Merge tag 'v3.12-rc2' into drm-intel-next

Backmerge Linux 3.12-rc2 to prep for a bunch of -next patches:
- Header cleanup in intel_drv.h, both changed in -fixes and my current
  -next pile.
- Cursor handling cleanup for -next which depends upon the cursor
  handling fix merged into -rc2.

All just trivial conflicts of the "changed adjacent lines" type:
	drivers/gpu/drm/i915/i915_gem.c
	drivers/gpu/drm/i915/intel_display.c
	drivers/gpu/drm/i915/intel_drv.h
