Subject: [PATCH 0/5 v1] PM / Domains: Generic PM domains improvements

Hi,

For the last few days I've been working on modifications of the generic
PM domains code allowing .start_device()/.stop_device() and drivers'
.runtime_suspend()/.runtime_resume() callbacks to execute things like
pm_runtime_resume() for other devices in the same PM domain safely
without deadlocking (the original motivation was a console driver on
shmobile that pm_runtime_get_*()/pm_runtime_put_*() are called for from
the other devices' .runtime_suspend()/.runtime_resume() callbacks).

I think I solved that problem, but in the process I found a few places
where fixes and/on improvements were necessary.  The patches in this
series address those issues.  They are on top of the branch at:

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/suspend-2.6.git pm-domains

Patches [1-2/5] are regarded as 3.1 material, the others not necessarily,
but I'd like to push them for 3.1 too if there are no complaints.

Thanks,
Rafael
