The patch titled
Compress stack unwinder output
has been removed from the -mm tree. Its filename is
compress-stack-unwinder-output.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: Compress stack unwinder output
From: Dave Jones <davej@xxxxxxxxxx>
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.
