+          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
