From: Arnd Bergmann <arnd@xxxxxxxx>
As I've queued up some patches for include/asm-generic/unistd.h, 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.
