The first four patches are fixes for XSA-332. The avoid WARN splats
and a performance issue with interdomain events.

Patches 5 and 6 are some additions to event handling in order to add
some per pv-device statistics to sysfs and the ability to have a per
backend device spurious event delay control.

Patches 7 and 8 are minor fixes I had lying around.

Juergen Gross (8):
  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
  xen/netback: fix spurious event detection for common event case
  xen/events: link interdomain events to associated xenbus device
  xen/events: add per-xenbus device event statistics and settings
  xen/evtchn: use smp barriers for user event ring
  xen/evtchn: use READ/WRITE_ONCE() for accessing ring indices

I am going to pick up the last 3 patches since Ross appears to be having some issues with #2 (and 4 and 5 went in via netdev tree)
