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-fixes' of git://people.freedesktop.org/~airlied/linux: drm/radeon: fix 64 bit divide in SI spm code
