GHCB doc says:

"This document defines and owns reason code set 0x0"

Should it also say, reason code set 1 is allocated for Linux guest use?
I don't see why not...

If Tom is okay with it then maybe in next version of the GHCB doc can add
this text.

IIRC, during the review of the first GHCB version there was discussion
about assigning reason sets outside of 0 within the spec and the overall
feeling was to not do that as part of the spec.

We can re-open that discussion for the next version of the GHCB document.

Thanks,
Tom
