I decided to go the extra mile and implement CPU hotplug via "device_add", as well as "query-hotpluggable-cpus". On s390x, only complete cores can be plugged. CPU hot unplug is currently not supported by the architecture. Support for hotplugging CPUs in random core-id order (last two patches) is added. We once hat a KVM bug preventing this, but the stable patch should now be included in relevant places - 152e9f65d66f ("KVM: s390: fix wrong lookup of VCPUs by array index"). Current tooling will plug them in sequential order anyway, so it should not hurt. v4 -> v5: * Only moving code around, no conceptual changes. * "s390x: allow only 1 CPU with TCG" - Drop the ifdef stuff again. * "s390x: implement query-hotpluggable-cpus" - Don't move s390_cpu_addr2state(), we can clean that up later. - Moved dropping "cpu_states" to next patch. - Drop s390_find_cpu_slot(). * "s390x: get rid of cpu_states and use possible_cpus instead" - Added as requested by Igor.
