http://www.kernel.org/pub/linux/kernel/people/andrea/patches/v2.6/2.6.34-rc5/transparent_hugepage-21.gz

This adds full numa awareness to all hugepage allocations (page faults
and khugepaged), it adds a generic document, and it includes the v8
memory compaction. It still has to run with the 2.6.33 anon-vma code
to avoid crashes in split_huge_page and migrate.c invoked by
memory-compaction (see vma_adjust and expand_downwards discussed on
lkml even after the more recent fixes).

Please review especially the generic document. If you want a patchbomb
I'll send it privately.
