Attached is an updated draft version of the SVSM specification with 
feedback incorporated from the previous review.

Also attached is a draft GHCB specification with updates for APIC ID 
retrieval and VMPL/VMSA level execution (and an SEV-ES enhancement to use 
the SNP Page State Change support for working with UPM).

Please take a look and reply with any feedback you may have.

Thanks,
Tom
