I don't know exactly what the /policy/ is, but not wanting to rock the
boat, the first iterations of this series only added it to x86. But then
Arnd joined the thread and said I should add it to all of them all at
once and separate that out into this commit, so that's what we have
here. I think the idea is to keep syscall numbers synchronized these
days between archs if possible.
