Those are fixes for XSA-332.

The rest of the V3 patches have been applied already. There is one
additional fix in patch 2 which addresses network outages when a guest
is doing reboot loops.

Juergen Gross (3):
  xen/events: reset affinity of 2-level event when tearing it down
  xen/events: don't unmask an event channel when an eoi is pending
  xen/events: avoid handling the same event on two cpus at the same time
