Subject: [PATCH] lto, watchdog/hpwdt.c: Make assembler label global
Date: Mon,  5 Aug 2013 15:16:39 -0700	[thread overview]
Message-ID: <1375740999-8097-1-git-send-email-andi@firstfloor.org> (raw)

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

We cannot assume that the inline assembler code always ends up
in the same file as the original C file. So make any assembler labels
that are called with "extern" by C global
