[Qemu-devel] [RESEND PATCH v4 0/6] QEMU memory hot unplug support

[Zhu Guihua <zhugh.fnst@cn.fujitsu.com>]

Memory hot unplug are both asynchronous procedures.
When the unplug operation happens, unplug request cb is called first.
And when guest OS finished handling unplug, unplug cb will be called
to do the real removal of device.

v4:
 -reorganize the patchset
 -drop the new API acpi_send_gpe_event()
 -update ssdt-mem

v3:
 -commit message changes
 -reorganize the patchset, squash and separate some patches
 -update specs about acpi_mem_hotplug
 -first cleanup external state, then un-map and un-register memory device

v2:
 -do a generic for acpi to send gpe event
 -unparent object by PC_MACHINE
 -update description in acpi_mem_hotplug.txt
 -combine the last two patches in the last version
 -cleanup external state in acpi_memory_unplug_cb
