Merge tag 'x86_sev_for_v7.2_rc1' of gitolite.kernel.org:pub/scm/linux/kernel/git/tip/tip
Pull x86 SEV updates from Borislav Petkov:
- Remove redundant GHCB initialization guards in the SEV page state and
SVSM call paths now that the GHCB helpers handle early-boot fallback
internally
- Skip SNP initialization in the CCP driver immediately when the
preparation step fails rather than proceeding to an operation that
will certainly fail
- Abort SNP preparation and return an error when not all CPUs are
online, since the firmware enforces that every CPU enables SNP and
will fail init if not
- Simplify the VMM communication exception entry path by replacing
separate kernel and user mode macros with a single handler that
dispatches based on the current privilege level
* tag 'x86_sev_for_v7.2_rc1' of gitolite.kernel.org:pub/scm/linux/kernel/git/tip/tip:
x86/sev: Remove redundant ghcbs_initialized checks around __sev_{get,put}_ghcb()
crypto/ccp: Skip SNP_INIT if preparation fails
x86/sev: Do not initialize SNP if missing CPUs
x86/entry: Zap the #VC entry user and kernel macros
