== SRU Justification ==
During testing, IBM found that cpupower idle-info is not listing stop4 and 
stop5 idle states when all CORES are guarded.  A patch has been
submitted upstream by IBM.  However, the patch has not landed in
linux-next or mainline as of yet.  For that reason, this SRU request is
being sent as a SAUCE patch request.


== Fix ==
UBUNTU: SAUCE: cpuidle/powernv : init all present cpus for deep states

== Regression Potential ==
Low.  Limited to powerpc.

== Test Case ==
A test kernel was built with this patch and tested by the original bug reporter.
The bug reporter states the test kernel resolved the bug.
