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". So the last patches in this series differ
to v1. I tried to stick as much as possible to x86.
On s390x, only complete cores can be plugged. Cores have to be plugged in
the right order (core-id 0, 1, 2 ...). CPU hot unplug is not supported
by the architecture.
In addition, we now also print the CPU model list in sorted order and allow
only 1 CPU for TCG.
v1 -> v2:
- "exec,dump,i386,ppc,s390x: don't include exec/cpu-all.h explicitly"
-- added a few instances I missed
- "s390x: get rid of s390-virtio.c"
-- move everything in the first shot and clean the "cpu_states" stuff up
in later patches, when we have ms->possible_cpus.
- Added "target/s390x: move typedef of S390CPU to its definition"
- Added "s390x: move s390_virtio_hypercall() to s390-virtio-hcall.h"
- Added "s390x: move two function declarations to s390-virtio-ccw.h"
- Added "s390x: move sclp_service_call() to interrupt.c"
- "target/s390x: use program_interrupt() in per_check_exception()"
-- Add a comment describing my concern
- "s390x: allow only 1 CPU with TCG"
-- Add a #define to easily be able to change it (e.g. for development)
- Added "target/s390x: set cpu->id for linux user when realizing"
- "target/s390x: use "core-id" for cpu number/address/id handling"
-- I now use "core-id" as property name, because that will be used by
device_add
- "target/s390x: rename next_cpu_id to next_core_id"
-- Also change to the term "core_id"
- Added "s390x: print CPU definitions in sorted order"
- Added "s390x: allow cpu hotplug via device_add"
- Added "s390x: CPU hot unplug via device_del cannot work"
- Added "s390x: implement query-hotpluggable-cpu"
- Added "s390x: get rid of cpu_s390x_create()"
