Subject: [PATCH 2.6.21 review II] [10/10] VMI: Paravirt debug defaults off
Date: Sat, 10 Feb 2007 12:52:38 +0100 (CET) [thread overview]

In-Reply-To: <200702101252.033732000@suse.de>
From: Zachary Amsden <zach@vmware.com>
Deliberate register clobber around performance critical inline code is great for

on, so stop making DEBUG_PARAVIRT default on.
