Clear the CR3 and INVLPG interception controls at runtime based on whether or not EPT is being _used_, as opposed to clearing the bits at setup if EPT is _supported_ in hardware, and then restoring them when EPT is not used. Not mucking with the base config will allow using the base config as the starting point for emulating the VMX capability MSRs.

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.
