Subject[PATCH v2 4/4] KVM: SVM: Increase supported GHCB protocol version
Date
From: Brijesh Singh <brijesh.singh@amd.com>

Now that KVM has basic support for version 2 of the GHCB specification,
bump the maximum supported protocol version. The SNP specific functions
are still missing, but those are only required when the Hypervisor
supports running SNP guests.
