That extra aligning or offset is to work around ISA devices: When one bridge have several children devices, and every device has several io port resources and resource size < 0x400. We need to check size, and add extra size to make sure bit8/9 to be zero. -- 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/
