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.
