Subject: [PATCH v1 0/3] mm: minor cleanups around NUMA hinting

Working on some GUP cleanups (e.g., getting rid of some FOLL_ flags) and
preparing for other GUP changes (getting rid of FOLL_FORCE|FOLL_WRITE for
for taking a R/O longterm pin), this is something I can easily send out
independently.

Get rid of FOLL_NUMA, allow FOLL_FORCE access to PROT_NONE mapped pages
in GUP-fast, and fixup some documentation around NUMA hinting.
