4f1f653a68 watchdog: s3c2410_wdt: use syscon regmap interface to configure pmu register 
Add device tree support for exynos5250 and 5420 SoCs and use syscon regmap interface
to configure AUTOMATIC_WDT_RESET_DISABLE and MASK_WDT_RESET_REQUEST registers of PMU
to mask/unmask enable/disable of watchdog in probe and s2r scenarios.

8832b20093 watchdog: davinci: reuse driver for keystone arch 
The keystone arch uses the same IP watchdog, so add "ti,keystone-wdt"
compatible and correct identity.

The Keystone arch is using clocks in DT and source clock for watchdog
has to be specified, so add this to binding.

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"

2d2e7d195b spi: Updates for v3.14 
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.

15333539a9 regulator: Updates for v3.14 
A respin of the merges in the previous pull request with one extra fix.
 A quiet release for the regulator API, quite a large number of small
 improvements all over but other than the addition of new drivers for the
 AS3722 and MAX14577 there is nothing of substantial non-local impact.

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"

09da8dfa98 ACPI and power management updates for 3.14-rc1 
- ACPI core changes to make it create a struct acpi_device object for every
    device represented in the ACPI tables during all namespace scans regardless
    of the current status of that device.  In accordance with this, ACPI hotplug
    operations will not delete those objects, unless the underlying ACPI tables
    go away.
 
  - On top of the above, new sysfs attribute for ACPI device objects allowing
    user space to check device status by triggering the execution of _STA for
    its ACPI object.  From Srinivas Pandruvada.
 
  - ACPI core hotplug changes reducing code duplication, integrating the
    PCI root hotplug with the core and reworking container hotplug.
 
  - ACPI core simplifications making it use ACPI_COMPANION() in the code
    "glueing" ACPI device objects to "physical" devices.
 
  - ACPICA update to upstream version 20131218.  This adds support for the
    DBG2 and PCCT tables to ACPICA, fixes some bugs and improves debug
    facilities.  From Bob Moore, Lv Zheng and Betty Dall.
 
  - Init code change to carry out the early ACPI initialization earlier.
    That should allow us to use ACPI during the timekeeping initialization
    and possibly to simplify the EFI initialization too.  From Chun-Yi Lee.
 
  - Clenups of the inclusions of ACPI headers in many places all over from
    Lv Zheng and Rashika Kheria (work in progress).
 
  - New helper for ACPI _DSM execution and rework of the code in drivers
    that uses _DSM to execute it via the new helper.  From Jiang Liu.
 
  - New Win8 OSI blacklist entries from Takashi Iwai.
 
  - Assorted ACPI fixes and cleanups from Al Stone, Emil Goode, Hanjun Guo,
    Lan Tianyu, Masanari Iida, Oliver Neukum, Prarit Bhargava, Rashika Kheria,
    Tang Chen, Zhang Rui.
 
  - intel_pstate driver updates, including proper Baytrail support, from

Merge tag 'pm+acpi-3.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull ACPI and power management updates from Rafael Wysocki:
 "As far as the number of commits goes, the top spot belongs to ACPI
  this time with cpufreq in the second position and a handful of PM
  core, PNP and cpuidle updates.  They are fixes and cleanups mostly, as
  usual, with a couple of new features in the mix.

  The most visible change is probably that we will create struct
  acpi_device objects (visible in sysfs) for all devices represented in
  the ACPI tables regardless of their status and there will be a new
  sysfs attribute under those objects allowing user space to check that
  status via _STA.

  Consequently, ACPI device eject or generally hot-removal will not
  delete those objects, unless the table containing the corresponding
  namespace nodes is unloaded, which is extremely rare.  Also ACPI
  container hotplug will be handled quite a bit differently and cpufreq
  will support CPU boost ("turbo") generically and not only in the
  acpi-cpufreq driver.

  Specifics:

   - ACPI core changes to make it create a struct acpi_device object for
     every device represented in the ACPI tables during all namespace
     scans regardless of the current status of that device.  In
     accordance with this, ACPI hotplug operations will not delete those
     objects, unless the underlying ACPI tables go away.

   - On top of the above, new sysfs attribute for ACPI device objects
     allowing user space to check device status by triggering the
     execution of _STA for its ACPI object.  From Srinivas Pandruvada.

   - ACPI core hotplug changes reducing code duplication, integrating
     the PCI root hotplug with the core and reworking container hotplug.

   - ACPI core simplifications making it use ACPI_COMPANION() in the

entirely of new platform/driver support. There are some conversions of
 existing drivers to the common-clock Device Tree binding, and a few
 non-critical fixes to the framework.
 
 Due to an entirely unnecessary cyclical dependency with the arm-soc tree
 this pull request is broken into two pieces. The second piece will be
 sent out after arm-soc sends you the pull request that merged in core
 support for the HiSilicon 3620 platform. That same pull request from
 arm-soc depends on this pull request to merge in those HiSilicon bits
 without causing build failures.

