Pull power management fixes from Rafael Wysocki:
"These include a fix for a recent regression in the ACPI CPU
performance scaling code, a PCI device power management fix,
a system shutdown fix related to cpufreq, a removal of an ACPI
suspend-to-idle blacklist entry and a build warning fix.
Specifics:
- Fix possible NULL pointer dereference in the ACPI processor scaling
initialization code introduced by a recent cpufreq update (Rafael
Wysocki).
- Fix possible deadlock due to suspending cpufreq too late during
system shutdown (Rafael Wysocki).
- Make the PCI device system resume code path be more consistent with
its PM-runtime counterpart to fix an issue with missing delay on
transitions from D3cold to D0 during system resume from
suspend-to-idle on some systems (Rafael Wysocki).
- Drop Dell XPS13 9360 from the LPS0 Idle _DSM blacklist to make it
use suspend-to-idle by default (Mario Limonciello).
- Fix build warning in the core system suspend support code (Ben
Dooks)"

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
