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 ..."

commit 997daa1b (i.e. hp-wmi: detect
"2009 BIOS or later"). Older systems that do not have the 2009 BIOS query
method respond with a dummy value, in this case 4. Using that, we can
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.

The T440s user guide says that when Fn-lock is not active, the *40s' F9 - F12

  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.

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.

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).

The kernel has no concept of capabilities with respect to inodes; inodes
exist independently of namespaces.  For example, inode_capable(inode,
CAP_LINUX_IMMUTABLE) would be nonsense.

This patch changes inode_capable to check for uid and gid mappings and
renames it to capable_wrt_inode_uidgid, which should make it more
obvious what it does.

Fixes CVE-2014-4014.

This patch adds platform code for Intel Merrifield.
Since the watchdog is not part of SFI table, we have no other option but
to manually register watchdog's platform device (argh!).

Add initial Intel MID watchdog driver support.

This driver is an initial implementation of generic Intel MID watchdog
driver. Currently it supports Intel Merrifield platform.

Implementation of ->set_timeout() is supposed to set 'timeout' field of 'struct
watchdog_device' passed to it. sp805 was rather setting this in a local
variable. Fix it.

Basically, this patch does the following:
1. Move the codes of parsing boot parameters from setup-common.c
   to driver. In this way, code reader can know directly that
   there are boot parameters that can change the timeout.
2. Make boot parameter 'booke_wdt_period' effective.
   currently, when driver is loaded, default timeout is always
   being used in stead of booke_wdt_period.
3. Wrap up the watchdog timeout in device struct and clean up
   unnecessary codes.

All three iop variants we support in Linux (iop32x, iop33x and
iop13xx) seem to have support for the watchdog hardware, but this
driver fails to build for the first two of these because it
uses the IOP13XX_WDTCR_IB_RESET macro that is only defined for
iop13xx.

This clarifies the dependency in Kconfig to avoid randconfig
build errors. It is unlikely that anyone will ever miss support
for this driver on the ancient iop3xx platforms, so we don't
need to bother trying to fix it properly.

This commit adds support for the Armada 375 and Armada 380 SoCs.

This SoC variant has a second RSTOUT register, in addition to the already
existent, which is shared with the system-controller. To handle this RSTOUT,
we introduce a new MMIO register 'rstout_mask' to be required on
'armada-{375,380}-watchdog' new compatible string.
