Hi,
This is version 4 of patch series that provides a framework to choose the
state a pseries CPU must be put to when it is offlined.

Version 2: http://lkml.org/lkml/2009/8/28/102
Version 1:
When a CPU is offlined on POWER currently, we call rtas_stop_self() and hand
the CPU back to the resource pool. This path is used for DLPAR which will
cause a change in the LPAR configuration which will be visible outside.
