That's a bad idea, given that we are about to make the CPU a device. So yes, there are devices that are not meant to be instantiated more than once (e.g., sclp-console). And there are devices that are not meant to be instantiated by the user at all. BTW this patch exposed that there is silly code in this function: When the bus is NULL, it is initialized as the SysBus. But we all know that SysBus is not hotplug-capable in the first place, so we can never device_add on SysBus.
