[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. [AK: redone for new code] Signed-off-by: Dave Jones <davej@redhat.com> Signed-off-by: Andi Kleen <ak@suse.de>
