Zi Yan 6d21130312 selftests/mm: skip guard_regions.uffd tests when uffd is not present
Patch series "Skip mm selftests instead when kernel features are not
present", v2.

Two guard_regions tests on userfaultfd fail when userfaultfd is not
present.  Skip them instead.

hugevm test reads kernel config to get page table level information and
fails when neither /proc/config.gz nor /boot/config-* is present.  Skip it
instead.


This patch (of 2):

When userfaultfd is not compiled into kernel, userfaultfd() returns -1,
causing guard_regions.uffd tests to fail.  Skip the tests instead.
