[PATCH] PPC64 replace last usage of vio dma mapping routines
From: Paul Mackerras
Date: Fri Feb 04 2005 - 05:27:12 EST
This patch is from Stephen Rothwell <sfr@xxxxxxxxxxxxxxxx>.
This patch just replaces the last usage of the vio dma mapping routines
with the equivalent generic dma mapping routines.
