Explicitly set GDTR.base and IDTR.base to zero when intializing the VMCB.
Functionally this only affects INIT, as the bases are implicitly set to
zero on RESET by virtue of the VMCB being zero allocated.
Per AMD's APM, GDTR.base and IDTR.base are zeroed after RESET and INIT.

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.
