Hi John,

Here is another pull request for 3.15. I guess it will be the last one unless some issue arises.
I have a fix for a "merge damage" which is not really a merge damage: it enables scheduled scan which has been disabled in wireless.git. Since you merged wireless.git into wireless-next.git, this can now be fixed in wireless-next.git.

Besides this, Alex made a workaround for a hardware bug. This fix allows us to consume less power in S3. Arik and Eliad continue to work on D0i3 which is a run-time power saving feature. Eliad also contributes a few bits to the rate scaling logic to which Eyal adds his own contribution. Avri dives deep in the power code - newer firmware will allow to enable power save in newer scenarios. Johannes made a few clean-ups. I have the regular amount of BT Coex boring stuff. I disable uAPSD since we identified firmware bugs that cause packet loss. One thing that do stand out is the udev event that we now send when the FW asserts. I hope it will allow us to debug the FW more easily.

The udev thing will need tiny effort from distributions: to put the script and the udev rule (copied in the commit message) in place. Note that we have a debugfs hook to trigger a FW assert, so that it shouldn't really be an issue to put that in place and test that it actually works. The purpose of this is to have a file in /var/log (or wherever) with FW state / logs that we can give to the FW teams. I took the idea from the GPU folks who have a similar concept and Ubuntu even has a udev rule that dumps the error when something bad occurs (/sys/kernel/debug/dri/0/i915_error_state). I used debugfs, but I saw that Ubuntu ships with debugfs compiled and mounted (I hope this is the standard configuration). I haven't done an extensive research about other distros though...

Let me know if you have issues with this!
