This is the v5 of this series which tries to implement the fd-based KVM
guest private memory. The patches are based on latest kvm/queue branch
commit:

  d5089416b7fb KVM: x86: Introduce KVM_CAP_DISABLE_QUIRKS2

Can this series be run and a VM booted without TDX?  A feature like
that might help push it forward.
