We have that - it's what the generic arch is. It's also good for distros, as it'll enable them to build one binary kernel and run it on flat SMP boxes and the Summit/x440 boxes. If we really want to do good testing, we should make a fake NUMA config that can run a 4x SMP box as fake NUMA, with half the memory in each "node" and half the processors ... but I never got around to coding that ;-) M. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
