spapr: fix cpu core hotunplug call flow

[Qemu-devel] [PATCH 0/3] spapr: fix cpu core hotunplug call flow

Posted by Igor Mammedov 7 years, 2 months ago

Make cpu core hotunplug use the same (expected)
unplug_request/unplug call flow like spapr memory unplug
and mem/cpu unplug on x86.

While doing it separate internal cpu core handling and
machine wiring code and move machine related callbacks
close to related machine code in spapr.c.

Series applies on top of tags/ppc-for-2.9-20170202 pull req.

repo for testing:
  git@github.com:imammedo/qemu.git spapr_cpu_unplug_cleanup
