Tom Lendacky d36946679e KVM: SVM: Add support for SEV-ES GHCB MSR protocol function 0x004 
The GHCB specification defines a GHCB MSR protocol using the lower
12-bits of the GHCB MSR (in the hypervisor this corresponds to the
GHCB GPA field in the VMCB).

Function 0x004 is a request for CPUID information. Only a single CPUID
result register can be sent per invocation, so the protocol defines the
register that is requested. The GHCB MSR value is set to the CPUID
register value as per the specification via the VMCB GHCB GPA field.

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.
