As specified in section 5.7.2 of the ACPI specification the feature
group string "3.0 _SCP Extensions" implies that the operating system
evaluates the _SCP control method with additional parameters.
However the ACPI thermal driver evaluates the _SCP control method
without those additional parameters, conflicting with the above
feature group string advertised to the firmware thru _OSI.
Stop advertising support for this feature string to avoid confusing
the ACPI firmware.

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.
