[Qemu-devel] [RFC qom-cpu v2 0/8] i386: add cpu hot remove support

[Chen Fan <chen.fan.fnst@cn.fujitsu.com>]

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.
