#     Pull xen fix from Juergen Gross:
#      "A fix for the xen events driver:
#     
#       Closing of an event channel in the Linux kernel can result in a
#       deadlock. This happens when the close is being performed in parallel
#       to an unrelated Xen console action and the handling of a Xen console
#       interrupt in an unprivileged guest.
#     
#       The closing of an event channel is e.g. triggered by removal of a
#       paravirtual device on the other side. As this action will cause
#       console messages to be issued on the other side quite often, the
#       chance of triggering the deadlock is not negligible"
