If a CPU selected with the "cpu" command is hot-unplugged then "info cpus"
causes QEMU to exit:
(qemu) device_del cpu1
(qemu) info cpus
qemu:qemu_cpu_kick_thread: No such process
I could verify that this happens with x86 and ppc, but I guess s390x is
also impacted.
This series tries to fix the issue by using object_ref() and object_unref()
in the monitor code. For this to work on ppc, some preliminary work is
needed to let QOM handle the CPU object lifecycle.
Please comment.
