It misses a bunch of easy stuff, actually (tons of casts to void * from what used to be unsigned long and is void __iomem * with your patch). I don't see where you handle PIO stuff, though - no ioport_map() _or_ pci_iomap() in sight. Note that ioport_map() is not equivalent to a cast - we add a constant there. How does ioread/iowrite work on the results? - 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/
