 "drm fixes across the board.

  Okay holidays and LCA kinda caught up with me, I thought I'd get some
  of this dequeued last week, but Hobart was sunny and warm and not all
  gloomy and rainy as usual.

  This is a bit large, but not too much considering it's two weeks stuff
  from AMD and Intel.

  core:
   - one locking fix that helps with dynamic suspend/resume races

  i915:
   - mostly GVT updates, GVT was a recent introduction so fixes for it
     shouldn't cause any notable side effects.

  amdgpu:
   - a bunch of fixes for GPUs with a different memory controller design
     that need different firmware.

  exynos:
   - decon regression fixes

  msm:
   - two regression fixes

  etnaviv:
   - a workaround for an mmu bug that needs a lot more work.

  virtio:
   - sparse fix, and a maintainers update"
