Ok, this series looks much better. The new mm/filemap.c diff looks
much better with the lock_page_or_retry() helper function, and on the
whole I think I can Ack this (although obviously not actually apply it
- but please do get it into linux-next).

The do_page_fault() part of the patch still looks ugly, but I don't
see any obvious way to improve on it.
