Use a dummy unused vmexit reason to mark the 'VM exit' that is happening when kvm exits to handle SMM, which is not a real VM exit. This makes it a bit easier to read the KVM trace, and avoids other potential problems due to a stale vmexit reason in the vmcb. If SVM_EXIT_SW somehow reaches svm_invoke_exit_handler(), instead, svm_check_exit_valid() will return false and a WARN will be logged.

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.
