sh: remove use of PG_arch_1 on individual pages
Patch series "Various page->flags cleanups".
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.
This patch (of 10):
Since switching to the new page table range API, we do not set the
PG_arch_1 (aka dcache clean) flag on tail pages, only on the folio. Test
it on the folio. Also use page_mapped() instead of page_mapcount() as it
is more efficient.
