Subject[v2.6.34-stable 097/165] xen/timer: Missing IRQF_NO_SUSPEND in timer code broke suspend.
Date
From: Ian Campbell <Ian.Campbell@citrix.com>

-------------------
This is a commit scheduled for the next v2.6.34 longterm release.
http://git.kernel.org/?p=linux/kernel/git/paulg/longterm-queue-2.6.34.git
If you see a problem with using this for longterm, please comment.
-------------------

commit f611f2da99420abc973c32cdbddbf5c365d0a20c upstream.

The patches missed an indirect use of IRQF_NO_SUSPEND pulled in via
IRQF_TIMER. The following patch fixes the issue.

With this fixlet PV guest migration works just fine. I also booted the
entire series as a dom0 kernel and it appeared fine.
