This includes the MMU parts of "TDX/SNP part 1 of n"[1] while the rest was posted as "KVM: guest_memfd: New hooks and functionality for SEV-SNP and TDX"[2] last week. It includes two basic parts: - Allow non-zero value for non-present SPTE and removed SPTE, so that TDX can set the "suppress VE" bit - Use PFERR_GUEST_ENC_MASK to indicate fault is private. The changes from the previous posting were suggested by Chao Gao: - small adjustment to comments - fix checks for "!pte_access && !shadow_present_mask", rewriting them as "(pte_access | shadow_present_mask) != SHADOW_NONPRESENT_VALUE". - move allocation of ve_info outside init_vmcs() I'll push this series later this week to kvm/next, and rebase kvm-coco-queue on top.
