      Linus Torvalds authored 
      Pull powerpc updates from Ben Herrenschmidt:
 "So here's my next branch for powerpc.  A bit late as I was on vacation
  last week.  It's mostly the same stuff that was in next already, I
  just added two patches today which are the wiring up of lockref for
  powerpc, which for some reason fell through the cracks last time and
  is trivial.

  The highlights are, in addition to a bunch of bug fixes:

   - Reworked Machine Check handling on kernels running without a
     hypervisor (or acting as a hypervisor).  Provides hooks to handle
     some errors in real mode such as TLB errors, handle SLB errors,
     etc...

   - Support for retrieving memory error information from the service
     processor on IBM servers running without a hypervisor and routing
     them to the memory poison infrastructure.

   - _PAGE_NUMA support on server processors

   - 32-bit BookE relocatable kernel support

   - FSL e6500 hardware tablewalk support

   - A bunch of new/revived board support

   - FSL e6500 deeper idle states and altivec powerdown support

  You'll notice a generic mm change here, it has been acked by the
  relevant authorities and is a pre-req for our _PAGE_NUMA support"

      Pull powerpc mremap fix from Ben Herrenschmidt:
 "This is the patch that I had sent after -rc8 and which we decided to
  wait before merging.  It's based on a different tree than my -next
  branch (it needs some pre-reqs that were in -rc4 or so while my -next
  is based on -rc1) so I left it as a separate branch for your to pull.
  It's identical to the request I did 2 or 3 weeks back.

  This fixes crashes in mremap with THP on powerpc.

  The fix however requires a small change in the generic code.  It moves
  a condition into a helper we can override from the arch which is
  harmless, but it *also* slightly changes the order of the set_pmd and
  the withdraw & deposit, which should be fine according to Kirill (who
  wrote that code) but I agree -rc8 is a bit late...

  It was acked by Kirill and Andrew told me to just merge it via powerpc"

      powerpc: Implement arch_spin_is_locked() using arch_spin_value_unlocked() · 7179ba52
      Michael Ellerman authored 
      At a glance these are just the inverse of each other. The one subtlety
is that arch_spin_value_unlocked() takes the lock by value, rather than
as a pointer, which is important for the lockref code.

On the other hand arch_spin_is_locked() doesn't really care, so
implement it in terms of arch_spin_value_unlocked().

      powerpc: Add support for the optimised lockref implementation · 3405d230
      Michael Ellerman authored 
      This commit adds the architecture support required to enable the
optimised implementation of lockrefs.

That's as simple as defining arch_spin_value_unlocked() and selecting
the Kconfig option.

We also define cmpxchg64_relaxed(), because the lockref code does not
need the cmpxchg to have barrier semantics.

Using Linus' test case[1] on one system I see a 4x improvement for the
basic enablement, and a further 1.3x for cmpxchg64_relaxed(), for a
total of 5.3x vs the baseline.

On another system I see more like 2x improvement.

      Loading ipmi_si module while bmc is disconnected, we found the timeout
is longer than 5 secs.  Actually it takes about 3 mins and 20
secs.(HZ=250)

error message as below:
  Dec 12 19:08:59 linux kernel: IPMI BT: timeout in RD_WAIT [ ] 1 retries left

Function wait_for_msg_done() use schedule_timeout_uninterruptible(1) to

usecs from timeout.

 "A respun version of the merges for the pull request previously sent
  with a few additional fixes.  The last two merges were fixed up by
  hand since the branches have moved on and currently have the prior
  merge in them.

  Quite a busy release for the SPI subsystem, mostly in cleanups big and
  small scattered through the stack rather than anything else:

   - New driver for the Broadcom BC63xx HSSPI controller
   - Fix duplicate device registration for ACPI
   - Conversion of s3c64xx to DMAEngine (this pulls in platform and DMA
     changes upon which the transiton depends)
   - Some small optimisations to reduce the amount of time we hold locks
     in the datapath, eliminate some redundant checks and the size of a
     spi_transfer
   - Lots of fixes, cleanups and general enhancements to drivers,
     especially the rspi and Atmel drivers"

      Pull thermal management updates from Zhang Rui:
 "This time, the biggest change is the work of representing hardware
  thermal properties in device tree infrastructure.

  This work includes the introduction of a device tree bindings for
  describing the hardware thermal behavior and limits, and also a parser
  to read and interpret the data, and build thermal zones and thermal
  binding parameters.  It also contains three examples on how to use the
  new representation on sensor devices, using three different drivers to
  accomplish it.  One driver is in thermal subsystem, the TI SoC
  thermal, and the other two drivers are in hwmon subsystem.

  Actually, this would be the first step of the complete work because we
  still need to check other potential drivers to be converted and then
  validate the proposed API.  But the reason why I include it in this
  pull request is that, first, this change does not hurt any others
  without using this approach, second, the principle and concept of this
  change would not break after converting the remaining drivers.  BTW,
  as you can see, there are several points in this change that do not
  belong to thermal subsystem.  Because it has been suggested by Guenter
  R that in such cases, it is recommended to send the complete series
  via one single subsystem.

  Specifics:

   - representing hardware thermal properties in device tree
     infrastructure

   - fix a regression that the imx thermal driver breaks system suspend.

   - introduce ACPI INT3403 thermal driver to retrieve temperature data
     from the INT3403 ACPI device object present on some systems.

   - introduce debug statement for thermal core and step_wise governor.

   - assorted fixes and cleanups for thermal core, cpu cooling, exynos
     thrmal, intel powerclamp and imx thermal driver"

      net/cxgb4: Fix referencing freed adapter · 8b662fe7
      Gavin Shan authored 
      The adapter is freed before we check its flags. It was caused
by commit 144be3d9 ("net/cxgb4: Avoid disabling PCI device for
towice"). The problem was reported by Intel's "0-day" tool.

The patch fixes it to avoid reverting commit 144be3d9.
