Subject: [PATCH] fixup! mm, fs: reduce fault, page_mkwrite, and pfn_mkwrite to take only vmf

I ran into a couple of build problems on ARM, these are the changes that
should be folded into the original patch that changed all the ->fault()
prototypes

Fixes: mmtom ("mm, fs: reduce fault, page_mkwrite, and pfn_mkwrite to take only vmf")
