Message-ID: <20110427203805.GI19708@electric-eye.fr.zoreil.com>
Date: Wed, 27 Apr 2011 22:38:05 +0200
From: Francois Romieu <romieu@...zoreil.com>

Subject: [PATCH rfc] atm/iphase : removal of PCI space dereferences.
Mostly PHY access and a few (ugly) debug statements for DMA control.
Signed-off-by: Francois Romieu <romieu@...zoreil.com>
---
Really RFCish. I ought to be able to give it some trivial crash testing.
