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.
