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.

Commit 916e3e5f ("KVM: SVM: Do not use user return MSR support for virtualized TSC_AUX") introduced a local variable used for the rdmsr() function for the high 32-bits of the MSR value. This variable is not used after being set and triggers a warning or error, when treating warnings as errors, when the unused-but-set-variable flag is set. Mark this variable as __maybe_unused to fix this.
