0 was a typo, i meant 1 for UP of course. 0 would be nonsensical.
Sure, I realised that. For a UP kernel, the test will compile away.
But Daniel seems to say there is dead code that could be compiled
out for SMP kernels. I just don't think that is possible because the
SMP kernel can boot a UP system where num_possible_cpus() is 1.
