Patch series "A minor flurry of selftest/mm fixes".

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.


This patch (of 12):

uffd_minor_feature() was unused.  Remove it in order to fix the associated
clang build warning.
