Subject: [patch 6/6] Add oops_enter()/oops_exit() calls to die().
Date: Tue, 19 Jun 2007 10:45:22 +0200	[thread overview]
Message-ID: <20070619084643.095486838@de.ibm.com> (raw)
In-Reply-To: 20070619084516.457715754@de.ibm.com

[-- Attachment #1: 006-oops-enter.diff --]
[-- Type: text/plain, Size: 1609 bytes --]

From: Heiko Carstens <heiko.carstens@de.ibm.com>

This is mainly to switch off all potentially debugging stuff that
won't report anything useful after an oops happened.
Besided that setting pause_on_oops will work too, but doesn't make
too much sense on s390.
