[merged] lib-turn-config_stacktrace-into-an-actual-option.patch removed from -mm tree

[akpm]

The patch titled
     Subject: lib: turn CONFIG_STACKTRACE into an actual option.
has been removed from the -mm tree.  Its filename was
     lib-turn-config_stacktrace-into-an-actual-option.patch

This patch was dropped because it was merged into mainline or a subsystem tree

------------------------------------------------------
From: Dave Jones <davej@redhat.com>
Subject: lib: turn CONFIG_STACKTRACE into an actual option.

I was puzzled why /proc/$$/stack had disappeared, until I figured out I
had disabled the last debug option that did a 'select STACKTRACE'.  This
patch makes the option show up at config time, so it can be enabled
without enabling any of the more heavyweight debug options.
