Merge branch 'drm-fixes' of git://people.freedesktop.org/~airlied/linux
Pull drm fix from Dave Airlie:
"Just a quick fix that a few people have reported, be nice to have in
asap"
The drm tree seems to be very confused about 64-bit divides. Here it
uses a slow 64-by-64 bit divide to divide by a small constant. Oh well.
Doesn't look performance-critical, just stupid.

drm/radeon: fix 64 bit divide in SI spm code
