That patch is insufficient: Xen guests still fail to initialize espfix64 correctly on SMP. It's currently unclear that espfix64 can work at all on Xen -- it's may be rather fundamentally incompatible with the Xen hypercall IRET mechanism. So it might need to be disabled entirely on Xen (and maybe Xen will fix the info leak in the hypervisor). > > This means that Linus's tree is also broken?
