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.

  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
