I read hotadd-reserve patches again.. Okay, please preallocate if you want. Problem I found is: 1) Goto's rebuild_zonelist patch will not work if CONFIG_MEMORY_HOTPLUG=n. rebuild zonelist is necessary when the system has just memory < 4G at boot, and hot add memory > 4G. because x86_64 has DMA32, ZONE_NORAML is not included into zonelist at boot time if system doesn't have memory >4G at boot. 2) zone and node's spanned_pages and present_pages are not incremented. you should do.
