Do the generic hugetlbfs code provides such an API ? If not, we may need
to add one.
I think it's something like

	huge_page_size(page_hstate(page))
That would work if you have a page, yes. If you want to query which hugepage
sizes are available, then you probably want for_each_hstate() (which is only
within mm/hugetlb.c at the moment, but I have no objections to exporting it
and symbols it requires).
