- Prevent the thermal core from failing the registration of a cooling
device if its .get_cur_state() reports an incorrect state to start
with which may happen for fans handled through firmware-supplied AML
in ACPI tables (Rafael Wysocki).
- Make the ACPI thermal zone driver initialize all trip points with
temperature of 0 centigrade and below as invalid because such trip
point temperatures do not make sense on systems with ACPI thermal
control and they cause performance regressions due to permanent
thermal mitigations to occur (Rafael Wysocki).
- Restore passive polling management in the Step-Wise thermal governor
that uses it to ensure that all cooling devices used for thermal
mitigation will go back to their initial states eventually (Rafael
Wysocki).

Pull thermal control fixes from Rafael Wysocki:
"These fix three issues introduced recently, two related to defects in
ACPI tables supplied by the platform firmware and one cause by a
thermal core change that went too far:
- Prevent the thermal core from failing the registration of a cooling
device if its .get_cur_state() reports an incorrect state to start
with which may happen for fans handled through firmware-supplied
AML in ACPI tables (Rafael Wysocki)
- Make the ACPI thermal zone driver initialize all trip points with
temperature of 0 centigrade and below as invalid because such trip
point temperatures do not make sense on systems with ACPI thermal
control and they cause performance regressions due to permanent
thermal mitigations to occur (Rafael Wysocki)
- Restore passive polling management in the Step-Wise thermal
governor that uses it to ensure that all cooling devices used for
thermal mitigation will go back to their initial states eventually
(Rafael Wysocki)"

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 reStructuredText 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.
