Merge tag 'x86_sev_for_v6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull x86 SEV updates from Borislav Petkov:

 - Some SEV and CC platform helpers cleanup and simplifications now that
   the usage patterns are becoming apparent

[ I'm sure I'm the only one that has gets confused by all the TLAs, but
  in case there are others: here SEV is AMD's "Secure Encrypted
  Virtualization" and CC is generic "Confidential Computing".

  There's also Intel SGX (Software Guard Extensions) and TDX (Trust
  Domain Extensions), along with all the vendor memory encryption
  extensions (SME, TSME, TME, and WTF).

  And then we have arm64 with RMA and CCA, and I probably forgot another
  dozen or so related acronyms    - Linus ]
