I cannot imagine why it should be that difficult. The PCI subsystem could over a pci_clone_device() or similar function. For all complicated purposes (sysfs etc) the original device could be used, so it would be hopefully not that difficult. The alternative would be to add a new family of PCI mapping functions that take an explicit mask. Disadvantage would be changing all architectures, but on the other hand the interface could be phase in one by one (and nF4 primarily only works on x86 anyways) I suspect the later would be a little cleaner, although they don't make much difference. -Andi - To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
