Merge tag 'x86_sev_for_v6.13' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

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

 - 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

[ Reminding myself about the endless TLA's again: SEV is the AMD Secure
  Encrypted Virtualization    - Linus ]
