Message-Id: <138b9e1650b385d5ac9d.1233182103@abulafia.goop.org> Date: Wed, 28 Jan 2009 14:35:03 -0800 From: Jeremy Fitzhardinge <jeremy@...p.org> To: Ingo Molnar <mingo@...e.hu> Cc: linux-kernel@...r.kernel.org, Xen-devel <xen-devel@...ts.xensource.com>, the arch/x86 maintainers <x86@...nel.org>, Ian Campbell <ian.campbell@...rix.com>, Zachary Amsden <zach@...are.com>, Rusty Russell <rusty@...tcorp.com.au>, Ravikiran Thirumalai <kiran@...lemp.com> Subject: [PATCH 3 of 7] x86: fix paravirt clobber in entry_64.S The clobber is trying to say that anything except RDI is available for clobbering, but actually clobbers everything. This hasn't mattered because the clobbers were basically ignored, but subsequent patches will rely on them.
