From: Arnd Bergmann <arnd@xxxxxxxx>
As I've queued up some patches for asm-generic, I remembered an
older series that I created but never submitted.
These two functions appear to be unnecessarily different between
architectures, and the asm-generic version is a bit questionable,
even for NOMMU architectures.
Clean this up to just use the generic library version for anything
that uses the generic version today. I've expanded on the patch
descriptions a little, as suggested by Christoph Hellwig, but I
suspect a more detailed review would uncover additional problems
with the custom versions that are getting removed.
