Right, you asked already about putting this under arch/x86/virt/ but on
a second thought, this doesn't look like

"- generic host virtualization stuff: arch/x86/virt/"

to me:

https://lore.kernel.org/r/Yg5nh1RknPRwIrb8@zn.tnic

Rather, this looks like it wants to be under

 arch/x86/virt/vmx/tdx/

where we said that this should be the coco host code place.
