Ajay Kaher 9233b85afb x86/vmware: Parse MP tables for SEV-SNP enabled guests under VMware hypervisors 
[ Upstream commit a2ab25529b ]

Under VMware hypervisors, SEV-SNP enabled VMs are fundamentally able to boot
without UEFI, but this regressed a year ago due to:

  0f4a1e8098 ("x86/sev: Skip ROM range scans and validation for SEV-SNP guests")

In this case, mpparse_find_mptable() has to be called to parse MP
tables which contains the necessary boot information.

[ mingo: Updated the changelog. ]

Fixes: 0f4a1e8098 ("x86/sev: Skip ROM range scans and validation for SEV-SNP guests")

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.
