Effectively reset supported_mce_cap on vendor module load to ensure that
capabilities aren't unintentionally preserved across module reload, e.g.
if kvm-intel.ko added a module param to control LMCE support, or if
someone somehow managed to load a vendor module that doesn't support LMCE
after loading and unloading kvm-intel.ko.
Practically speaking, this bug is a non-issue as kvm-intel.ko doesn't have
a module param for LMCE, and there is no system in the world that supports
both kvm-intel.ko and kvm-amd.ko.

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.
