From 0440d4c00dadf8b97657c0864e4d54a088430de8 Mon Sep 17 00:00:00 2001 From: Joerg Roedel Date: Wed, 24 Oct 2007 12:49:50 +0200 Subject: x86 gart: rename symbols only used for the GART implementation This patch renames the 4 symbols iommu_hole_init(), iommu_aperture, iommu_aperture_allowed, iommu_aperture_disabled. All these symbols are only used for the GART implementation of IOMMUs. It adds and additional gart_ prefix to them.
