From 8ea80d783efd0c50577ec8d69757ae54c408eacd Mon Sep 17 00:00:00 2001 From: Joerg Roedel Date: Fri, 11 Jul 2008 17:14:23 +0200 Subject: [PATCH] x86, AMD IOMMU: replace HIGH_U32 macro with upper_32_bits function Removes a driver specific macro and replaces it with a generic function already available in Linux.
