  To: qemu-devel, mst; +Cc: Zhu Guihua

Add a new API named acpi_send_gpe_event() to send hotplug SCI.
This API can be used by pci, cpu and memory hotplug.

This patch is rebased on pci branch in mst's tree.
git://git.kernel.org/pub/scm/virt/kvm/mst/qemu.git

v3:
 -rebase on pci branch in mst's tree
 -use the new API for memory hot unplug

v2:
 -fix the coding style
