[PATCH v6 08/10] kernel,cpuset: Use node-notifier instead of memory-notifier

[Oscar Salvador <osalvador@suse.de>]

cpuset is only concerned when a numa node changes its memory state,
as it needs to know the current numa nodes with memory to keep
an updated mems_allowed mask.
So stop using the memory notifier and use the new numa node notifer
instead.
