Subject: [PATCH 14/16] x86, asmlinkage: Make dump_stack visible
Date: Mon,  5 Aug 2013 15:02:48 -0700
Message-ID: <1375740170-7446-15-git-send-email-andi@firstfloor.org> (raw)
In-Reply-To: <1375740170-7446-1-git-send-email-andi@firstfloor.org>

From: Andi Kleen <ak@linux.intel.com>

dump_stack is used from assembler code, so make it visible.
