Merge branch 'vmwgfx-next' of git://people.freedesktop.org/~thomash/linux into drm-next

A relative large set of various improvements for vmwgfx. Some of them
have been around for a while, some are relatively new, but functionality
should have been tested in our standalone repo.

* 'vmwgfx-next' of git://people.freedesktop.org/~thomash/linux:
  drm/vmwgfx: Bump version patchlevel and date
  drm/vmwgfx: use monotonic event timestamps
  drm/vmwgfx: Unpin the screen object backup buffer when not used
  drm/vmwgfx: Stricter count of legacy surface device resources
  drm/vmwgfx: Use kasprintf
  drm/vmwgfx: Get rid of the device-private suspended member
  drm/vmwgfx: Improve on hibernation
  drm/vmwgfx: Avoid pinning fbdev framebuffers
  drm/vmwgfx: Fix multiple command buffer context use
  drm/vmwgfx: Use the cpu blit utility for framebuffer to screen target blits
  drm/vmwgfx: Add a cpu blit utility that can be used for page-backed bos
  drm/ttm: Export the ttm_k[un]map_atomic_prot API.
  drm/ttm: Clean up kmap_atomic_prot selection code
  drm/vmwgfx: Cursor update fixes
  drm/vmwgfx: Send the correct nonblock option for atomic_commit
  drm/vmwgfx: Move the stdu vblank event to atomic function
  drm/vmwgfx: Move screen object page flip to atomic function
  drm/vmwgfx: Remove drm_crtc_arm_vblank_event from atomic flush
  drm/vmwgfx: Move surface copy cmd to atomic function
  drm/vmwgfx: Avoid iterating over display unit if crtc is available
