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.
