This function doesn't have to return anything, so we can define it as void.

we'll have to fix that if powerpc can have a single node system whose node

That is, boot the kernel with "numa=debug" in the kernel command line and
it will print out the cpu-to-node associativity during boot. That way you
can figure out what was the original associativity that was set. This will
confirm the theory that the hypervisor sent a red

So I think its best to keep it as it is.

Nothing will break, its just that the code size will be a tiny bit
lesser on UP configs, that's all :-) Anyway, I think removing the ifdef
improves the readability
