From 966396d3a05c8049fce5c81c49138e5ee1b05443 Mon Sep 17 00:00:00 2001 From: Joerg Roedel Date: Wed, 24 Oct 2007 12:49:48 +0200 Subject: [PATCH] x86 gart: rename CONFIG_IOMMU to CONFIG_GART_IOMMU This patch renames the IOMMU config option to GART_IOMMU because in fact it means the GART and not general support for an IOMMU on x86.
