- Fix a crash that occurs when a kernel with 'nosmt' in the command
line is used to resume the system from hibernation (as the "restore"
kernel), because memory mapping differences between the restore and
image kernels cause SMT siblings to be woken up from idle states
and subsequently they try to fetch instructions from incorrect
memory locations (Jiri Kosina).
- Cause the new Performance and Energy Bias Hint (EPB) code to be
built only if CONFIG_PM is set, because that code is not really
necessary otherwise (Rafael Wysocki).
- Add kerneldoc comments to documents some helper functions related
to system-wide suspend to avoid possible confusion regarding their
purpose (Rafael Wysocki).

Pull power management fixes from Rafael Wysocki:
"These fix a crash during resume from hibernation introduced during the
4.19 cycle, cause the new Performance and Energy Bias Hint (EPB) code
to be built only if CONFIG_PM is set and add a few missing kerneldoc
comments.

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.
