yes, that makes a lot of sense to me. If we introduce a new
asm-generic/unistd.h, it's good to have it sorted in some
meaningful way, even if it is going to get messier over time.

ok, I'll look at it tomorrow.

I guess I wasn't entirely clear with what I mean referring to
__ARCH_WANT_SYS_*. Instead of adding the #ifdef here, I meant
you should just remove the call entirely. With a few exceptions
that I already mentioned, the fact that there is an __ARCH_WANT
check in the syscall definition means that new architectures
should not reference the call, nor #define the __ARCH_WANT macro.
