When SEV-SNP is not supported, only two new MSR protocol VMGEXIT calls need to be supported: - MSR-based AP-reset-hold - MSR-based HV-feature-request These calls are implemented by here and then the protocol is lifted to version 2. This is submitted separately because the MSR-based AP-reset-hold call is required to support kexec/kdump in SEV-ES guests.
