Cover letter [patch 00/36] Transparent Hugepage support #11

This is a port of the latest version of transparent hugepage to
git://zen-kernel.org/kernel/mmotm.git

The relevant changes are the addition of the page_anon_vma patch, the patch to adapt the rss accounting to -mm, and a one liner fix in the clear_copy_huge_page cleanup patch (that was crashing hugetlbfs).
