Subject: [PATCH 0/3] KVM: VMX: Initialize TDX when loading KVM module

Hi Paolo/Sean,

This series contains patches to initialize TDX when loading KVM module.
This series is based on the discussion with Sean on the v19 patchset
[*], hoping it has addressed most (if not all) comments.

This series has been in our internal TDX tree for long time and has been
in kvm-coco-queue for some time thus it has been tested.

The main purpose for sending out is to have a review but this series can
also be applied to kvm/queue cleanly.

Thanks for your time!
