Subject: [PATCH 9/25][V3] report ring kernel is running without paravirt
Date: Wed, 15 Aug 2007 09:49:29 -0300 [thread overview]
Message-ID: <1187182282913-git-send-email-gcosta@redhat.com> (raw)
In-Reply-To: <1187182268408-git-send-email-gcosta@redhat.com>
When paravirtualization is disabled, the kernel is always
running at ring 0. So report it in the appropriate macro
