      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 touches some "of" stuff, acks are in place except for the fixes
  to the build in various configs,t hat I just applied.

  Summary:

  New drivers:
      - virtio-gpu:
                KMS only pieces of driver for virtio-gpu in qemu.
                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+)
                It contains a new cleaner userspace API, and is a clean
                break from radeon moving forward, that AMD are going to
                concentrate on. It also contains a set of register headers
                auto generated from AMD internal database.

  core:
      - atomic modesetting API completed, enabled by default now.
      - Add support for mode_id blob to atomic ioctl to complete interface.
      - bunch of Displayport MST fixes
      - lots of misc fixes.

  panel:
      - new simple panels
      - fix some long-standing build issues with bridge drivers

  radeon:
      - VCE1 support
      - add a GPU reset counter for userspace
      - lots of fixes.

  amdkfd:
      - H/W debugger support module
      - static user-mode queues
      - support killing all the waves when a process terminates
      - use standard DECLARE_BITMAP

  i915:

      - enable cmd parser on haswell
      - cdclk handling fixes
      - gen8 dynamic pte allocation
      - lots of atomic conversion work

  exynos:
      - Add atomic modesetting support
      - Add iommu support
      - Consolidate drm driver initialization
      - and MIC, DECON and MIPI-DSI support for exynos5433

  omapdrm:
      - atomic modesetting support (fixes lots of things in rewrite)

  tegra:
      - DP aux transaction fixes
      - iommu support fix

  msm:
      - adreno a306 support
      - various dsi bits
      - various 64-bit fixes
      - NV12MT support

  rcar-du:
      - atomic and misc fixes

  sti:
      - fix HDMI timing complaince

  tilcdc:
      - use drm component API to access tda998x driver
      - fix module unloading

  qxl:
      - stability fixes"
