[00/16] selftest/mm: Remove warnings found by adding compiler flags

Message

Recently, I reviewed a patch on the mm/kselftest mailing list about a
test which had obvious type mismatch fix in it. It was strange why that
wasn't caught during development and when patch was accepted. This led
me to discover that those extra compiler options to catch these warnings
aren't being used. When I added them, I found tens of warnings in just
mm suite.

In this series, I'm fixing those warnings. The last check adds the
compiler flags with which the warnings have been caught.
