Subject: [RFC v9 PATCH 06/21] memory-hotplug: export the function acpi_bus_remove()
From: Wen Congyang <wency@...fujitsu.com>
The function acpi_bus_remove() can remove a acpi device from acpi device.
When a acpi device is removed, we need to call this function to remove
the acpi device from acpi bus. So export this function.
