Linus Torvalds 55db8eb456 - Do the proper memory conversion of guest memory in order to be able to kexec
kernels in SNP guests along with other adjustments and cleanups to that
   effect
 
 - Start converting and moving functionality from the sev-guest driver into
   core code with the purpose of supporting the secure TSC SNP feature where
   the hypervisor cannot influence the TSC exposed to the guest anymore
 
 - Add a "nosnp" cmdline option in order to be able to disable SNP support in
   the hypervisor and thus free-up resources which are not going to be used
 
 - Cleanups

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.
