From dd315df1767cf56bd4fb8d730fdff4a3d7e15d84 Mon Sep 17 00:00:00 2001 From: Andi Kleen Date: Thu, 7 Dec 2006 02:14:00 +0100 Subject: [PATCH] [PATCH] x86: Compress stack unwinder output The unwinder has some extra newlines, which eat up loads of screen space when it spews. (See https://bugzilla.redhat.com/bugzilla/attachment.cgi?id=137900 for a nasty example). warning_symbol-> and warning-> already printk a newline, so don't add one in the strings passed to them.
