2 information:

 - this way (base on nr_cpu_ids, not snprintf) is not extensible.
   when add new printing contents, need modify maximized length.
   if acceptable to you, I will go (or do you have any new ideas?).

 - sorry, I have some internal urgent things to do, so may not finish
   within this week, and I will finish it in this month (2013-10-31).
