pasemi_mac: enable iommu support Enable IOMMU support for pasemi_mac, but avoid using it on non-partitioned systems for performance reasons. The user can override this by selecting the PPC_PASEMI_IOMMU_DMA_FORCE configuration option. Signed-off-by: Olof Johansson <olof@lixom.net> Signed-off-by: Jeff Garzik <jeff@garzik.org>
