      [CPUFREQ] Fix some more CPU hotplug locking. · ddad65df

      Lukewarm IQ detected in hotplug locking
      BUG: warning at kernel/cpu.c:38/lock_cpu_hotplug()

      As there are other places that call cpufreq_update_policy without
      the hotplug lock, it seems better to keep the hotplug locking
      at the lower level for the time being until this is revamped.
