Xen 3.1 through 4.x, when running 64-bit hosts on Intel CPUs, does not
clear the NT flag when using an IRET after a SYSENTER instruction, which
allows PV guest users to cause a denial of service (hypervisor crash) by
triggering a #GP fault, which is not properly handled by another IRET
instruction.
