Nothing special. The biggest change is adding a couple of command defines and
packing the command data correctly.

* tag 'vmwgfx-fixes-3.14-2014-02-18' of git://people.freedesktop.org/~thomash/linux:
  drm/vmwgfx: Fix command defines and checks
  drm/vmwgfx: Fix possible integer overflow
  drm/vmwgfx: Remove stray const
  drm/vmwgfx: unlock on error path in vmw_execbuf_process()
