I don't know of any PC cards that can support ISA DMA channel 4 so I guess simply because of that it hasn't happened. Do you actually know of any DMA 4 capable ISA devices or is it used for onboard ISA devices ?
The ifdef is ugly. There should be a nicer way to do this. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
