CONFIG_DMA_REMAP_TABLE CONFIG_DMA_REMAP CONFIG_IRQ_REMAP That way we'd get the 'DMAR tables' via CONFIG_DMA_REMAP_TABLE - on top of which enabling CONFIG_DMA_REMAP and CONFIG_IRQ_REMAP would enable and handle various hw remapping features. (Does anyone else have better/other code structure suggestions?) But yes, we should first do this rename/cleanup to clarify what it all means, then fix whatever config-combos don't work perfectly yet.
