From: Joerg Roedel Date: Wed, 24 Oct 2007 10:49:48 +0000 (+0200) Subject: x86 gart: rename CONFIG_IOMMU to CONFIG_GART_IOMMU X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=966396d3a05c8049fce5c81c49138e5ee1b05443;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git 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.
