[PATCH v3 0/2] Shmem mTHP controls and stats improvements

[Ryan Roberts <ryan.roberts@arm.com>]

Hi All,

This is a small series to tidy up the way the shmem controls and stats are
exposed. These patches were previously part of the series at [2], but I decided
to split them out since they can go in independently.

---
This applies against today's mm-unstable (275d686abcb59). (although I had to fix
a minor build bug in stackdepot.c due to MIN() not being defined in this tree).
All mm selftests have been run; no regressions were observed.

Changes since v2 [2]
====================
  - swpout stats are now exposed for all orders supported by anon or shmem.

Thanks,
Ryan
