While not complete, Ilyas patch clearly improves the situation (and it is pretty similar to the EDAT-1 support). I think the question is: are there other instruction that we emulate in qemu via the page table walker even for KVM? I believe we always go via the kvm memory ioctl for page table access via instructions so the patch is not critical for KVM. So unless we have something I think Connys proposal is reasonable.
