I'm seeing regressions on multiple arm64 platforms in at least the LTP
clone302 and madvise10 selftests, both of which have bisected to one of
the fixups to this patch.  Especially given the other tests that also
bisected to the same place I've not investigated further.  There's a
number of other LTP tests that started failing today including relevant
seeming ones munlockall01, mprotect04, madvise10, mprotect03 and
futex_cmp_requeue01 but I don't have bisects to confirm they're the same
thing.

clone302:
