There is currently no .s file for cpu() on non-x86 architechtures. Adding support for ARM should be fairly straightforward by reading the CPU ID register, but I don't have a machine to test this on. Patches are welcome.

A fallback mechanism should probably also be implemented to allow DRWMutex to use the SYS_GETCPU syscall (although it is slow) if need be. In that particular case, just returning 0 (and thus falling back to the behaviour of the regular sync.RWMutex) might be better.
