Keep me posted. So far, I've only tested it with highmem. Your config will take some tweaking because vmalloc space fills up all of lowmem if you don't use it for ZONE_NORMAL at boot-time. I'll work on fixing that. But, you're almost certainly going to be stuck adding the new memory to highmem, no matter that it's really in the lower 1GB of physical memory. Otherwise, we're going to have to screw with vmalloc space. -- Dave -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
