Dear drm-misc and drm-intel maintainers. Since the merge window has 
ended and the trees are fully open for the patches, I'd like to massage 
this patch series. We have R-B on all three patches. Heikki has acked 
the first patch, so it seems to be fine from the i915 point of view.

Is it fine to be merged via drm-misc? Would you like to pick it up into 
drm-intel?
