Lemme type the whole thing here again so that we have it all summed up
in one place - I think we all agree by now:

- confidential computing guest stuff: arch/x86/coco/{sev,tdx}
- generic host virtualization stuff: arch/x86/virt/
- coco host stuff: arch/x86/virt/vmx/{tdx,vmx}.c and arch/x86/virt/svm/sev*.c

New stuff goes to the new paths - i.e., TDX guest, host, etc - old stuff
- AMD SEV/SNP will get moved gradually so that development doesn't get
disrupted. Or we can do a flag day, right before -rc1 or so, and move it
all so in one go. We'll see.

Thx.
