Breno Leitao c8b9073142 selftests/mm: export get_free_hugepages()
Patch series "New selftest for mm", v2.

This is a simple test case that reproduces an mm problem[1], where a page
fault races with madvise(), and it is not trivial to reproduce and debug.

This test-case aims to avoid such race problems from happening again,
impacting workloads that leverages external allocators, such as tcmalloc,
jemalloc, etc.

This patch (of 2):

get_free_hugepages() is helpful for other hugepage tests.  Export it to
the common file (vm_util.c) to be reused.
