[ Upstream commit 767f4b620e ]
Hypervisors likely do not expose the SMCA feature to the guest and
loading this module leads to false warnings. This module should not be
loaded in guests to begin with, but people tend to do so, especially
when testing kernels in VMs. And then they complain about those false
warnings.
Do the practical thing and do not load this module when running as a
guest to avoid all that complaining.

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.
