just for the record; I have absolutely no problem with allowing the new cf8 method (I'm assuming that it's obvious that if mmio is available, that will be used instead for performance reasons). What I was/am concerned/uncomfortable about is keying this off the CPU level rather than a PCI level property; I much rather would see this keyed of, say, the PCI ID of the root bridge, or ideally from some PCI property. - 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/
