gfs2 and gfs2meta share an ->init_fs_context function which allocates an
args structure stored in fc->fs_private. gfs2 registers a ->free
function to free this memory when the fs_context is cleaned up, but
there was not one registered for gfs2meta, causing a leak.
Register a ->free function for gfs2meta. The existing gfs2_fc_free
function does what we need.

This is a usual small bump in the middle, we've got a set of ASoC

The only change in the core stuff is about (somewhat minor) PCM
debugfs error handling. The major changes are rather for Intel

samsung, stm) and codec fixes.
As non-ASoC changes, a couple of new HD-audio chip fixes and a

build_restore_pagemask() will restore the value of register $1/$at when
its restore_scratch argument is non-zero, and aims to do so by filling a
branch delay slot. Commit 0b24cae4d5 ("MIPS: Add missing EHB in mtc0
-> mfc0 sequence.") added an EHB instruction (Execution Hazard Barrier)
prior to restoring $1 from a KScratch register, in order to resolve a
hazard that can result in stale values of the KScratch register being
observed. In particular, P-class CPUs from MIPS with out of order
execution pipelines such as the P5600 & P6600 are affected.
Unfortunately this EHB instruction was inserted in the branch delay slot
causing the MFC0 instruction which performs the restoration to no longer
execute along with the branch. The result is that the $1 register isn't
actually restored, ie. the TLB refill exception handler clobbers it -
which is exactly the problem the EHB is meant to avoid for the P-class
CPUs.
Similarly build_get_pgd_vmalloc() will restore the value of $1/$at when
its mode argument equals refill_scratch, and suffers from the same
problem.
Fix this by in both cases moving the EHB earlier in the emitted code.
There's no reason it needs to immediately precede the MFC0 - it simply
needs to be between the MTC0 & MFC0.
This bug only affects Cavium Octeon systems which use
build_fast_tlb_refill_handler().

The sequence number of the timeout req (req->sequence) indicate the
expected completion request. Because of each timeout req consume a
sequence number, so the sequence of each timeout req on the timeout
list shouldn't be the same. But now, we may get the same number (also
incorrect) if we insert a new entry before the last one, such as submit
such two timeout reqs on a new ring instance below.
req->sequence
req_1 (count = 2): 2
req_2 (count = 1): 2
Then, if we submit a nop req, req_2 will still timeout even the nop req
finished. This patch fix this problem by adjust the sequence number of
each reordered reqs when inserting a new entry.

The sequence number of reqs on the timeout_list before the timeout req
should be adjusted in io_timeout_fn(), because the current timeout req

IB resources are bounded to IB device and file descriptors, both entities
are unaware to PID namespaces and to task lifetime.
The difference in model caused to unpredictable behavior for the following
scenario:
1. Create FD and context
2. Share it with ephemeral child
3. Create any object and exit that child
The end result of this flow, that those newly created objects will be
tracked by restrack, but won't be visible for users because task_struct
associated with them already exited.
The right thing is to rely on net namespace only for any filtering
purposes and drop PID namespace.

Two regression fixes for omap3 iommu. I missed applying two omap3
related iommu pdata quirks patches earlier because the kbuild test
robot produced errors on them for missing dependencies.
Fix ti-sysc interconnect target module driver handling for watchdog
quirk. I must have tested this earlier only with watchdog service
running, but clearly it does not do what it needs to do.

A recent commit removed the NULL pointer check from the clock_getres()
implementation causing a test case to fault.
POSIX requires an explicit NULL pointer check for clock_getres() aside of
the validity check of the clock_id argument for obscure reasons.
Add it back for both 32bit and 64bit.
Note, this is only a partial revert of the offending commit which does not
bring back the broken fallback invocation in the the 32bit compat
implementations of clock_getres() and clock_gettime().

When doing an out of tree build with O=, the nsdeps script constructs
the absolute pathname of the module source file so that it can insert
MODULE_IMPORT_NS statements in the right place. However, ${srctree}
contains an unescaped path to the source tree, which, when used in a sed
substitution, makes sed complain:
++ sed 's/[^ ]* *//home/jeyu/jeyu-linux\/&/g'
sed: -e expression #1, char 12: unknown option to `s'
The sed substitution command 's' ends prematurely with the forward
slashes in the pathname, and sed errors out when it encounters the 'h',
which is an invalid sed substitution option. To avoid escaping forward
slashes ${srctree}, we can use '|' as an alternative delimiter for
sed instead to avoid this error.

Update get_unlocked_entry() to check for NULL entries before checking
the entry order, otherwise NULL is misinterpreted as a present pte

an unlocked entry at the wrong order must fallback to lookup the correct
order.

The list_kref reaches a count of 0 when all the static OPPs are removed,
for example when dev_pm_opp_of_cpumask_remove_table() is called, though
the actual OPP table may not get freed as it may still be referenced by
other parts of the kernel, like from a call to
dev_pm_opp_set_supported_hw(). And if we call
dev_pm_opp_of_cpumask_add_table() again at this point, we must
reinitialize the list_kref otherwise the kernel will hit a WARN() in
kref infrastructure for incrementing a kref with value 0.
