Date: Wed, 02 Nov 2011 15:14:57 -0700 From: Greg KH <gregkh@...e.de> To: linux-kernel@...r.kernel.org, stable@...r.kernel.org Cc: torvalds@...ux-foundation.org, akpm@...ux-foundation.org, alan@...rguk.ukuu.org.uk, Ian Campbell <ian.campbell@...rix.com>, Konrad Rzeszutek Wilk <konrad.wilk@...cle.com> Subject: [091/107] xen/timer: Missing IRQF_NO_SUSPEND in timer code broke suspend. 2.6.32-longterm review patch. If anyone has any objections, please let us know. ------------------ From: Ian Campbell <Ian.Campbell@...rix.com> 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.
