I folded the page_anon_vma patch into transparent_hugepage. It was however good idea to keep it separated first time around IMHO to make reviewing of the changes feasible (it's still there to review on the list in the #11 submit if others wants to review). Let me know if something else is needed to merge into -mm. After that we can start to call memory compaction in alloc_hugepage(int defrag) if defrag == 1. Thanks!
