Add a patch to fix Intel E100 wake-on-lan problems.

[ipfire-2.x.git] / src / patches / suse-2.6.27.31 / patches.arch / s390-01-05-kmsg-v3.patch

From: Gerald Schaefer <geraldsc@de.ibm.com>
Subject: Kernel message catalog infrastucture and message generation
References: bnc#417300

Instrument the kernel components such that a kernel message catalog as well as
related man pages can be automatically generated.

This patch now uses pr_xyz instead of kmsg_xyz and there is no Tag anymore
inside the doc file.

Acked-by: John Jolly <jjolly@suse.de>
