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

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.

  selftests/mm: cow: remove unused variables and fix type mismatch
    errors
  selftests/mm: hmm-tests: Remove always false expressions
  selftests/mm: guard-pages: Fix type mismatch warnings
  selftests/mm: hugetlb-madvise: fix type mismatch issues
