Pull ACPI and power management fixes from
 "These fix two bugs in the intel_pstate driver, a hibernate bug leading
  to nasty resume failures sometimes and acpi-cpufreq initialization bug
  that causes problems to happen during module unload when intel_pstate
  is in use.

  Specifics:

   - Fix for rounding errors in intel_pstate causing CPU utilization to
     be underestimated from Brennan Shacklett.

   - intel_pstate fix to always use the correct max pstate value when
     computing the min pstate from Dirk Brandewie.

   - Hibernation fix for deadlocking resume in cases when the probing of
     the device containing the image is deferred from Russ Dill.

   - acpi-cpufreq fix to prevent the module from staying in memory when
     the driver cannot be registered and then attempting to unregister
     things that have never been registered on exit"
