mm: page fault scalability

Here comes the third batch of my page fault scalability patches, against
2.6.14-rc4-mm1.  This batch actually gets there.  There will be a little
more to come later (e.g. comments in ppc64, page_table_lock in sparc64,
perhaps out-of-lining pte_offset_map_lock - I haven't quite decided, and
attempt to update Documentation/vm/locking); but this is the most of it.
