Btw, why isn't the code in __page_set_anon_rmap() also doing this
cleaner version (ie a single "if (PageAnon(page)) return;" up front)?

The comments in that function are also some alien language translated
to english by some broken automatic translation service. Could
somebody clean up that function and come up with a comment that
actually parses as English and makes sense?
