Merge branch 'vmwgfx-fixes-3.13' of git://people.freedesktop.org/~thomash/linux into drm-fixes

Below is a fix for a false lockep warning,
and the vmwgfx prime implementation.

* 'vmwgfx-fixes-3.13' of git://people.freedesktop.org/~thomash/linux:
  drm/vmwgfx: Make vmwgfx dma buffers prime aware
  drm/vmwgfx: Make surfaces prime-aware
  drm/vmwgfx: Hook up the prime ioctls
  drm/ttm: Add a minimal prime implementation for ttm base objects
  drm/vmwgfx: Fix false lockdep warning
  drm/ttm: Allow execbuf util reserves without ticket
