7e21774db5 The first half of the clk framework pull request is made up almost 
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
 for davinci, etc.

903a9f77d1 ARM: SoC board updates for 3.14 
This branch is reducing in size for every release since most board-related
 changes have started happening in devicetrees now. Still, we have some things
 going on here.
 
 * Renesas platforms are still adding a bit more legacy device support, something
   that should trail off shortly as they move to full DT.
 * We group most defconfig updates into this branch out of old habits
 * Removal of legacy OMAP2 platforms over to DT continues, and a handful of old
   code is being removed here.

9b6d351a75 ARM: SoC DT updates for 3.14 
DT and DT-conversion-related changes for various ARM platforms. Most
 of these are to enable various devices on various boards, etc, and not
 necessarily worth enumerating.
 
 New boards and systems continue to come in as new devicetree files that
 don't require corresponding C changes any more, which is indicating that
 the system is starting to work fairly well.
 
 A few things worth pointing out:
 
 * ST Ericsson ux500 platforms have made the major push to move over to fully
   support the platform with DT.
 * Renesas platforms continue their conversion over from legacy platform devices
   to DT-based for hardware description.

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

Merge tag 'cleanup-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM SoC cleanups from Olof Johansson:
 "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"

93abdb7785 ARM: SoC non-critical fixes for 3.14 
As usual, we have a batch of fixes that weren't considered significant
 enough to warrant going into the later -rcs for previous release, so
 they are queued up on this branch.
 
 A handful of these are for various DT fixups for Samsung platforms,
 and a handful of other minor things.
 
 There are also a couple of stable-marked patches for mvebu -- they came in
 quite late and we decided to keep them deferred until the first -stable
 release to get more coverage instead of squeezing them into 3.13.

cf0744021c firmware/dmi_scan: generalize for use by other archs 
This patch makes a couple of changes to the SMBIOS/DMI scanning
code so it can be used on other archs (such as ARM and arm64):
(a) wrap the calls to ioremap()/iounmap(), this allows the use of a
    flavor of ioremap() more suitable for random unaligned access;
(b) allow the non-EFI fallback probe into hardcoded physical address
    0xF0000 to be disabled.

Convert cache.h to use uapi/linux/kernel.h instead

Convert the ALIGN macro to __ALIGN_KERNEL.

printk_once only sets the bool variable tested

Neaten the alignment so it matches the rest of the

309381feae mm: dump page when hitting a VM_BUG_ON using VM_BUG_ON_PAGE 
Most of the VM_BUG_ON assertions are performed on a page.  Usually, when
one of these assertions fails we'll get a BUG_ON with a call stack and
the registers.

I've recently noticed based on the requests to add a small piece of code
that dumps the page to various VM_BUG_ON sites that the page dump is
quite useful to people debugging issues in mm.

This patch adds a VM_BUG_ON_PAGE(cond, page) which beyond doing what
VM_BUG_ON() does, also dumps the page before executing the actual
BUG_ON.

can be solved by just dropping the legacy hwmod data for interrupts
for v3.14.

84621c9b18 Features: 
- FIFO event channels. Key advantages: support for over 100,000 events (2^17),
    16 different event priorities, improved fairness in event latency through
    the use of FIFOs.
  - Xen PVH support. "It’s a fully PV kernel mode, running with paravirtualized
    disk and network, paravirtualized interrupts and timers, no emulated devices
    of any kind (and thus no qemu), no BIOS or legacy boot — but instead of
    requiring PV MMU, it uses the HVM hardware extensions to virtualize the
    pagetables, as well as system calls and other privileged operations."
    (from "The Paravirtualization Spectrum, Part 2: From poles to a spectrum")
 Bug-fixes:
  - Fixes in balloon driver (refactor and make it work under ARM)
  - Allow xenfb to be used in HVM guests.
  - Allow xen_platform_pci=0 to work properly.
  - Refactors in event channels.

Pull Xen updates from Konrad Rzeszutek Wilk:
 "Two major features that Xen community is excited about:

  The first is event channel scalability by David Vrabel - we switch
  over from an two-level per-cpu bitmap of events (IRQs) - to an FIFO
  queue with priorities.  This lets us be able to handle more events,
  have lower latency, and better scalability.  Good stuff.

  The other is PVH by Mukesh Rathor.  In short, PV is a mode where the
  kernel lets the hypervisor program page-tables, segments, etc.  With
  EPT/NPT capabilities in current processors, the overhead of doing this
  in an HVM (Hardware Virtual Machine) container is much lower than the
  hypervisor doing it for us.

  In short we let a PV guest run without doing page-table, segment,
  syscall, etc updates through the hypervisor - instead it is all done
  within the guest container.  It is a "hybrid" PV - hence the 'PVH'
  name - a PV guest within an HVM container.

  The major benefits are less code to deal with - for example we only
  use one function from the the pv_mmu_ops (which has 39 function
  calls); faster performance for syscall (no context switches into the
  hypervisor); less traps on various operations; etc.

  It is still being baked - the ABI is not yet set in stone.  But it is
  pretty awesome and we are excited about it.

  Lastly, there are some changes to ARM code - you should get a simple
  conflict which has been resolved in #linux-next.

  In short, this pull has awesome features.

  Features:
   - FIFO event channels.  Key advantages: support for over 100,000
     events (2^17), 16 different event priorities, improved fairness in
     event latency through the use of FIFOs.
   - Xen PVH support.  "It’s a fully PV kernel mode, running with
     paravirtualized disk and network, paravirtualized interrupts and
     timers, no emulated devices of any kind (and thus no qemu), no BIOS
     or legacy boot — but instead of requiring PV MMU, it uses the HVM
     hardware extensions to virtualize the pagetables, as well as system
     calls and other privileged operations." (from "The

Update X86 code to use NUMA_NO_NODE instead of MAX_NUMNODES while
calling memblock APIs, because memblock API will be changed to use
NUMA_NO_NODE and will produce warning during boot otherwise.

