The patches have received some more testing since the were first posted and
I've added a PM domains patch on top of them:

[3/3] - Make generic PM domains use the new device suspend/resume phases.

The series applies on top of linux-pm/pm-for-linus (although it should
apply on top of the current mainline too).

I'm considering these patches as v3.4 material, if there are no objections.

Thanks,
Rafael
