Protection keys was merged in 4.8.  We can ignore any of the selftests
changes before that.

But, it looks like the 4.9 selftests are a bit behind mainline.
Probably because I didn't cc stable@ on f50b4878329a.  I don't have a
strong opinion as to how up-to-date we want to keep the -stable
selftests.  Shua, is there a usual way that folks do this?
