At least this resolution in linux-next was wrong. It would just keep
on doing a cache invalidate on the same one-page address range over
and over again.

I think I did it right, but obviously can't test (and am too lazy to
build-test too).

Of course, it won't actually matter unless you have large folio on
csky, which is probably hard to impossible to trigger in practice, but
I thought I'd mention it if for no other reason than Guo Ren to be
aware and at least test-build and maybe think about it.
