Merge branch 'vmwgfx-fixes-3.18' of git://people.freedesktop.org/~thomash/linux

Browse Source 
A critical 3.18 regression fix from Rob, (thanks!)
A fix to avoid advertizing modes we can't support from Sinclair
  (welcome Sinclair!)
and a fix for an incorrect  hash key computation from me that is
  completely harmless, but can wait 'til the next merge window if necessary.
  (I can't really bother stable with this one).

* 'vmwgfx-fixes-3.18' of git://people.freedesktop.org/~thomash/linux:
  drm/vmwgfx: Filter out modes those cannot be supported by the current VRAM size.
  drm/vmwgfx: Fix hash key computation
  drm/vmwgfx: fix lock breakage
