[PATCH v2 0/2] Skip mm selftests instead when kernel features are not present

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.

Zi Yan (2): selftests/mm: skip guard_regions.uffd tests when uffd is not present. selftests/mm: skip hugevm test if kernel config file is not present.
