c2740a87ca perf thread: Rename perf_event__preprocess_sample_addr to thread__resolve
Since none of the perf_event fields are used anymore, just the
perf_sample ones, and since this resolves to (map, symbol) from data
structures within struct thread, rename it to thread__resolve and make
the argument ordering similar to the one in machine__resolve().

bb3eb56622 perf machine: Rename perf_event__preprocess_sample to machine__resolve
Since we only deal with fields in the passed struct perf_sample move
this method to struct machine, that is where the perf_sample fields
will be resolved to a struct addr_location, i.e. thread, map, symbol,
etc.

473398a21d perf tools: Add cpumode to struct perf_sample
To avoid parsing event->header.misc in many locations.

This will also allow setting perf.sample.{ip,cpumode} in a single place,
from tracepoint fields, as needed by 'perf kvm' with PPC guests, where
the guest hardware counters is not available at the host.

c95a23da2e parisc: Panic immediately when panic_on_oops
PA-RISC wants to sleep 5 seconds before panicking when panic_on_oops

may want their systems to fail as quickly as possible.

Users who want to delay reboot after panic can use PANIC_TIMEOUT.

33c1f638a0 The clk changes for this release cycle are mostly dominated by
new device support in terms of LoC, but there has been some cleanup
 in the core as well as the usual minor clk additions to various
 drivers.
 
 Core:
 
  - parent tracking has been simplified
 
  - CLK_IS_ROOT is now a no-op flag, cleaning up drivers has started
 
  - of_clk_init() doesn't consider disabled DT nodes anymore
 
  - clk_unregister() had an error path bug squashed
 
  - of_clk_get_parent_count() has been fixed to only return unsigned ints
 
  - HAVE_MACH_CLKDEV is removed now that the last arch user (ARM) is gone
 
 New Drivers:
 
  - NXP LPC18xx creg
 
  - QCOM IPQ4019 GCC
 
  - TI dm814x ADPLL
 
  - i.MX6QP
 
 Updates:
 
  - Cyngus audio clks found on Broadcom iProc devices
 
  - Non-critical fixes for BCM2385 PLLs
 
  - Samsung exynos5433 updates for clk id errors, HDMI support,
    suspend/resume simplifications
 
  - USB, CAN, LVDS, and FCP clks on shmobile devices
 
  - sunxi got support for more clks on new SoCs and went through a minor
    refactoring/rewrite to use a simpler factor clk construct
 
  - rockchip added some more clk ids and added suport for fraction dividers
 
  - QCOM GDSCs in msm8996
 
  - A new devm helper to make adding custom actions simpler (acked by Greg)

fbda4b38fa ACPI / PM: Runtime resume devices when waking from hibernate
Commit 58a1fbbb2e ("PM / PCI / ACPI: Kick devices that might have been
reset by firmware") added a runtime resume for devices that were runtime
suspended when the system entered suspend-to-RAM.

Briefly, the motivation was to ensure that devices did not remain in a
reset-power-on state after resume, potentially preventing deep SoC-wide
low-power states from being entered on idle.

Currently we're not doing the same when leaving suspend-to-disk and this
asymmetry is a problem if drivers rely on the automatic resume triggered
by pm_complete_with_resume_check(). Fix it.

276142730c PM / sleep: Clear pm_suspend_global_flags upon hibernate
When suspending to RAM, waking up and later suspending to disk,
we gratuitously runtime resume devices after the thaw phase.
This does not occur if we always suspend to RAM or always to disk.

pm_complete_with_resume_check(), which gets called from
pci_pm_complete() among others, schedules a runtime resume
if PM_SUSPEND_FLAG_FW_RESUME is set. The flag is set during
a suspend-to-RAM cycle. It is cleared at the beginning of
the suspend-to-RAM cycle but not afterwards and it is not
cleared during a suspend-to-disk cycle at all. Fix it.

 "Round two of 4.6 merge window patches.

  This is a monster pull request.  I held off on the hfi1 driver updates
  (the hfi1 driver is intimately tied to the qib driver and the new
  rdmavt software library that was created to help both of them) in my
  first pull request.  The hfi1/qib/rdmavt update is probably 90% of
  this pull request.  The hfi1 driver is being left in staging so that
  it can be fixed up in regards to the API that Al and yourself didn't
  like.  Intel has agreed to do the work, but in the meantime, this
  clears out 300+ patches in the backlog queue and brings my tree and
  their tree closer to sync.

  This also includes about 10 patches to the core and a few to mlx5 to
  create an infrastructure for configuring SRIOV ports on IB devices.
  That series includes one patch to the net core that we sent to netdev@
  and Dave Miller with each of the three revisions to the series.  We
  didn't get any response to the patch, so we took that as implicit
  approval.

