Yup.  That looks good.  Means that my allnoconfig will now
have SMP=y though :-(  Root of that is selecting GENERIC,
and I'm not sure there is a better choice.

Doesn't change the need for the patch to delete the #if NUMA
clause inside the SMP=n path though (your patch would make my
build work by forcing SMP=y ... so the build error would go
away ... but that doesn't make it OK to have #if NUMA code
inside the SMP=n clause).

This does make we wonder how much dead code is hidden inside
impossibly nested #ifdefs elsewhere in the kernel.
