It has the distinct advantage that it works > with today's VM. I'd be glad to make NUMA the default config. That allows us to completely get rid of zones. Just keep nodes around. Then we have a DMA node and a DMA32 node (working like a headless memory node) and a highmem node. This would simplify the VM. But please do not have multiple nodes and multiple zones. If we do not like the term nodes then lets call them zones and get rid of the nodes. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
