Not directly.  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.
