[PATCH 4/4] x86 gart: rename symbols only used for the GART implementation

Joerg Roedel
2007-10-24T10:52:07Z

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.
