43d451f163 Merge branch 'mailbox-for-linus' of git://git.linaro.org/landing-teams/working/fujitsu/integration
Pull mailbox framework from Jassi Brar:
 "A framework for Mailbox controllers and clients have been cooking for
  more than a year now.

  Everybody in the CC list had been copied on patchset revisions and
  most of them have made sounds of approval, though just one concrete
  Reviewed-by.  The patchset has also been in linux-next for a couple of
  weeks now and no conflict has been reported.  The framework has the
  backing of at least 5 platforms, though I can't say if/when they
  upstream their drivers (some businesses have 'changed')"

(Further acked-by by Arnd Bergmann and Suman Anna in the pull request
thread)

 "Here's some more updates for powerpc for 3.18.

  They are a bit late I know, though must are actually bug fixes.  In my
  defence I nearly cut the top of my finger off last weekend in a

  waiting around for doctors.  True story, I can send photos if you like :)

  Probably the most interesting fix is the sys_call_table one, which
  enables syscall tracing for powerpc.  There's a fix for HMI handling
  for old firmware, more endian fixes for firmware interfaces, more EEH
  fixes, Anton fixed our routine that gets the current stack pointer,

c5ec618fbf watchdog: sunxi: Add A31 watchdog support
This patch adds support for the watchdog hardware found in A31 and
newer SoCs. This new hardware has registers at different offsets, and
the system reset control has been split out of the "mode" register
into a new "configuration" register.

Differences not supported by this driver include separate interrupt
lines for each watchdog, instead of sharing an interrupt line and
registers with the timer block.

f2147de334 watchdog: sunxi: support parameterized compatible strings
This patch adds support for hardware parameters tied to compatible
strings, so similar hardware can reuse the driver.

This will be used to support the newer watchdog found in A31 and
later SoCs. Differences in the new hardware include separate
interrupt lines for each watchdog, and corresponding interrupt
control/status registers. Watchdog control registers were also
slightly rearranged.

Also replace ioread32()/iowrite32() with readl()/writel() in various
places changed.

05e487d905 watchdog: qcom: register a restart notifier
The WDT's BITE_TIME warm-reset behavior can be leveraged as a last
resort mechanism for triggering chip reset.  Usually, other restart
methods (such as PS_HOLD) are preferrable for issuing a more complete
reset of the chip.  As such, keep the priority of the watchdog notifier
low.

fca8c0481b watchdog: xilinx: Remove .owner field for driver
There is no need to init .owner field.

Based on the patch from Peter Griffin <peter.griffin@linaro.org>
"mmc: remove .owner field for drivers using module_platform_driver"

This patch removes the superflous .owner field for drivers which
use the module_platform_driver API, as this is overriden in
platform_driver_register anyway."

Pull audit updates from Eric Paris:
 "So this change across a whole bunch of arches really solves one basic
  problem.  We want to audit when seccomp is killing a process.  seccomp
  hooks in before the audit syscall entry code.  audit_syscall_entry
  took as an argument the arch of the given syscall.  Since the arch is
  part of what makes a syscall number meaningful it's an important part
  of the record, but it isn't available when seccomp shoots the
  syscall...

  For most arch's we have a better way to get the arch (syscall_get_arch)
  So the solution was two fold: Implement syscall_get_arch() everywhere
  there is audit which didn't have it.  Use syscall_get_arch() in the
  seccomp audit code.  Having syscall_get_arch() everywhere meant it was
  a useless flag on the stack and we could get rid of it for the typical
  syscall entry.

