Pull irq code updates from Thomas Gleixner:
 "The irq department proudly presents:

   - Another tree wide sweep of irq infrastructure abuse.  Clear winner
     of the trainwreck engineering contest was:
         #include "../../../kernel/irq/settings.h"

   - Tree wide update of irq_set_affinity() callbacks which miss a cpu
     online check when picking a single cpu out of the affinity mask.

   - Tree wide consolidation of interrupt statistics.

   - Updates to the threaded interrupt infrastructure to allow explicit
     wakeup of the interrupt thread and a variant of synchronize_irq()
     which synchronizes only the hard interrupt handler.  Both are
     needed to replace the homebrewn thread handling in the mmc/sdhci
     code.

   - New irq chip callbacks to allow proper support for GPIO based irqs.
     The GPIO based interrupts need to request/release GPIO resources
     from request/free_irq.

   - A few new ARM interrupt chips.  No revolutionary new hardware, just
     differently wreckaged variations of the scheme.

   - Small improvments, cleanups and updates all over the place"

I was hoping that that trainwreck engineering contest was a April Fools'
joke.  But no.

41b5368f31 ARM: kprobes-test: Workaround GAS .align bug
By default if no fill symbol is given to .align directive in a code
section it fills gap with NOPs. If previous fragment is not
instruction-aligned, additional pre-alignment is done by zero bytes
before NOPs. These zero bytes are marked as data by special symbol $d in
symbol table. Unfortunately GAS assumes that there is only code in the
code section so it "puts back" code symbol $a at the end of this
pre-alignment. So if there is some data after alignment it will be
interpreted as code and will be swapped back to LE for BE8 system during
a final linking.

If explicit fill value is given to .align, the NOP-padding code is
skipped and symbol table does not get messed-up.

So the workaround for this issue:
Use explicit fill value if data should be aligned in the code section.

     drivers are added on top of that and several are added to replace
     older drivers which were doing their own things (older ones are

5d50ffd7c3 locks: add new fcntl cmd values for handling file private locks
Due to some unfortunate history, POSIX locks have very strange and
unhelpful semantics. The thing that usually catches people by surprise
is that they are dropped whenever the process closes any file descriptor
associated with the inode.

This is extremely problematic for people developing file servers that
need to implement byte-range locks. Developers often need a "lock
management" facility to ensure that file descriptors are not closed
until all of the locks associated with the inode are finished.

Additionally, "classic" POSIX locks are owned by the process. Locks
taken between threads within the same process won't conflict with one
another, which renders them useless for synchronization between threads.

This patchset adds a new type of lock that attempts to address these
issues. These locks conflict with classic POSIX read/write locks, but
have semantics that are more like BSD locks with respect to inheritance
and behavior on close.

This is implemented primarily by changing how fl_owner field is set for
these locks. Instead of having them owned by the files_struct of the
process, they are instead owned by the filp on which they were acquired.
Thus, they are inherited across fork() and are only released when the
last reference to a filp is put.

These new semantics prevent them from being merged with classic POSIX
locks, even if they are acquired by the same process. These locks will
also conflict with classic POSIX locks even if they are acquired by
the same process or on the same file descriptor.

The new locks are managed using a new set of cmd values to the fcntl()
syscall. The initial implementation of this converts these values to
"classic" cmd values at a fairly high level, and the details are not
exposed to the underlying filesystem. We may eventually want to push
this handing out to the lower filesystem code but for now I don't
see any need for it.

Also, note that with this implementation the new cmd values are only
available via fcntl64() on 32-bit arches. There's little need to
add support for legacy apps on a new interface like this.

f8bbbfc3b9 net: filter: add jited flag to indicate jit compiled filters
This patch adds a jited flag into sk_filter struct in order to indicate
whether a filter is currently jited or not. The size of sk_filter is
not being expanded as the 32 bit 'len' member allows upper bits to be
reused since a filter can currently only grow as large as BPF_MAXINSNS.

Therefore, there's enough room also for other in future needed flags to
reuse 'len' field if necessary. The jited flag also allows for having
alternative interpreter functions running as currently, we can only
detect jit compiled filters by testing fp->bpf_func to not equal the
address of sk_run_filter().

Merge "Samsung PM related 2nd updates for v3.15" from Kukjin Kim:

From Tomasz Figa <t.figa@samsung.com>:
Current Samsung PM code is heavily unprepared for multiplatform
systems. The design implies accessing functions and global
variables defined in particular mach- subdirectory from common
code in plat-, which is not allowed when building ARCH_MULTIPLATFORM.
In addition there is a lot of forced code unification, which makes
common function handle any possible quirks of all supported SoCs.
In the end this design turned out to not work too well, ending with
a lot of empty functions exported from mach-, just because code in
common pm.c calls them. Moreover, recent trend of moving lower level
suspend/resume code to proper drivers, like pinctrl or clk, made a
lot of code there redundant, especially on DT-only platforms like
Exynos.

Merge "Samsung S2R PM updates for v3.15" from Kukjin Kim:

From Tomasz Figa:
This series reworks suspend/resume handling of Samsung clock drivers
to cover more SoC specific aspects that are beyond simple register
save and restore. The goal is to have all the suspend/resume code
that touches the clock controller in single place, which is the clock
driver.

027f3f9696 ARM: cache-tauros2: remove ARMv6 code
When building a kernel with support for both ARMv6 and ARMv7 but
no MMU, the call from tauros2_internal_init to adjust_cr causes
a link error. While that could probably be resolved, we don't
actually support cache-tauros2 on ARMv6 any more. All PJ4 CPU
implementations support both ARMv6 and ARMv7 and we already assume
that we are using them only in ARMv7 mode.

Removing the ARMv6 code path reduces the code size and avoids
the linker error.

f8afae40a0 ARM: moxart: fix CPU selection
Moxart uses an FA526 CPU core, which is ARMv4 based, not ARMv4T.
Before moxart, we had no CONFIG_MULTI_V4 option, since no ARMv4 platform
was enabled for multiplatform. This now adds the missing option, which
will give us slightly more efficient code on pure moxart kernels,
because we can build a pure FA526 kernel now rather than a combined
FA526+ARM920T kernel that we used to.
