Date: Tue Oct 25 2011 - 09:16:55 EST
Hi Linus,
Please pull power management updates for 3.2 (on top of commit
3ee72ca99288f1de95ec9c570e43f531c8799f06) from:
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git pm-for-linus
with top-most commit 0ab1e79b825a5cd8aeb3b34d89c9a89dea900056
"PM / Clocks: Remove redundant NULL checks before kfree()".
They include:
* Runtime PM tracepoints (replacing not very useful debug printks) and fixes
from Ming Lei.
* Introduction of devfreq by MyungJoo Ham (special thanks to Mike Turquette
for reviewing all of the versions of this patchset).
* Introduction of device PM QoS from Jean Pihet.
* Generic PM domains core code refinements and extensions.
* SH7372 power management changes from Magnus Damm.
* Threaded hibernate image saving from Bojan Smojver.
* New entries for the ACPI suspend blacklist.
* Assorted fixes.
Thanks!
