-From: Felix Fietkau <nbd@nbd.name>
-Subject: MIPS: fix cache flushing for highmem pages
-
-Most cache flush ops were no-op for highmem pages. This led to nasty
-segfaults and (in the case of page_address(page) == NULL) kernel
-crashes.
-
-Fix this by always flushing highmem pages using kmap/kunmap_atomic
-around the actual cache flush. This might be a bit inefficient, but at
-least it's stable.
