This driver supports ACPI memory hotplug. The driver
fields notifications on ACPI memory devices (PNP0C80),
which represent memory ranges that may be onlined or
offlined during runtime.

If your hardware and firmware do not support adding or
removing memory devices at runtime, you need not enable
this driver.
