Perhaps it's just because I'm coming in late, but I cannot understand why
NR_CPUS cannot be as low as 4 by default, for all archs, and then in the
kernel boot messages, should more be found than is configured for a message is
emitted to say "reconfigure your kernel", and continue with the number it was
configured for. I personally only rarely see 2-way boxes, 4-way is pretty
rare, and anything more must surely count as very specialized.

Let the defaults be reasonable for 99% of users (IMO 99.9%), and let the rest
have to think about config options...
