[Qemu-ppc] [for-2.7 PATCH v3 00/15] Core based CPU hotplug for PowerPC sPAPR

[Bharata B Rao]

Hi,

This is v3 of "Core based CPU hotplug for PowerPC sPAPR". The hotplug
semantics looks like this:

(qemu) device_add POWER8E-spapr-cpu-core,id=core2,core=16[,threads=4]
(qemu) device_add POWER8E_v2.1-spapr-cpu-core,id=core2,core=16[,threads=4]

Changes in v3
-------------
- Moved CPU ObjectClass pointer from sPAPR specific CPU core type to
  its parent type, the abstract sPAPR CPU core type. This largely reduces
  the use of macros.
- Including Igor's QMP query-hotpluggable-cpus patches in this series.
- Added HMP version for query-hotpluggable-cpus.
- Added a patch to prevent QEMU crash due to DRC detach racing against attach.
- Addressed miscellaneous review comments from previous post.

v2.1: https://lists.gnu.org/archive/html/qemu-ppc/2016-03/msg00649.html
