Linus Torvalds 14bed9bc81 - Map the SNP calling area pages too so that OVMF EFI fw can issue SVSM
calls properly with the goal of implementing EFI variable store in the
   SVSM - a component which is trusted by the guest, vs in the firmware, which
   is not
 
 - Allow the kernel to handle #VC exceptions from EFI runtime services
   properly when running as a SNP guest
 
 - Rework and cleanup the SNP guest request issue glue code a bit

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.
