Let the guest use 1g hugepages if TDP is enabled and the host supports GBPAGES, KVM can't actively prevent the guest from using 1g pages in this case since they can't be disabled in the hardware page walker. While injecting a page fault if a bogus 1g page is encountered during a software page walk is perfectly reasonable since KVM is simply honoring userspace's vCPU model, doing so arguably doesn't provide any meaningful value, and at worst will be horribly confusing as the guest will see inconsistent behavior and seemingly spurious page faults.
