Previously, we have posted ~45+ patches for TDX guest support. But we have noticed that submitting too many TDX patches at the same time seems to complicates the review process.
So to make the review process simpler, we had planned to resubmit only a minimum set required to boot the TDX guest to user space (which comes around 25 patches).
Since moving HLT PV calls under CONFIG_PARAVIRT is an optimization fix we did not include it in the minimal set.
If you think otherwise, please let me know. We will drop the use of PARAVIRT_XXL and just use the above-mentioned patch.
