Subject: [PATCH 5/16] report ring kernel is running without paravirt
Date: Wed, 31 Oct 2007 16:14:50 -0300 [thread overview]
Message-ID: <1193858130443-git-send-email-gcosta@redhat.com> (raw)
In-Reply-To: <11938581242810-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
