Well, I'll probably be maintaining multi-sector PIO externally to the main kernel in that case. 95% of ARM machines have either PIO only or in the case of those that do have PCI DMA support (netwinders) the southbridge is soo messed up that DMA is useless on most boxes produced. Multi-sector PIO is a fundamental requirement that I require. -- Russell King (rmk@arm.linux.org.uk) The developer of ARM Linux http://www.arm.linux.org.uk/personal/aboutme.html - 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/
