John Allen e70d59700f powerpc/pseries: Introduce memory hotplug READD operation ... Currently, memory must be hot removed and subsequently re-added in order to dynamically update the affinity of LMBs specified by a PRRN event. Earlier implementations of the PRRN event handler ran into issues in which the hot remove would occur successfully, but a hotplug event would be initiated from another source and grab the hotplug lock preventing the hot add from occurring. To prevent this situation, this patch introduces the notion of a hot "readd" action for memory which atomizes a hot remove and a hot add into a single, serialized operation on the hotplug queue.
