+          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 users to
+          online all the memory of a node as movable memory so that the whole
+          node can be hotplugged.  Users who don't use the memory hotplug
+          feature are fine with this option on since they don't online memory
+          as movable.

+          Say N here if you want kernel to use memory on all nodes evenly.
