This is a refresh of Binbin's patches with a change to the userspace API. I am consolidating everything into a single KVM_EXIT_TDX and adding to the contract that userspace is free to ignore it *except* for having to reenter the guest with KVM_RUN. If in the future this does not work, it should be possible to introduce an opt-in interface. Hopefully that will not be necessary.
