Merge git://git.kernel.org/pub/scm/linux/kernel/git/davej/cpufreq
* git://git.kernel.org/pub/scm/linux/kernel/git/davej/cpufreq:
[CPUFREQ] state info wrong after resume
[CPUFREQ] allow use of the powersave governor as the default one
[CPUFREQ] document the currently undocumented parts of the sysfs interface
[CPUFREQ] expose cpufreq coordination requirements regardless of coordination mechanism
