[PATCH v3 00/11] A minor flurry of selftest/mm fixes

[John Hubbard]

Hi,

Changes since v2 [1]:

* Added a new patch (sent separately earlier) at the end, to error out
  if "make headers" has not yet been run.

* Reworked and simplified the uffd movement patch. Now it only moves
  some uffd*() routines, not all, and doesn't have to touch the Makefile
  at all. This lighter touch also allowed me to drop the "move psize(),
  pshift() into vm_utils.c" entirely. I expect Peter Xu will be a little
  happier with this new approach.

* Fixed the commit description for the MADV_COLLAPSE patch.

* Added more Reviewed-by tags from David Hildenbrand and Peter Xu.
