In preparation for fixing the BLK path to properly use "directed
pcommit" enable the unit test infrastructure to emit mock "flush"
tables.  Writes to these flush addresses trigger a memory controller to
flush its internal buffers to persistent media, similar to the x86
"pcommit" instruction.

Pull libnvdimm subsystem from Dan Williams:
 "The libnvdimm sub-system introduces, in addition to the
  libnvdimm-core, 4 drivers / enabling modules:

  NFIT:
    Instantiates an "nvdimm bus" with the core and registers memory
    devices (NVDIMMs) enumerated by the ACPI 6.0 NFIT (NVDIMM Firmware
    Interface table).

    After registering NVDIMMs the NFIT driver then registers "region"
    devices.  A libnvdimm-region defines an access mode and the
    boundaries of persistent memory media.  A region may span multiple
    NVDIMMs that are interleaved by the hardware memory controller.  In
    turn, a libnvdimm-region can be carved into a "namespace" device and
    bound to the PMEM or BLK driver which will attach a Linux block
    device (disk) interface to the memory.

  PMEM:
    Initially merged in v4.1 this driver for contiguous spans of
    persistent memory address ranges is re-worked to drive
    PMEM-namespaces emitted by the libnvdimm-core.

    In this update the PMEM driver, on x86, gains the ability to assert
    that writes to persistent memory have been flushed all the way
    through the caches and buffers in the platform to persistent media.
    See memcpy_to_pmem() and wmb_pmem().

  BLK:
    This new driver enables access to persistent memory media through
    "Block Data Windows" as defined by the NFIT.  The primary difference
    of this driver to PMEM is that only a small window of persistent
    memory is mapped into system address space at any given point in
    time.

    Per-NVDIMM windows are reprogrammed at run time, per-I/O, to access
    different portions of the media.  BLK-mode, by definition, does not
    support DAX.

  BTT:
    This is a library, optionally consumed by either PMEM or BLK, that
    converts a byte-accessible namespace into a disk with atomic sector
    update semantics (prevents sector tearing on crash or power loss).

    The sinister aspect of sector tearing is that most applications do
    not know they have a atomic sector dependency.  At least today's
    disk's rarely ever tear sectors and if they do one almost certainly
    gets a CRC error on access.  NVDIMMs will always tear and always
    silently.  Until an application is audited to be robust in the
    presence of sector-tearing the usage of BTT is recommended.

Pull tracing updates from Steven Rostedt:
 "This patch series contains several clean ups and even a new trace
  clock "monitonic raw".  Also some enhancements to make the ring buffer
  even faster.  But the biggest and most noticeable change is the
  renaming of the ftrace* files, structures and variables that have to
  deal with trace events.

  Over the years I've had several developers tell me about their
  confusion with what ftrace is compared to events.  Technically,
  "ftrace" is the infrastructure to do the function hooks, which include
  tracing and also helps with live kernel patching.  But the trace
  events are a separate entity altogether, and the files that affect the
  trace events should not be named "ftrace".  These include:

    include/trace/ftrace.h         ->    include/trace/trace_events.h
    include/linux/ftrace_event.h   ->    include/linux/trace_events.h

  Also, functions that are specific for trace events have also been renamed:

    ftrace_print_*()               ->    trace_print_*()
    (un)register_ftrace_event()    ->    (un)register_trace_event()
    ftrace_event_name()            ->    trace_event_name()
    ftrace_trigger_soft_disabled() ->    trace_trigger_soft_disabled()
    ftrace_define_fields_##call()  ->    trace_define_fields_##call()
    ftrace_get_offsets_##call()    ->    trace_get_offsets_##call()

  Structures have been renamed:

    ftrace_event_file              ->    trace_event_file
    ftrace_event_{call,class}      ->    trace_event_{call,class}
    ftrace_event_buffer            ->    trace_event_buffer
    ftrace_subsystem_dir           ->    trace_subsystem_dir
    ftrace_event_raw_##call        ->    trace_event_raw_##call
    ftrace_event_data_offset_##call->    trace_event_data_offset_##call
    ftrace_event_type_funcs_##call ->    trace_event_type_funcs_##call

  And a few various variables and flags have also been updated.

