But it's not just parisc. It's six other architectures as well, some of which aren't even SMP. Does !SMP && NUMA make any kind of sense?
I think really, this is just a giant horrible misunderstanding on the part of the MM people. There's no reason why an ARM chip with 16MB of memory at 0 and 16MB of memory at 1GB should be saddled with all the NUMA gunk.
