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

Pull drm fixes from Dave Airlie:
 "For your Friday pull request stack, nothing astounding or shattering
  this week some exynos, some intel, some radeon fixes.  One intel fix
  for a regression somwehere back in 2.6.35 land."

* 'drm-fixes' of git://people.freedesktop.org/~airlied/linux:
  drm/radeon/kms: use frac fb div on APUs
  drm/radeon: add a missing entry to encoder_names
  drm/i915: handle input/output sdvo timings separately in mode_set
  drm/i915: fix integer overflow in i915_gem_do_execbuffer()
  drm/i915: fix integer overflow in i915_gem_execbuffer2()
  drm/exynos: added missed vm area region mapping type.
  drm/exynos: fixed exynos_drm_gem_map_pages bug.
  drm/exynos: fixed duplicatd memory allocation bug.
  drm/i915: fixup load-detect on enabled, but not active pipe
