Merge branch 'drm-fixes' of git://people.freedesktop.org/~airlied/linux

Pull radeon drm stuff from Dave Airlie:
 "Just some radeon fixes, one is for an oops where we run out of ioremap
  space on some big hardware systems in 32-bit mode, stuff doesn't work
  properly but at least the machine will boot.

  One regression fix, and two bugs, one hw, one blit code."

* 'drm-fixes' of git://people.freedesktop.org/~airlied/linux:
  drm/radeon/kms: fix hdmi duallink checks
  drm/radeon/kms: set SX_MISC in the r6xx blit code (v2)
  drm/radeon: deal with errors from framebuffer init path.
  drm/radeon: fix a semaphore deadlock on pre cayman asics
