Some time ago we discussed that using "id" as property name is not the right thing to do, as it is a reserved property for other devices and will not work with device_add. Switch to the term "core-id" instead, and use it as an equivalent to "CPU address" mentioned in the PoP. There is no such thing as cpu number, so rename env.cpu_num to env.core_id. We use "core-id" as this is the common term to use for device_add later on (x86 and ppc). We can get rid of cpu->id now. Keep cpu_index and env->core_id in sync. cpu_index was already implicitly used by e.g. cpu_exists(), so keeping both in sync seems to be the right thing to do. cpu_index will now no longer automatically get set via cpu_exec_realizefn(). For now, we were lucky that both implicitly stayed in sync. Our new cpu property "core-id" can be a static property. Range checks can be avoided by using the correct type and the "setting after realized" check is done implicitly. device_add will later need the reserved "id" property. Hotplugging a CPU on s390x will then be: "device_add host-s390-cpu,id=cpu2,core-id=2".
