I gues they were stuck because we didn't have someone who reported that it's fixed, plus they lacked an ack from Dave for the 2 core patches. tbh I'd just apply them all to drm-intel-fixes and then send out a pull for that (there's two more bugfix patches on it which missed Dave's main pull by a notch).
