Each platform needs different args, unfortunately.
Sparc needs the extra arg because the device space is described with a base 32-bit address, then an upper 32-bit base to form the full 64-bit address. This upper 32-bit part is called the "io_space" and thus is what gets passed into that 6-th argument. - 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/
