[PATCH 00/12] A minor flurry of selftest/mm fixes

[John Hubbard <jhubbard@nvidia.com>]

It turned out that an even dozen patches were required in order to get the
selftests building cleanly, and all running, once again. I made it worse on
myself by insisting on using clang, which seems to uncover a few more warnings
than gcc these days.

So I still haven't gotten to my original goal of running a new HMM test that
Alistair handed me (it's not here yet), but at least this fixes everything I ran
into just now.

John Hubbard (12):
  selftests/mm: fix uffd-stress unused function warning
