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
