-          Allow a node to have only movable memory.  Pages used by the kernel,
-          such as direct mapping pages cannot be migrated.  So the corresponding
-          memory device cannot be hotplugged.  This option allows the following
-          two things:
-          - When the system is booting, node full of hotpluggable memory can
-          be arranged to have only movable memory so that the whole node can
-          be hot-removed. (need movable_node boot option specified).
-          - After the system is up, the option allows users to online all the
-          memory of a node as movable memory so that the whole node can be
-          hot-removed.
-
-          Users who don't use the memory hotplug feature are fine with this
-          option on since they don't specify movable_node boot option or they
-          don't online memory as movable.
-
-          Say Y here if you want to hotplug a whole node.
-          Say N here if you want kernel to use memory on all nodes evenly.
