Subject: [PATCH v3 0/3] KVM: VMX: Initialize TDX during KVM module load

This is a slightly reviewed version of Kai's same-titled series.
The changes in patch 4 I include rewording the comments, adding
a check that enable_virt_at_load=1, and an error message for
!cpu_feature_enabled(X86_FEATURE_TDX_HOST_PLATFORM).
