+From: Jan Beulich <jbeulich@suse.com>
+Subject: x86: force EFLAGS.IF on when exiting to PV guests
+
+Guest kernels modifying instructions in the process of being emulated
+for another of their vCPU-s may effect EFLAGS.IF to be cleared upon
+next exiting to guest context, by converting the being emulated
+instruction to CLI (at the right point in time). Prevent any such bad
+effects by always forcing EFLAGS.IF on. And to cover hypothetical other
+similar issues, also force EFLAGS.{IOPL,NT,VM} to zero.
+
+This is XSA-202.
