Well, I've no plans to rewrite that bit of PCMCIA anytime soon, especially as my time is very precious over the next two months or so. Remember that PCMCIA effectively has its own IRQ router which requires the PCMCIA code to know which IRQs are physically connected and which aren't. Unfortunately, there's no way to get that information as far as I know except by the published method in the code. So even if I had time to look at this, I doubt anything would change. I think it's a necessary evil. -- Russell King Linux kernel 2.6 ARM Linux - http://www.arm.linux.org.uk/ maintainer of: 2.6 PCMCIA - http://pcmcia.arm.linux.org.uk/ 2.6 Serial core - 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/
