The first patches are a bunch of cleanups. 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.
In contrast to v2, this series now also adds support for hotplugging CPUs
in random core-id order (last two patches). 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.
I am pretty sure now that this patch series won't grow even more :)
v2 -> v3:
* "exec,dump,i386,ppc,s390x: don't include exec/cpu-all.h explicitly"
- dropped removal of one unrelated include
* "s390x: move subsystem_reset() to s390-virtio-ccw.h"
- previously "s390x: move two function declarations to s390-virtio-ccw.h"
- as Thomas requested, s390_cpu_addr2state() will be later moved to cpu.c
* "s390x: move sclp_service_call() to sclp.h"
- previously "s390x: move sclp_service_call() to interrupt.c"
- only move the declaration and make it compile
* "s390x: allow only 1 CPU with TCG"
- switch to simple ifdef. Let's see what people think about this one :)
* "s390x: print CPU definitions in sorted order"
- fix host model getting reported as static :(
* "s390x: CPU hot unplug via device_del cannot work"
- use the term "currently" instead of "never"
* "s390x: implement query-hotpluggable-cpus"
- as requested by Thomas, moving s390_cpu_addr2state() to cpu.c
* added "s390x: generate sclp cpu information from possible_cpus"
* added "s390x: allow CPU hotplug in random core-id order"
