Subject: "cpufreq: fix serialization issues with freq change notifiers" breaks
 cpufreq too

Sorry guys, I'm trying my best to stop this patch from propagating to 
stable and to get it fixed asap, so, the CC list might be a bit excessive. 
Also trying to fix the originally spare cc list, which makes it impossible 
for me to reply to the original thread, instead have to start a new one.

    cpufreq: fix serialization issues with freq change notifiers

breaks .transition_ongoing counting. This leads to cpufreq-cpu0 not 
working any more. In particular switching the governor from performance to 
powersave directly after boot doesn't result in a frequency switch any 
more. Reverting this patch fixes the problem again. Tested with today's 
-next.

Please, refrain from including into "stable" until clarified!

Thanks
Guennadi
