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.
