Merge commit origin/master into drm-intel-next
Conflicts are getting out of hand, and now we have to shuffle even
more in -next which was also shuffled in -fixes (the call for
drm_mode_config_reset needs to move yet again).
So do a proper backmerge. I wanted to wait with this for the 3.13
relaese, but alas let's just do this now.
Conflicts:
drivers/gpu/drm/i915/i915_reg.h
drivers/gpu/drm/i915/intel_ddi.c
drivers/gpu/drm/i915/intel_display.c
drivers/gpu/drm/i915/intel_pm.c
Besides the conflict around the forcewake get/put (where we chaged the
called function in -fixes and added a new parameter in -next) code all
the current conflicts are of the adjacent lines changed type.
