Merge tag 'v3.9-rc5' into drm-intel-next-queued
Backmerge Linux 3.9-rc5 since I want to merge a few dp clock cleanups
for -next, but they will conflict all over the place with
commit 9d1a455b0ca1c2c956b4d9ab212864a8695270f1
Author: Takashi Iwai <tiwai@suse.de>

drm/i915: Use the fixed pixel clock for eDP in intel_dp_set_m_n()
from -fixes.
Conflicts:
drivers/gpu/drm/i915/intel_dp.c: Simply adjacent lines changed.
drivers/gpu/drm/i915/intel_panel.c: A field rename in -next
conflicts with a bugfix in -fixes. Take the version from
-fixes and apply the rename.
