Note that I was prompt to apply those patches because I want them to spend as much time as possible in linux-next so that we can detect and fix regressions before the merge window. So please test linux-next on your hardware. This being said, nothing is set in stone, and if the series appears to break existing setups and we can't fix the problems before -rc6, I'll drop it.
