For us on IA64 a zone describes the memory of a node in a NUMA system. This is due to our IA64 not having memory issues like restricted DMA areas or not directly addressable memory. That memory is to be used in the same manner. Yes. So in principle this would also work for us. I'd like to have an option though to get rid of all the extra zones if one has a clean memory architecture. We still carry the DMA and HIGHMEM stuff around without purpose. Would this also mean that one can dynamically add/remove memory to a zone if the memory has to be treated the same way? -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
