Linus Torvalds 408323581b - Add support for running the kernel in a SEV-SNP guest, over a Secure
VM Service Module (SVSM).
 
    When running over a SVSM, different services can run at different
    protection levels, apart from the guest OS but still within the
    secure SNP environment.  They can provide services to the guest, like
    a vTPM, for example.
 
    This series adds the required facilities to interface with such a SVSM
    module.

Pull x86 SEV updates from Borislav Petkov:

 - Add support for running the kernel in a SEV-SNP guest, over a Secure
   VM Service Module (SVSM).

   When running over a SVSM, different services can run at different
   protection levels, apart from the guest OS but still within the
   secure SNP environment. They can provide services to the guest, like
   a vTPM, for example.

   This series adds the required facilities to interface with such a
   SVSM module.

[ And as always: "SEV" is AMD's "Secure Encrypted Virtualization".

  I can't be the only one who gets all the newer x86 TLA's confused,
  can I?
