Merge branch 'drm-vmware-next' into drm-core-next 

* drm-vmware-next:
  drm/vmwgfx: Bump driver minor
  vmwgfx: Move function declaration to correct header
  drm/vmwgfx: Treat out-of-range initial width and height as host errors
  vmwgfx: Pick up the initial size from the width and height regs
  vmwgfx: Add page flip support
  vmwgfx: Pipe fence out of screen object dirty functions
  vmwgfx: Make it possible to get fence from execbuf
  vmwgfx: Clean up pending event references to struct drm_file objects on close
  vmwgfx: Rework fence event action
