Subject: [PATCH 2/3] Move generic dwarf2 operations from x86 to asm-generic
Date: Tue, 7 Oct 2014 14:27:13 -0500 [thread overview]
Message-ID: <1412710034-16908-3-git-send-email-minyard@acm.org> (raw)
In-Reply-To: <1412710034-16908-1-git-send-email-minyard@acm.org>
From: Corey Minyard <cminyard@mvista.com>
A lot of arch/x86/include/asm/dwarf2.h was generic, move it to
asm-generic so other arches can get to it.
