hrmpf, one of those wonderful messages where neither it nor its source

This has been an especially interesting year in the field. We've landed the
infrastructure for generic runtime power management, glued that into PCI
and started implementing that at the driver level. pm_qos is being reworked
to improve performance and scalability as we start seeing more drivers that
need to express their own constraints. And, of course, we had the
wakelock/suspend blockers conversation that didn't end in a terribly
satisfactory manner, although Rafael is now working on an implementation
that presents equivalent functionality with a different userspace API.
