Merge tag 'pwm/for-3.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm

Pull pwm changes from Thierry Reding:
 "The majority of these changes are cleanups and fixes across all
  drivers.  Redundant error messages are removed and more PWM
  controllers set the .can_sleep flag to signal that they can't be used
  in atomic context.

  Support is added for the Broadcom Kona family of SoCs and the Intel
  LPSS driver can now probe PCI devices in addition to ACPI devices.
  Upon shutdown, the pwm-backlight driver will now power off the
  backlight.  It also uses the new descriptor-based GPIO API for more
  concise GPIO handling.

  A large chunk of these changes also converts platforms to use the
  lookup mechanism rather than relying on the global number space to
  reference PWM devices.  This is largely in preparation for more
  unification and cleanups in future patches.  Eventually it will allow
  the legacy PWM API to be removed"

Pull block layer fixes from Jens Axboe:
 "Final small batch of fixes to be included before -rc1.  Some general
  cleanups in here as well, but some of the blk-mq fixes we need for the
  NVMe conversion and/or scsi-mq.  The pull request contains:

   - Support for not merging across a specified "chunk size", if set by
     the driver.  Some NVMe devices perform poorly for IO that crosses
     such a chunk, so we need to support it generically as part of
     request merging avoid having to do complicated split logic.  From
     me.

   - Bump max tag depth to 10Ki tags.  Some scsi devices have a huge
     shared tag space.  Before we failed with EINVAL if a too large tag
     depth was specified, now we truncate it and pass back the actual
     value.  From me.

   - Various blk-mq rq init fixes from me and others.

Pull powerpc updates from Ben Herrenschmidt:
 "Here is the bulk of the powerpc changes for this merge window.  It got
  a bit delayed in part because I wasn't paying attention, and in part
  because I discovered I had a core PCI change without a PCI maintainer
  ack in it.  Bjorn eventually agreed it was ok to merge it though we'll
  probably improve it later and I didn't want to rebase to add his ack.

  There is going to be a bit more next week, essentially fixes that I
  still want to sort through and test.

  The biggest item this time is the support to build the ppc64 LE kernel
  with our new v2 ABI.  We previously supported v2 userspace but the
  kernel itself was a tougher nut to crack.  This is now sorted mostly
  thanks to Anton and Rusty.

  We also have a fairly big series from Cedric that add support for
  64-bit LE zImage boot wrapper.  This was made harder by the fact that
  traditionally our zImage wrapper was always 32-bit, but our new LE
  toolchains don't really support 32-bit anymore (it's somewhat there
  but not really "supported") so we didn't want to rely on it.  This
  meant more churn that just endian fixes.

  This brings some more LE bits as well, such as the ability to run in
  LE mode without a hypervisor (ie. under OPAL firmware) by doing the
  right OPAL call to reinitialize the CPU to take HV interrupts in the
  right mode and the usual pile of endian fixes.

  There's another series from Gavin adding EEH improvements (one day we
  *will* have a release with less than 20 EEH patches, I promise!).

  Another highlight is the support for the "Split core" functionality on
  P8 by Michael.  This allows a P8 core to be split into "sub cores" of
  4 threads which allows the subcores to run different guests under KVM
  (the HW still doesn't support a partition per thread).

  And then the usual misc bits and fixes ..."

target a fairly narrow group of systems. i.e. old enough to not have
HPWMI_FEATURE_QUERY 0xd, but new enough to have HPWMI_BIOS_QUERY 0x9.
This group may be further limited if some systems respond with something
other than 4 to non-existant feature queries.

These keys generate the sofar unused 28 - 31 hotkey scancodes.

This patch moves data allocated using kzalloc to managed data allocated
using devm_kzalloc and cleans now unnecessary kfrees in probe and remove
functions. The label sysfs_failed is removed as it is no longer
required.  Also, linux/device.h is added to make sure the devm_*()
routine declarations are unambiguously available.

The following Coccinelle semantic patch was used for making the change:

The Lenovo Yoga 2 11 always reports everything as blocked, causing userspace
to not even try to use the wlan / bluetooth even though they work fine.

Note this patch also removes the "else priv->rfk[i] = NULL;" bit of the
rfkill initialization, it is not necessary as the priv struct is allocated
with kzalloc.

Merge leftovers from Andrew Morton:
 "A few leftovers: ocfs2, gcov, RTC"

* emailed patches from Andrew Morton <akpm@linux-foundation.org>:
  rtc: s5m: consolidate two device type switch statements
  rtc: s5m: add support for S2MPS14 RTC
  rtc: s5m: support different register layout
  rtc: s5m: use shorter time of register update
  rtc: s5m: remove undocumented time init on first boot
  mfd/rtc: sec/s5m: rename SEC* symbols to S5M
  gcov: add support for GCC 4.9
  ocfs2/o2net: incorrect to terminate accepting connections loop upon rejecting an invalid one

In probe the configuration of driver for different chipsets was done in
two switch (pdata->device_type) statements.  Consolidate them into one
switch statement to increase code readability.

Additionally check the return value of regmap_irq_get_virq and exit
probe on error.

Add support for S2MPS14 to the rtc-s5m driver.  Differences in S2MPS14
(in comparison to S5M8767):

 - Layout of registers
 - Lack of century support for time and alarms (7 registers used for
   storing time/alarm)
 - Two buffer control registers: WUDR and RUDR
 - No register for enabling writing time
 - RTC interrupts are reported in main PMIC I2C device

Remove the code for initializing time if this is first boot.

The code for detecting first boot uses undocumented field RTC_TCON in
RTC_UDR_CON register.  According to S5M8767's datasheet this field is
reserved.  On S2MPS14 it is not documented at all.

On device first boot the registers will be initialized with reset value
(2000-01-01 00:00:00).

The code might work on S5M8763 but still this does not look like a task
for RTC driver.

This patch handles the gcov-related changes in GCC 4.9:

  A new counter (time profile) is added. The total number is 9 now.

  A new profile merge function __gcov_merge_time_profile is added.

See gcc/gcov-io.h and libgcc/libgcov-merge.c

For the first change, the layout of struct gcov_info is affected.

For the second one, a dummy function is added to kernel/gcov/base.c
similarly.

Right now when people try to report issues in the kernel they send stack
dumps to eachother, which looks something like this:

  [    6.906437]  [<ffffffff811f0e90>] ? backtrace_test_irq_callback+0x20/0x20
  [    6.907121]  [<ffffffff84388ce8>] dump_stack+0x52/0x7f
  [    6.907640]  [<ffffffff811f0ec8>] backtrace_regression_test+0x38/0x110
  [    6.908281]  [<ffffffff813596a0>] ? proc_create_data+0xa0/0xd0
  [    6.908870]  [<ffffffff870a8040>] ? proc_modules_init+0x22/0x22
  [    6.909480]  [<ffffffff810020c2>] do_one_initcall+0xc2/0x1e0
  [...]

However, most of the text you get is pure garbage.

The only useful thing above is the function name.  Due to the amount of
different kernel code versions and various configurations being used,
the kernel address and the offset into the function are not really
helpful in determining where the problem actually occured.

Too often the result of someone looking at a stack dump is asking the
person who sent it for a translation for one or more 'addr2line'
translations.  Which slows down the entire process of debugging the
issue (and really annoying).

The decode_stacktrace script is an attempt to make the output more
useful and easy to work with by translating all kernel addresses in the
stack dump into line numbers.  Which means that the stack dump would
look like this:

  [  635.148361]  dump_stack (lib/dump_stack.c:52)
  [  635.149127]  warn_slowpath_common (kernel/panic.c:418)
  [  635.150214]  warn_slowpath_null (kernel/panic.c:453)
  [  635.151031]  _oalloc_pages_slowpath+0x6a/0x7d0
  [  635.152171]  ? zone_watermark_ok (mm/page_alloc.c:1728)
  [  635.152988]  ? get_page_from_freelist (mm/page_alloc.c:1939)
  [  635.154766]  __alloc_pages_nodemask (mm/page_alloc.c:2766)

It's pretty obvious why this is better than the previous stack dump
before.

Usage is pretty simple:

        ./decode_stacktrace.sh [vmlinux] [base path]

Where vmlinux is the vmlinux to extract line numbers from and base path
is the path that points to the root of the build tree, for example:

        ./decode_stacktrace.sh vmlinux /home/sasha/linux/ < input.log > output.log

The stack trace should be piped through it (I, for example, just pipe
the output of the serial console of my KVM test box through it).
