Merge tag 'v3.16-rc4' into drm-intel-next-queued
Due to Dave's vacation drm-next hasn't opened yet for 3.17 so I couldn't move my drm-intel-next queue forward yet like I usually do. Just pull in the latest upstream -rc to unblock patch merging - I don't want to needlessly rebase my current patch pile really and void all the testing we've done already.
