Yes. It's an important property of Linux that it provides a common, portable API for all arch's, except where the obvious semantics (not performance) of a call are necessarily arch-specific.
Just coding up system calls for those arch's that happen to run a particular call super-fast, even though the call makes logical sense on all arch's, would lead to API chaos and impede application portability.
