Subject: [GIT PULL] Power management fix for v4.15-rc6

Hi Linus,

Please pull from the tag

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 pm-4.15-rc6

with top-most commit 466a2b42d67644447a1765276259a3ea5531ddff

 cpufreq: schedutil: Use idle_calls counter of the remote CPU

on top of commit

 Linux 4.15-rc5

to receive a power management fix for 4.15-rc6.

This fixes a schedutil cpufreq governor regression from the 4.14
cycle that may cause a CPU idleness check to return incorrect results
in some cases which leads to suboptimal decisions (Joel Fernandes).

Thanks!
