Subject: [GIT PULL] Power management material for v5.1-rc3

Hi Linus,

Please pull from the tag

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 pm-5.1-rc4

with top-most commit 58b0cf8e2418c05ed277c83b5529bd0568bfcc78

 Merge branch 'pm-tools'

on top of commit 79a3aaa7b82e3106be97842dedfd8429248896e6

 Linux 5.1-rc3

to receive power management material for 5.1-rc4.

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).

Thanks!
