Hi Paolo,

(Sorry I am replying using Outlook)

This series is for TDX guest, but not TDX host.

For TDX host kexec support I am working on a series to address.  It's in Intel internal review but I plan to send it out soon.

Things got a little bit late behind original schedule because currently I am in travel for Chinese New Year and sometimes not convenient to get access to Linux machine or even network.
