[PULL] Self-tests updates for non-4k pages, for 4.7-rc3

[PULL] Self-tests updates for non-4k pages, for 4.7-rc3

[David Sterba]

Hi,

this patchset enhances the self-tests to work on non-4k architectures (ppc64,
arm64). The diffstat may appear big, but there are lots of call sites that just
get another parameter (nodesize), so we now also test all valid combinations of
pagesize and nodesize for a given arch.

The patchset is part of preparatory work of the subpage-blocksize patchset, and
it's updating only non-production code so it's IMO safe to merge in an rc. I
have tested it on x86_64 to verify that it does not break the default usecase.
