Patch 0 is supposed to be a summary of a patch set, and it doesn't have a place in the 'git' repo, though it will live on in the email archives. But the details are captured in the individual patch commit messages, particularly in Patch 7 for this series. Separately, I want to add Confidential VMs as a topic in the Hyper-V documentation under Documentation/virt/hyperv. I'll do that once our work related to confidential computing is relatively stable.
