mm: page_remove_rmap comments on PageAnon
Add a comment to s390's page_test_dirty/page_clear_dirty/page_set_dirty dance in page_remove_rmap(): I was wrong to think the PageSwapCache test could be avoided, and would like a comment in there to remind me. And mention s390, to help us remember that this block is not really common. Also move down the "It would be tidy to reset PageAnon" comment: it does not belong to s390's block, and it would be unwise to reset PageAnon before we're done with testing it.
