Depends. Iirc, someone said they'd prefer for doing it in one patch
in some circumstances on some system call we added years ago. But otoh,
having the syscall wiring done separately makes it easy for arch
maintainers to ack only the wiring up part. Both ways are valid imho.
(cachestat() did it for x86 and then all the others separately. So
really it seems a bit all over the place depending on the scenario.)
