Hmm actually I haven't tested it but in theory the reserve hotplug code should just work if you list the new nodes already in SRAT as empty hotplug PXMs. Ok there is no code yet to add hotplug cpus to specific nodes later but that would be easy to add. The only problem is that mem_map has to be in another node so it will be slightly slower. -Andi - To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
