- Rename the GART_IOMMU option to IOMMU to make clear it's not just for AMD - Rewrite the help text to better emphatise this fact - Make it an embedded option because too many people get it wrong. To my astonishment I discovered the aacraid driver tests this symbol directly. This looks quite broken to me - it's an internal implementation detail of the PCI DMA API. Can the maintainer please clarify what this test was intended to do?
