[GIT PULL] OMAP3 PM: preformance enhancements

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.


The following changes since commit 9a17d88e0586bb7189655f8f99484a872a474626:

  Merge tag 'omap-devel-c-for-3.6' of git://git.kernel.org/pub/scm/linux/kernel/git/pjw/omap-pending into devel-pm (2012-06-25 07:41:17 -0700)

are available in the git repository at:
