Via implementing ACPI standard methods _EJ0 in bios, after Guest OS hot remove
one vCPU, it is able to send a signal to QEMU, then QEMU could notify
the assigned vCPU of exiting.
this work is based on Andreas Färber's qom-cpu branch tree.

this series patches must be used with seabios patch and KVM patch together.

Chen Fan (8):
apic: remove apic_no from apic_init_common()
x86: add x86_cpu_unrealizefn() for cpu apic remove
qmp: add 'cpu-del' command support
qom cpu: rename variable 'cpu_added_notifier' to
'cpu_hotplug_notifier'
qom cpu: add UNPLUG cpu notifier support
i386: implement pc interface pc_hot_del_cpu()
