Subject: [GIT PULL] Power management fix for v4.17-rc4

Hi Linus,

Please pull from the tag

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 pm-4.17-rc4

with top-most commit d4f3388afd488ed15368fa7413b8bd6d1f98bb1d

 cpufreq / CPPC: Set platform specific transition_delay_us

on top of commit 6da6c0db5316275015e8cc2959f12a17584aeb64

 Linux v4.17-rc3

to receive a power management fix for 4.17-rc4.

This fixes a regression from the 4.14 cycle in the CPPC cpufreq
driver causing it to use an incorrect transition delay value
which leads to a very high rate of frequency change requests when
the schedutil governor is in use (Prashanth Prakash).

Thanks!
