Pull power management fixes from Rafael Wysocki:
 "These fix up the intel_pstate driver after recent changes to prevent
  it from printing pointless messages and update the turbostat utility
  (mostly fixes and new hardware support).

  Specifics:

   - Make intel_pstate only load on Intel processors and prevent it from
     printing pointless failure messages (Borislav Petkov).

   - Update the turbostat utility:
      * Assorted fixes (Ben Hutchings, Len Brown, Prarit Bhargava).
      * Support for AMD Fam 17h (Zen) RAPL and package power (Calvin
        Walton).
      * Support for Intel Icelake and for systems with more than one die
        per package (Len Brown).
      * Cleanups (Len Brown)"

* tag 'pm-5.1-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:
  cpufreq/intel_pstate: Load only on Intel hardware
  tools/power turbostat: update version number
