    Which means that

    static enum ucode_state request_microcode_fw(int cpu, struct device *device)
    char name[30];


    sprintf(name, "intel-ucode/%02x-%02x-%02x",
    c->x86, c->x86_model, c->x86_mask);

    needs to be changed to the name of the microcode blob you guys use for
    distributing and we can drop the OLD INTERFACE and there'll be no need
    for userspace tools doing anything with the ucode patches.
