Hi Linus,

Please pull from the tag

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
pm-4.18-rc6

with top-most commit 95d6c0857e54b788982746071130d822a795026b

cpufreq: intel_pstate: Register when ACPI PCCH is present

on top of commit 9d3cce1e8b8561fed5f383d22a4d6949db4eadbe

Linux 4.18-rc5

to receive a power management fix for 4.18-rc6.

This fixes a relatively old initialization issue in intel_pstate
causing the pcc-cpufreq driver to be used instead of it on some HP
Proliant systems, which turned into a functional regression during
the 4.17 cycle, because pcc-cpufreq is a scalability disaster and
that was amplified by the idle loop rework done at that time (Rafael
Wysocki).

Thanks!
