[Qemu-devel] [PATCH v3 03/10] acpi, mem-hotplug: Add acpi_send_gpe_event() to rise sci for memory hotplug.

[Zhu Guihua]

From: Tang Chen <address@hidden>

Add a new API named acpi_send_gpe_event() to send memory hotplug SCI.
Doing this is because this procedure will be used by other functions in the
next coming patches.
