[Intel-gfx] [PULL] drm-intel-fixes

[Jani Nikula]

Hi Dave & Daniel -

Due to the separate feature pull we haven't picked up gem fixes until
now. Here's the first batch; there's potentially a few more to come [1].

I also just received a gvt fixes pull that didn't make it this week, so
there are still more fixes coming.

BR,
Jani.
