- This is the ACPI generic container driver which supports
- ACPI0004, PNP0A05 and PNP0A06 devices
+ This allows _physical_ insertion and removal of CPUs and memory.
+ This can be useful, for example, on NUMA machines that support
+ ACPI based physical hotplug of nodes, or non-NUMA machines that
+ support physical cpu/memory hot-plug.
+
+ If one selects "m", this driver can be loaded with
+ "modprobe acpi_container".
