Unfortunately, some errors in the previous patch set break things in some of the DLPAR operations. In particular when attempting to hot-add a new CPU or set of CPUs, the original patch failed to properly calculate the available resources, and aborted the operation. In addition, the original set missed several opportunities to compress and reuse common code, especially, in the area of device processing. Signed-off-by: Michael W. Bringmann
