I agree that it is very unlikely to find a single-processor NUMA

non-smp" adds _some_ extra complexity. But because SMP is set when
supporting more than one cpu, and NUMA is set when supporting more
than one memory node, I see no reason why they should be dependent on
each other. Except that they depend on each other today and breaking
them loose will increase complexity a bit.
hmm, observation from the peanut gallery, would it make sene to look at
useing the NUMA code on single proc machines that use PAE to access
more then 4G or ram on a 32 bit system?
2 problems:
1) there aren't any ;-)
2) The memory is not physically differently separated from the CPUs, so
it's not NUMA.
even though it's not physically differently seperated from the CPU(s)
doesn't it's differing performance amount to the same thing?
