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

Pull x86 SEV updates from Borislav Petkov:

 - 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

  Encrypted Virtualization    - Linus ]
