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 Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
