Merge branch 'drm-fixes' of git://people.freedesktop.org/~airlied/linux
Pull drm fixes from Dave Airlie:
"This is radeon and intel fixes, and is a small bit larger than I'm
guessing you'd like it to be.
- i915: fixes 32-bit highmem i915 blank screen, semaphore hang and
runtime pm fix
- radeon: gpuvm stability fix for hangs since 3.15, and hang/reboot
regression on TN/RL devices,
The only slightly controversial one is the change to use GB for the
vm_size, which I'm letting through as its a new interface we defined
in this merge window, and I'd prefer to have the released kernel have
the final interface rather than changing it later"
