You must apply part1-3 before applying this patchset.
Note: part1-3 are in mm tree now. part5 are being reimplemented(We will post it some days later). part6 is still in discussion.
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.
Changes from v1 to v2: 1. Add Tested-by: Yasuaki Ishimatsu <isimatu.yasuaki@jp.fujitsu.com> 2. Add my Signed-off-by, because I am on the the patch delivery path.
Lai Jiangshan (2): numa: add CONFIG_MOVABLE_NODE for movable-dedicated node memory_hotplug: allow online/offline memory to result movable node
