3.12-stable review patch. If anyone has any objections, please let me know.
===============
This is a single hunk introduced later in the upstream commit
cb900f41215447433cbc456d1c4294e858a84d7c (mm, hugetlb: convert
hugetlbfs to use split pmd lock). We need page_hstate even for
!HUGETLB_PAGE case for the next patch (mm: thp: give transparent
hugepage code a separate copy_page).
