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

    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.
