Cover letter [0/3, v4] CPU Hotplug Emulatation

According to the discussion result on NUMA Hotplug Emulator. There are many suggestions on node/Memory hotplug emulation, and David Rientjes provides a more flexiable solution for node/memory hotplug. We appreciate for his patches, and we accept his numa=possible=<N> parameters.

For CPU hotplug emulatinon, there are no opposite voices from the community, and think CPU probe/release is an useful interface. There is no obvious relationship with node/memory hotplug, it can work well alone, so I send CPU hotplug emulation patcheset standalone. it makes the patch reviewing process faster.
