Tony,

Please pull the following PM/performance enhancements for v3.6.  I
recently rebased it on your devel-pm branch to avoid some conflicts
with the IO chain stuff recently merged from Paul.

This series had the goal of improving the responsiveness of the
shallowest idle states.  Several reports came in that even when only
hitting the shallowest idle states, there was a significant performance
hit.  This series addresses the major sources of latency in the
shallowest idle states.

Kevin

OK, pulling into devel-pm.
