BTW, can you point me to those patches? I think it would be nice if we
could eventually
converge parts of get_user()/put_user() implementation on something
that works for all
architectures, we do seem to rewrite these way too often. Ideally we'd
have something
in asm-generic that provides all the wrappers, and just requires an
architecture to
implement the inline asm helpers for each of the sizes.