  The other changes inside the audit system aren't grand, fixed some
  records that had invalid spaces.  Better locking around the task comm
  field.  Removing some dead functions and structs.  Make some things
  static.  Really minor stuff"

Pull more perf updates from Ingo Molnar:
 "A second (and last) round of late coming fixes and changes, almost all
  of them in perf tooling:

  User visible tooling changes:

   - Add period data column and make it default in 'perf script' (Jiri
     Olsa)

   - Add a visual cue for toggle zeroing of samples in 'perf top'
     (Taeung Song)

   - Improve callchains when using libunwind (Namhyung Kim)

  Tooling fixes and infrastructure changes:

   - Fix for double free in 'perf stat' when using some specific invalid
     command line combo (Yasser Shalabi)

   - Fix off-by-one bugs in map->end handling (Stephane Eranian)

   - Fix off-by-one bug in maps__find(), also related to map->end
     handling (Namhyung Kim)

   - Make struct symbol->end be the first addr after the symbol range,
     to make it match the convention used for struct map->end.  (Arnaldo
     Carvalho de Melo)

   - Fix perf_evlist__add_pollfd() error handling in 'perf kvm stat
     live' (Jiri Olsa)

   - Fix python test build by moving callchain_param to an object linked
     into the python binding (Jiri Olsa)

   - Document sysfs events/ interfaces (Cody P Schafer)

   - Fix typos in perf/Documentation (Masanari Iida)

   - Add missing 'struct option' forward declaration (Arnaldo Carvalho
     de Melo)

   - Add option to copy events when queuing for sorting across cpu
     buffers and enable it for 'perf kvm stat live', to avoid having
     events left in the queue pointing to the ring buffer be rewritten
     in high volume sessions.  (Alexander Yarygin, improving work done
     by David Ahern):

   - Do not include a struct hists per perf_evsel, untangling the
     histogram code from perf_evsel, to pave the way for exporting a
     minimalistic tools/lib/api/perf/ library usable by tools/perf and
     initially by the rasd daemon being developed by Borislav Petkov,
     Robert Richter and Jean Pihet.  (Arnaldo Carvalho de Melo)

   - Make perf_evlist__open(evlist, NULL, NULL), i.e. without cpu and
     thread maps mean syswide monitoring, reducing the boilerplate for
     tools that only want system wide mode.  (Arnaldo Carvalho de Melo)

   - Move exit stuff from perf_evsel__delete to perf_evsel__exit, delete
     should be just a front end for exit + free (Arnaldo Carvalho de
     Melo)

   - Add support to new style format of kernel PMU event.  (Kan Liang)

  and other misc fixes"

 "Here we have two bug fixes:

  1) The current thread's fault_code is not setup properly upon entry to
     do_sparc64_fault() in some paths, leading to spurious SIGBUS.

  2) Don't use a zero length array at the end of thread_info on sparc64,

Pull networking fixes from David Miller:
 "A quick batch of bug fixes:

  1) Fix build with IPV6 disabled, from Eric Dumazet.

  2) Several more cases of caching SKB data pointers across calls to
     pskb_may_pull(), thus referencing potentially free'd memory.  From
     Li RongQing.

  3) DSA phy code tests operation presence improperly, instead of going:

        if (x->ops->foo)
                r = x->ops->foo(args);

     it was going:

228b16cb13 Net: DSA: Fix checking for get_phy_flags function
The check for the presence or not of the optional switch function
get_phy_flags() called the function, rather than checked to see if it
is a NULL pointer. This causes a derefernce of a NULL pointer on all
switch chips except the sf2, the only switch to implement this call.

e2653143d7 sparc64: Do not define thread fpregs save area as zero-length array.
This breaks the stack end corruption detection facility.

What that facility does it write a magic value to "end_of_stack()"
and checking to see if it gets overwritten.

"end_of_stack()" is "task_thread_info(p) + 1", which for sparc64 is
the beginning of the FPU register save area.

So once the user uses the FPU, the magic value is overwritten and the
debug checks trigger.

Fix this by making the size explicit.

Due to the size we use for the fpsaved[], gsr[], and xfsr[] arrays we
are limited to 7 levels of FPU state saves.  So each FPU register set
is 256 bytes, allocate 256 * 7 for the fpregs area.
