Pull i916 drm fixes from Rodrigo Vivi:
"Since Dave is on paternity leave we are sending drm/i915 fixes for
v4.14-rc1 directly to you as he had asked us to do.
The most critical ones are the GPU reset fix for gen2-4 and GVT fix
for a regression that is blocking gvt init to work on your tree.
The rest is general fixes for patches coming from drm-next"
