[00/10] Various page->flags cleanups

Message

The first two patches are bug fixes, although I'm not sure that either
architecture will have noticed.  There aren't a lot of uses of page->flags
left!  The big build-up here is to reworking stable_page_flags(), which
will definitely be a user-visible change.  I think a welcome one, given
the special case we had to spread the Slab flag into all tail pages.
