You must apply part1-3 before applying this patchset.

we need a node which only contains movable memory. This feature is very
important for node hotplug. If a node has normal/highmem, the memory
may be used by the kernel and can't be offlined. If the node only contains
movable memory, we can offline the memory and the node.

   numa: add CONFIG_MOVABLE_NODE for movable-dedicated node
   memory_hotplug: allow online/offline memory to result movable node
