Merge branch 'drm-fixes' of git://people.freedesktop.org/~airlied/linux
Pull drm fixes from Dave Airlie:
"A bunch of fixes:
- vmware memory corruption
- ttm spinlock balance
- cirrus/mgag200 work in the presence of efifb
and finally Alex and Jerome managed to track down a magic set of bits
that on certain rv740 and evergreen cards allow the correct use of the
complete set of render backends, this makes the cards operate
correctly in a number of scenarios we had issues in before, it also
manages to boost speed on benchmarks my large amounts on these
specific gpus."
