Worse name? Any name? If we come up with some name, "nmi" will still do
"restart" on s390, won't it (backward compatibility blablabla)? So there is
no point adding it for anyone but PPC64 and therefore it can be something
like "machinecheck" and we'll have yet another #ifdef in cpus.c. Which
would be very unusual and very awesome as I am normally not allowed to do
ppc-hacks in generic code :-D
