I had a shot at integrating all this onto the pending stuff in linux-next. "mm: Add and use update_mmu_cache_pmd() in transparent huge page code." needed minor massaging in huge_memory.c. But as Andrea mentioned, we ran aground on Gerald's http://ozlabs.org/~akpm/mmotm/broken-out/thp-remove-assumptions-on-pgtable_t-type.patch, part of the thp-for-s390 work.
While working on a rebase relative to this work, I noticed that the s390 patches don't even compile. It's because of that pmd_pgprot() change from Peter Z. which arrives asynchonously via the linux-next tree. It makes THP start using pmd_pgprot() (a new interface) which the s390 patches don't provide. It's going to require that I do new work for my sparc64 THP changes as well.
