    Pull power management updates from Rafael Wysocki:
     "These rework the collection of cpufreq statistics to allow it to take
      place if fast frequency switching is enabled in the governor, rework
      the frequency invariance handling in the cpufreq core and drivers, add
      new hardware support to a couple of cpufreq drivers, fix a number of
      assorted issues and clean up the code all over.
    
      Specifics:
    
       - Rework cpufreq statistics collection to allow it to take place when
         fast frequency switching is enabled in the governor (Viresh Kumar).
    
       - Make the cpufreq core set the frequency scale on behalf of the
         driver and update several cpufreq drivers accordingly (Ionela
         Voinescu, Valentin Schneider).
    
       - Add new hardware support to the STI and qcom cpufreq drivers and
         improve them (Alain Volmat, Manivannan Sadhasivam).
    
       - Fix multiple assorted issues in cpufreq drivers (Jon Hunter,
         Krzysztof Kozlowski, Matthias Kaehlcke, Pali Rohár, Stephan
         Gerhold, Viresh Kumar).
    
       - Fix several assorted issues in the operating performance points
         (OPP) framework (Stephan Gerhold, Viresh Kumar).
    
       - Allow devfreq drivers to fetch devfreq instances by DT enumeration
         instead of using explicit phandles and modify the devfreq core code
         to support driver-specific devfreq DT bindings (Leonard Crestez,
         Chanwoo Choi).
    
       - Improve initial hardware resetting in the tegra30 devfreq driver
         and clean up the tegra cpuidle driver (Dmitry Osipenko).
    
       - Update the cpuidle core to collect state entry rejection statistics
         and expose them via sysfs (Lina Iyer).
    
       - Improve the ACPI _CST code handling diagnostics (Chen Yu).
    
       - Update the PSCI cpuidle driver to allow the PM domain
         initialization to occur in the OSI mode as well as in the PC mode
         (Ulf Hansson).
    
       - Rework the generic power domains (genpd) core code to allow domain
         power off transition to be aborted in the absence of the "power
         off" domain callback (Ulf Hansson).
    
       - Fix two suspend-to-idle issues in the ACPI EC driver (Rafael
         Wysocki).
    
       - Fix the handling of timer_expires in the PM-runtime framework on
         32-bit systems and the handling of device links in it (Grygorii
         Strashko, Xiang Chen).
    
       - Add IO requests batching support to the hibernate image saving and
         reading code and drop a bogus get_gendisk() from there (Xiaoyi
         Chen, Christoph Hellwig).
    
       - Allow PCIe ports to be put into the D3cold power state if they are
         power-manageable via ACPI (Lukas Wunner).
    
       - Add missing header file include to a power capping driver (Pujin
         Shi).
    
       - Clean up the qcom-cpr AVS driver a bit (Liu Shixin).
    
       - Kevin Hilman steps down as designated reviwer of adaptive voltage
         scaling (AVS) drivers (Kevin Hilman)"
