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"
