Subject: [PATCH 0/7] xen/events: bug fixes and some diagnostic aids

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

Patches 4 and 5 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 6 and 7 are minor fixes I had lying around.

Juergen Gross (7):
  xen/events: reset affinity of 2-level event initially
  xen/events: don't unmask an event channel when an eoi is pending
  xen/events: fix lateeoi irq acknowledgement
  xen/events: link interdomain events to associated xenbus device
  xen/events: add per-xenbus device event statistics and settings
  xen/evtch: use smp barriers for user event ring
  xen/evtchn: read producer index only once
