I am a little confused here.
I have configured Dom0 to be a uniprocessor kernel. Shouldn't that stop
SMP specific code from being executed?

No, X86_FIND_SMP_CONFIG defaults to y.

Won't setting num_processors=1 cause Dom0 to always be uniproc even if
SMP is turned on?

Xen0-smp doesn't need to look at the MP table to figure out how many virtual processors there are. There are other mechanisms to discover virtual processors.

The MP table is needed mostly to setup the IOAPICs and the interrupt routing.
