Subjectlongterm backport request: xen/timer: Missing IRQF_NO_SUSPEND in timer code broke suspend
From
Date
(resending since I suspect stable@ was down the first time round. Also I
should have CC'd Thomas & LKML, I think)

Hi Greg,

Please can you queue this commit for 3.6.32.y

commit f611f2da99420abc973c32cdbddbf5c365d0a20c
Author: Ian Campbell <Ian.Campbell@citrix.com>
Date: Tue Feb 8 14:03:31 2011 +0000

xen/timer: Missing IRQF_NO_SUSPEND in timer code broke suspend.

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.

It is needed in any tree which contains 676dc3cf5bc3 "xen: Use
IRQF_FORCE_RESUME" but not this change (everything was fixed upstream in
2.6.39-rc1).

It's a bit hard to tell in the absence of kernel.org but I have an old
(but post February) checkout of the 2.6.35 longterm and it does not appear
to have the original problematic patch so the fix isn't needed there.
IOW AFAICT right now 2.6.32 seems to be the only relevant tree.

Thanks,
Ian.
