Thanks for cc'ing me on the patch. It conflicts with a couple of patches
I have in flight. I am happy to rebase on top if this one is ready for
merging.

One of the patches in the series, moves check_hugepage() from
hugetlb/lib/hugetlb.c into lib/mem.c[0] so that the hugepage check can
be added to thp tests.

Thanks,
Punit
