Merge tag 'vmwgfx-fixes-3.14-2014-02-05' of git://people.freedesktop.org/~thomash/linux into drm-next

A couple of vmwgfx fixes together with missing bits of legacy device
emulation to facilitate old user-space drivers on new devices.

The shader emulation bits are a bit large, but since they mostly touch the
new device code, regressions are unlikely. I figure the gain of having
this from the start clearly outweighs the risc of adding these bits at
this point.
