Should I be seeing this "SMP alternatives" thing on a !CONFIG_SMP

The UP kernel has empty alternatives tables (as you've noticed), thus
the code doesn't do anything.  Nevertheless it probably makes sense to
add a few #ifdef CONFIG_SMP lines to avoid confusing people and safe a
few bytes ...

Okay, thanks. Yes, I agree such would make sense.