0ba3307a8e ARM: driver updates for 3.14 
Updates of SoC-near drivers and other driver updates that makes more sense to
 take through our tree.
 
 The largest part of this is a conversion of device registration for some
 renesas shmobile/sh devices over to use resources. This has required
 coordination with the corresponding arch/sh changes, and we've agreed
 to merge the arch/sh changes through our tree.
 
 Added in this branch is support for Trusted Foundations secure firmware,
 which is what is used on many of the commercial Nvidia Tegra products
 that are in the market, including the Nvidia Shield. The code is local
 to arch/arm at this time since it's uncertain whether it will be shared
 with arm64 longer-term, if needed we will refactor later.
 
 A couple of new RTC drivers used on ARM boards, merged through our tree
 on request by the RTC maintainer.
 
 ... plus a bunch of smaller updates across the board, gpio conversions

f2c73464d7 ARM: SoC cleanups for 3.14 
This is the branch where we usually queue up cleanup efforts, moving
 drivers out of the architecture directory, header file restructuring,
 etc. Sometimes they tangle with new development so it's hard to keep it
 strictly to cleanups.
 
 Some of the things included in this branch are:
 
 * Atmel SAMA5 conversion to common clock
 * Reset framework conversion for tegra platforms
  - Some of this depends on tegra clock driver reworks that are shared with Mike
    Turquette's clk tree.
 * Tegra DMA refactoring, which are shared branches with the DMA tree.
 * Removal of some header files on exynos to prepare for multiplatform

 There are also a couple of stable-marked patches for mvebu -- they came in

integrity checks and (ii) enable the backup GPT header to be used in
situations where the primary one is corrupted.  This last "feature" is not
obvious and needs to be properly documented in the kernel-parameters
document.

7984754b99 kexec: add sysctl to disable kexec_load 
For general-purpose (i.e.  distro) kernel builds it makes sense to build
with CONFIG_KEXEC to allow end users to choose what kind of things they
want to do with kexec.  However, in the face of trying to lock down a
system with such a kernel, there needs to be a way to disable kexec_load
(much like module loading can be disabled).  Without this, it is too easy
for the root user to modify kernel memory even when CONFIG_STRICT_DEVMEM
and modules_disabled are set.  With this change, it is still possible to
load an image for use later, then disable kexec_load so the image (or lack
of image) can't be altered.

The intention is for using this in environments where "perfect"
enforcement is hard.  Without a verified boot, along with verified
modules, and along with verified kexec, this is trying to give a system a
better chance to defend itself (or at least grow the window of
discoverability) against attack in the face of a privilege escalation.

In my mind, I consider several boot scenarios:

1) Verified boot of read-only verified root fs loading fd-based
   verification of kexec images.
2) Secure boot of writable root fs loading signed kexec images.
3) Regular boot loading kexec (e.g. kcrash) image early and locking it.
4) Regular boot with no control of kexec image at all.

1 and 2 don't exist yet, but will soon once the verified kexec series has
landed.  4 is the state of things now.  The gap between 2 and 4 is too
large, so this change creates scenario 3, a middle-ground above 4 when 2
and 1 are not possible for a system.

Add %pad to be able to emit them without the cast.

57ea8171d2 mm: documentation: remove hopelessly out-of-date locking doc 
Documentation/vm/locking is a blast from the past.  In the entire git
history, it has had precisely Three modifications.  Two of those look to
be pure renames, and the third was from 2005.

The doc contains such gems as:

> The page_table_lock is grabbed while holding the
> kernel_lock spinning monitor.

> Page stealers hold kernel_lock to protect against a bunch of
> races.

Or this which talks about mmap_sem:

> 4. The exception to this rule is expand_stack, which just
>    takes the read lock and the page_table_lock, this is ok
>    because it doesn't really modify fields anybody relies on.

expand_stack() doesn't take any locks any more directly, and the
mmap_sem acquisition was long ago moved up in to the page fault code
itself.

It could be argued that we need to rewrite this, but it is dangerous to
leave it as-is.  It will confuse more people than it helps.

Merge tag 'for-f2fs-3.14' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs

Pull f2fs updates from Jaegeuk Kim:
 "In this round, a couple of sysfs entries were introduced to tune the
  f2fs at runtime.

  In addition, f2fs starts to support inline_data and improves the
  read/write performance in some workloads by refactoring bio-related
  flows.

  This patch-set includes the following major enhancement patches.
   - support inline_data
   - refactor bio operations such as merge operations and rw type
     assignment
   - enhance the direct IO path
   - enhance bio operations
   - truncate a node page when it becomes obsolete
   - add sysfs entries: small_discards, max_victim_search, and
     in-place-update
   - add a sysfs entry to control max_victim_search

  The other bug fixes are as follows.
   - fix a bug in truncate_partial_nodes
   - avoid warnings during sparse and build process
   - fix error handling flows
