Maybe CONFIG_SMP is there as a kindness to kernel building robots :-)

Yes, you can build this for a UP kernel (I just did, and there were no build
errors). But why? Nobody is going to take their dual socket server with over
a hundred logical processors and run a UP kernel on it.

Probably ditto for 64BIT. I didn't try the build without that. But minimum
memory on these systems is larger than supported by 32-bit kernels.