  This has been sitting in linux-next for some time, and I have not
  heard a single complaint about this rename breaking anything.  Mostly
  because these functions, variables and structures are mostly internal
  to the tracing system and are seldom (if ever) used by anything
  external to that"

Pull tracing fixes from Steven Rostedt:
 "This isn't my 4.2 pull request (yet).  I found a few more bugs that I
  would have sent to fix 4.1, but since 4.1 is already out, I'm sending
  this before sending my 4.2 request (which is ready to go).

  After fixing the previous filter issue reported by Vince Weaver, I
  could not come up with a situation where the operand counter (cnt)
  could go below zero, so I added a WARN_ON_ONCE(cnt < 0).  Vince was
  able to trigger that warn on with his fuzzer test, but didn't have a
  filter input that caused it.

  Later, Sasha Levin was able to trigger that same warning, and was able
  to give me the filter string that triggered it.  It was simply a
  single operation ">".

  I wrapped the filtering code in a userspace program such that I could
  single step through the logic.  With a single operator the operand
  counter can legitimately go below zero, and should be reported to the
  user as an error, but should not produce a kernel warning.  The
  WARN_ON_ONCE(cnt < 0) should be just a "if (cnt < 0) break;" and the
  code following it will produce the error message for the user.

  While debugging this, I found that there was another bug that let the
  pointer to the filter string go beyond the filter string.  This too
  was fixed.

  Finally, there was a typo in a stub function that only gets compiled
  if trace events is disabled but tracing is enabled (I'm not even sure
  that's possible)"

Pull drm updates from Dave Airlie:
 "This is the main drm pull request for v4.2.

  I've one other new driver from freescale on my radar, it's been posted
  and reviewed, I'd just like to get someone to give it a last look, so
  maybe I'll send it or maybe I'll leave it.

  There is no major nouveau changes in here, Ben was working on
  something big, and we agreed it was a bit late, there wasn't anything
  else he considered urgent to merge.

  There might be another msm pull for some bits that are waiting on
  arm-soc, I'll see how we time it.

                This is just the first part of this driver, enough to run
                unaccelerated userspace on. As qemu merges more we'll start
                adding the 3D features for the virgl 3d work.
      - amdgpu:
                a new driver from AMD to driver their newer GPUs. (VI+)

for the 4.2 release.  Given that there have not been any patches
submitted to properly fix these obvious errors, I'm going to disable it

submitted, or, if that never happens, I will remove it from the tree.

Pull ARM SoC DT updates from Kevin Hilman:
 "As usual, quite a few device-tree updates in ARM land.  There was one
  minor churn in DTs due to relicensing under a dual-license, and lots
  of little additions of new peripherals, features etc, but nothing
  really exciting to call to your attention.  Some higlights, focsuing
  on support for new SoCs and boards:

   - AT91: new boards: Overkiz,  Acme Systems' Arietta G25
   - tegra: HDA support
   - bcm: new platforms: Buffalo WXR-1900DHP, SmartRG SR400ac, ASUS
     RT-AC87U
   - mvebu: new platforms: Compulab CM-A510, Armada 385-based Linksys
     boards, DLink DNS-327L
   - OMAP: new platforms: Baltos IR5221, LogicPD Torpedo, Toby-Churchill
     SL50
   - ARM: added support for Juno r1 board
   - sunxi: A33 SoC support; new boards: A23 EVB, SinA33, GA10H-A33,
     Mele A1000G
   - imx: i.MX7D SoC support; new boards: Armadeus Systems APF6,
     Gateworks GW5510, and aristainetos2 boards
   - hisilicon: hi6220 SoC support; new boards: 96boards hikey"
