Subject: [PATCH 00/12] 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.

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
  selftests/mm: fix unused variable warning in hugetlb-madvise.c
  selftests/mm: fix unused variable warning in migration.c
  selftests/mm: fix a char* assignment in mlock2-tests.c
  selftests/mm: fix invocation of tests that are run via shell scripts
  selftests/mm: .gitignore: add mkdirty, va_high_addr_switch
  selftests/mm: set -Wno-format-security to avoid uffd build warnings
  selftests/mm: fix a "possibly uninitialized" warning in pkey-x86.h
  selftests/mm: move psize(), pshift() into vm_utils.c
  selftests/mm: move uffd* routines from vm_util.c to uffd-common.c
  selftests/mm: fix missing UFFDIO_CONTINUE_MODE_WP and similar build
    failures
  selftests/mm: fix uffd-unit-tests.c build failure due to missing
    MADV_COLLAPSE
