There are no drivers in drivers/sfi/, nor will there ever be. I followed the broken topology used by ACPI, which has both drivers and non-driver-platform-dependent-code in drivers/acpi/. I did propose fixing ACPI at one point, but there was no consensus on where platform dependent non-driver code that runs on multiple architectures should live. (eg, where to put drivers/acpi/acpica/*) SFI is largely in the same boat. Though one could argue that all of SFI could live under arch/x86 someplace, though it will be accessed by more than moorestown specific code. cheers, -Len Brown, Intel Open Source Technology Center -- 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/
