Subject: [PATCH] selftests/mm: import strings.h for ffsl

Got a compilation error for ffsl after 91b80cc5b39f ("selftests: mm: fix
map_hugetlb failure on 64K page size systems") imported vm_util.h.

Fixes: af605d26a8f2 ("selftests/mm: merge util.h into vm_util.h")

Why do you think this Fixes tag is needed? This refers to a patch which is
just moving code. It doesn't seem to have any thing related to strings.h.

Other than that, LGTM

Oops, I guess it should be:

Fixes: 6f6a841fb77d ("selftest/vm: add helpers to detect PAGE_SIZE and
PAGE_SHIFT")
