 When an SEV-SNP issues a guest request for an attestation report, it has the
 option of issuing it in the form an *extended* guest request when a
 certificate blob is returned alongside the attestation report so the guest
 can validate the endorsement key used by SNP firmware to sign the report.
 These certificates are managed by userspace and are requested via
-KVM_EXIT_VMGEXITs using the KVM_USER_VMGEXIT_REQ_CERTS type.