Switch to memblock interfaces for early memory allocator instead of
bootmem allocator.  No functional change in beahvior than what it is in
current code from bootmem users points of view.

Archs already converted to NO_BOOTMEM now directly use memblock
interfaces instead of bootmem wrappers build on top of memblock.  And
the archs which still uses bootmem, these new apis just fallback to
exiting bootmem APIs.

26f09e9b3a mm/memblock: add memblock memory allocation apis 
Introduce memblock memory allocation APIs which allow to support PAE or
LPAE extension on 32 bits archs where the physical memory start address
can be beyond 4GB.  In such cases, existing bootmem APIs which operate
on 32 bit addresses won't work and needs memblock layer which operates
on 64 bit addresses.

So we add equivalent APIs so that we can replace usage of bootmem with
memblock interfaces.  Architectures already converted to NO_BOOTMEM use
these new memblock interfaces.  The architectures which are still not
converted to NO_BOOTMEM continue to function as is because we still
maintain the fal lback option of bootmem back-end supporting these new
interfaces.  So no functional change as such.

In long run, once all the architectures moves to NO_BOOTMEM, we can get
rid of bootmem layer completely.  This is one step to remove the core
code dependency with bootmem and also gives path for architectures to
move away from bootmem.

The proposed interface will became active if both CONFIG_HAVE_MEMBLOCK
and CONFIG_NO_BOOTMEM are specified by arch.  In case
!CONFIG_NO_BOOTMEM, the memblock() wrappers will fallback to the
existing bootmem apis so that arch's not converted to NO_BOOTMEM
continue to work as is.

The meaning of MEMBLOCK_ALLOC_ACCESSIBLE and MEMBLOCK_ALLOC_ANYWHERE
is kept same.

5b6e529521 x86: memblock: set current limit to max low memory address 
The memblock current limit value is used to limit early boot memory
allocations below max low memory address by default, as the kernel can
access only to the low memory.

Hence, set memblock current limit value to the max mapped low memory
address instead of max mapped memory address.

aec6a8889a mm, show_mem: remove SHOW_MEM_FILTER_PAGE_COUNT 
Commit 4b59e6c473 ("mm, show_mem: suppress page counts in
non-blockable contexts") introduced SHOW_MEM_FILTER_PAGE_COUNT to
suppress PFN walks on large memory machines.  Commit c78e93630d ("mm:
do not walk all of system memory during show_mem") avoided a PFN walk in
the generic show_mem helper which removes the requirement for
SHOW_MEM_FILTER_PAGE_COUNT in that case.

This patch removes PFN walkers from the arch-specific implementations
that report on a per-node or per-zone granularity.  ARM and unicore32
still do a PFN walk as they report memory usage on each bank which is a
much finer granularity where the debugging information may still be of
use.  As the remaining arches doing PFN walks have relatively small
amounts of memory, this patch simply removes SHOW_MEM_FILTER_PAGE_COUNT.

d4371f94bc sound updates for 3.14-rc1 
It was holiday season, so no wonder that there are little changes in
 framework level, although diffstat shows quite many changes spreaded
 over sound/* directories.  Most of changes are cleanups, code
 refactoring and fixes.
 
 Some highlights:
 
 - Removal of OSS sleep_on usages by Arnd
 
 - Simplified memalloc helper codes, drop obsoleted features;
   now it's built into PCM driver instead of an individual module
 
 - Warn if PCM buffer preallocation fails, which will show page
   allocation issues more clearly
 
 - Compress offload API updates for sample rates by Vinod
 
 - PCM glitch workaround on ctxfi emu20k1 by Sarah
 
 - Drop cs46xx DSP blobs, using firmware loader now
 
 - USB-audio quitks for Plantronics Gamecom 780, Creative VF0420,
   and Focusrite Saffire 6
 
 HD-audio specifics:
 
 - Standardize Kconfigs of HD-audio codec drivers;
   now "make localmodconfig" recognizes configs properly (finally!)
 
 - Parallel PM implementation by Mengdong
 
 - BayleyBay/ValleyView2 board fixups
 
 - Broadwell audio support
 
 - Runtime PM improvement (PantherPoint, etc)
 
 - Quirks: Dell subwooer, Gigabyte mobo jack detection oddity,
   Dell AiO click noise fixes, Dell headset mic fixes, etc
 
 - Automatic bind with HDMI codec parser without generic parser
 
 - More AD codec fixes (since 3.12 regression) including the automatic
   stereo mix support
 
 - Common Thinkpad ACPI helper for Realtek and Conexant codecs
 
 ASoC specifics:
 
 - Update to the generic DMA code to support deferred probe and managed
   resources
 
 - New drivers for BCM2835 (used in Raspberry Pi), Tegra with MAX98090
   and Analog Devices AXI I2S and S/PDIF controller IPs
 
 - Device tree support for the simple card, max98090 and cs42l52
 
 - Conversion of the Samsung drivers to native dmaengine, making them
   multiplatform compatible and hopefully helping keep them more modern
   and up to date.
 
 - More regmap conversions, including a very welcome one for twl6040
   from Peter Ujfalusi
 
 - A big overhaul of the DaVinci drivers also from Peter Ujfalusi
 
 - Lots of DMA updates from Lars-Peter
 
 - Improvements to the constraints handling code from Lars-Peter
 
 - A very helpful conversion of the TWL4030 driver to regmap from Peter
 
 - A new driver for the Freescale ESAI controller from Nicolin Chen
 
 - Conversion of some of the drivers to use params_width()
 
 - Extensions to DPCM for use with compressed audio from Liam
