    complete conversion set_bit() -> __cpumask_set_cpu() by 4aaca0e9cd
    
    While converting to __cpumask_set_cpu() was correct, the first argument
    passed should have been corrected to be "cpu" instead of "nr" at once.
    The wrong construct results in problems on systems with relatively few
    CPUs.
