Pull power management fixes from Rafael Wysocki:
 "These fix issues related to cpufreq, in the ACPI CPPC library and the
  generic CPPC cpufreq driver, in the powernow-k8 and amd-pstate
  drivers, and in the schedutil governor:

   - Allow fast frequency switching in the ACPI CPPC library only when
     every supported control used by the driver callback has an address
     space already accepted for fast access (Christian Loehle)

   - Skip writes to unsupported performance controls in the ACPI CPPC
     library (Christian Loehle)

   - Update cppc_cpufreq_update_perf_limits() to read policy->min and
     policy->max once and, if the lockless snapshot is inconsistent,
     reduce the minimum to the observed maximum, along the lines of
     cpufreq_driver_resolve_freq() (Christian Loehle)

   - Fix a possible memory leak in the powernowk8_cpu_init() error paths
     (Abdun Nihaal)

   - Loosen the requirement on lowest nonlinear frequency != min freq in
     the amd-pstate driver that is too tight for new systems some of
     which actually have the lowest nonlinear frequency identical to the
     minimum frequency (Mario Limonciello)

   - Prevent amd-pstate from loading on unsupported hardware (Rong
     Zhang)

   - Address an initialization race in the schedutil governor when it
     runs on multi-CPU cpufreq policies, by making it initialize all
     per-CPU structures first and only then publish the per-CPU
     utilization update hooks (Zhongqiu Han)"
