not expose non-zero discard limits if discards are disabled.
Lastly, add two DM module parameters which allow users to tune the
emergency memory reserves that DM mainatins per device -- this helps
fix a long-standing issue for dm-multipath. The conservative default
reserve for request-based dm-multipath devices (256) has proven
problematic for users with many multipathed SCSI devices but
relatively little memory. To responsibly select a smaller value users
should use the new nr_bios tracepoint info (via commit 75afb352
"block: Add nr_bios to block_rq_remap tracepoint") to determine the
peak number of bios their workloads create"

git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc
Pull powerpc fixes from Ben Herrenschmidt:
"Here are a few things for -rc2, this time it's all written by me so it
can only be perfect .... right ? :)
So we have the fix to call irq_enter/exit on the irq stack we've been
discussing, plus a cleanup on top to remove an unused (and broken)
stack limit tracking feature (well, make it 32-bit only in fact where
it is used and works properly).
Then we have two things that I wrote over the last couple of days and
made the executive decision to include just because I can (and I'm
sure you won't object .... right ?).
They fix a couple of annoying and long standing "issues":
- We had separate zImages for when booting via Open Firmware vs.
booting via a flat device-tree, while it's trivial to make one that
deals with both
- We wasted a ton of cycles spinning secondary CPUs uselessly at boot
instead of starting them when needed on pseries, thus contributing
significantly to global warming"

git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent
Pull perf/urgent fixes from Arnaldo Carvalho de Melo:
* It was possible to use an uninitialized buffer when reading
kernel modules information and checking if the file was a
/proc/sys/kernel/kptr_restrict'ed one, fix for this from
Adrian Hunter.
* The libbfd demangler doesn't handle cloned functions (e.g. symbol.clone.NUM),
feed it unsuffixed symbol names, workaround from Andi Kleen.
* Fix segfault in 'perf trace' when processing perf.data files with PERF_RECORD_MMAP2
records, recently added but not handled in this tool, from David Ahern.
* Fix libdl related build in old systems like Fedora 12, from David Ahern.
* Make 'perf kmem' work again on non NUMA machines, fix from Jiri Olsa.
* Fix probing symbols with optimization suffix in 'perf probe' where some
operations that are entirely user level and involves vmlinux/DWARF were working
but when the symbol name was fed to the kprobes tracer, the in kernel code
would use /proc/kallsyms where the name had the suffix, from Masami Hiramatsu.
