Subject: [PATCH 11/11] asmlinkage, wan/sbni: Make inline assembler symbols visible and assembler global
Date: Tue, 22 Oct 2013 09:12:26 -0700 [thread overview]
Message-ID: <1382458346-24811-12-git-send-email-andi@firstfloor.org> (raw)
In-Reply-To: <1382458346-24811-1-git-send-email-andi@firstfloor.org>
From: Andi Kleen <ak@linux.intel.com>
- Inline assembler defining C callable code has to be global
- The function has to be visible
Do this in wan/sbni