  Finally, this series includes Intel's new iWARP driver for their x722
  cards.  It's not nearly the beast as the hfi1 driver.  It also has a
  linux-next merge issue, but that has been resolved and it now passes
  just fine.

cf61e2a148 memremap: don't modify flags
These patches implement a MEMREMAP_WC flag for memremap(), which can be
used to obtain writecombine mappings.  This is then used for setting up
dma_coherent_mem regions which use the DMA_MEMORY_MAP flag.

The motivation is to fix an alignment fault on arm64, and the suggestion
to implement MEMREMAP_WC for this case was made at [1].  That particular
issue is handled in patch 4, which makes sure that the appropriate
memset function is used when zeroing allocations mapped as IO memory.

This patch (of 4):

Don't modify the flags input argument to memremap(). MEMREMAP_WB is
already a special case so we can check for it directly instead of
clearing flag bits in each mapper.

41b2715487 kernel/signal.c: add compile-time check for __ARCH_SI_PREAMBLE_SIZE
The value of __ARCH_SI_PREAMBLE_SIZE defines the size (including
padding) of the part of the struct siginfo that is before the union, and
it is then used to calculate the needed padding (SI_PAD_SIZE) to make
the size of struct siginfo equal to 128 (SI_MAX_SIZE) bytes.

Depending on the target architecture and word width it equals to either
3 or 4 times sizeof int.

Since the very beginning we had __ARCH_SI_PREAMBLE_SIZE wrong on the
parisc architecture for the 64bit kernel build.  It's even more
frustrating, because it can easily be checked at compile time if the
value was defined correctly.

This patch adds such a check for the correctness of
__ARCH_SI_PREAMBLE_SIZE in the hope that it will prevent existing and
future architectures from running into the same problem.

I refrained from replacing __ARCH_SI_PREAMBLE_SIZE by offsetof() in
copy_siginfo() in include/asm-generic/siginfo.h, because a) it doesn't
make any difference and b) it's used in the Documentation/kmemcheck.txt
example.

I ran this patch through the 0-DAY kernel test infrastructure and only
the parisc architecture triggered as expected.  That means that this
patch should be OK for all major architectures.

f138556daf mm/mprotect.c: don't imply PROT_EXEC on non-exec fs
The mprotect(PROT_READ) fails when called by the READ_IMPLIES_EXEC
binary on a memory mapped file located on non-exec fs.  The mprotect
does not check whether fs is _executable_ or not.  The PROT_EXEC flag is
set automatically even if a memory mapped file is located on non-exec
fs.  Fix it by checking whether a memory mapped file is located on a
non-exec fs.  If so the PROT_EXEC is not implied by the PROT_READ.  The
implementation uses the VM_MAYEXEC flag set properly in mmap.  Now it is
consistent with mmap.

I did the isolated tests (PT_GNU_STACK X/NX, multiple VMAs, X/NX fs).  I
also patched the official 3.19.0-47-generic Ubuntu 14.04 kernel and it
seems to work.

a5f4db8771 ipc/sem: make semctl setting sempid consistent
As indicated by bug#112271, Linux sets the sempid value upon semctl, and
not only for semop calls.  However, within semctl we only do this for
SETVAL, leaving SETALL without updating the field, and therefore rather
inconsistent behavior when compared to other Unices.

There is really no documentation regarding this and therefore users
should not make assumptions.  With this patch, along with updating
semctl.2 manpages, this scenario should become less ambiguous As such,
set sempid on SETALL cmd.

Also update some in-code documentation, specifying where the sempid is
set.

Passes ltp and custom testcase where a child (fork) does SETALL to the
set.

dde5cf39d4 ubsan: fix tree-wide -Wmaybe-uninitialized false positives
-fsanitize=* options makes GCC less smart than usual and increase number
of 'maybe-uninitialized' false-positives. So this patch does two things:

 * Add -Wno-maybe-uninitialized to CFLAGS_UBSAN which will disable all
   such warnings for instrumented files.

 * Remove CONFIG_UBSAN_SANITIZE_ALL from all[yes|mod]config builds. So
   the all[yes|mod]config build goes without -fsanitize=* and still with
   -Wmaybe-uninitialized.

21b2f44315 kfifo: fix sparse complaints
This patch fix complaints by the sparse tool when using kfifo_put() with
non scalar types like structures (i.e.
drivers/iio/industrialio-event.c).

Casting a pointer to the value and read this pointer instead of directly
casting the value will fix this.

The generated code is equal.
