Subject: [GIT PULL] Power management changes for v4.18-rc2

Hi Linus,

Please pull from the tag

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 pm-4.18-rc2

with top-most commit b51e001385f1c861445af3efeab766811ee8db29

 Merge branch 'pm-tools'

on top of commit ce397d215ccd07b8ae3f71db689aedb85d56ab40

 Linux 4.18-rc1

to receive power management changes for 4.18-rc2.

These are mostly fixes, including some fixes for changes made
during the recent merge window and some "stable" material, plus
some minor extensions of the turbostat utility.

Specifics:

 - Fix the PM core to avoid introducing a runtime PM usage counter
   imbalance when adding device links during driver probe (Rafael
   Wysocki).

 - Fix the operating performance points (OPP) framework to ensure
   that the regulator voltage is always updated as appropriate when
   updating clock rates (Waldemar Rymarkiewicz).

 - Fix the intel_pstate driver to use correct max/min limits for
   cores with differing maximum frequences (Srinivas Pandruvada).

 - Fix a typo in the intel_pstate driver documentation (Rafael
   Wysocki).

 - Fix two issues with the recently added Kryo cpufreq driver (Ilia
   Lin).

 - Fix two recent regressions and some other minor issues in the
   turbostat utility and extend it to provide some more diagnostic
   information (Len Brown, Nathan Ciobanu).

Thanks!
