  cpufreq: powernv: Set the cpus to nominal frequency during reboot/kexec
  cpufreq: powernv: Set the pstate of the last hotplugged out cpu in policy->cpus to minimum
  cpufreq: Allow stop CPU callback to be used by all cpufreq drivers
  cpufreq: cpu0: Make allocate_resources() work for any CPU
  cpufreq: cpu0: try regulators with name "cpu-supply"
  cpufreq: cpu0: Move per-cluster initialization code to ->init()
  cpufreq: cpu0: use dev_{err|warn|dbg} instead of pr_{err|warn|debug}
  cpufreq: cpu0: print relevant error when we defer probe
  cpufreq: cpu0: don't validate clock on clk_put()
  cpufreq: cpu0: Update Module Author
  cpufreq: Add support for per-policy driver data
