[PATCH] Fix missing pfn variables caused by vm changes
I image this showed up because of "unused var..." when the changes occured, because flush_cache_page() is a noop in most places. This showed up for me on parisc however, where flush_cache_page() is a real function. Signed-off-by: Linus Torvalds <torvalds@osdl.org>
