This is v10 post. In this patchset patch 1/3 is added to give more details about nr_cpus and maxcpus in kernel-parameters.txt. This is suggested by Jonathan since the description of them is unclear so that people can't see what's the exact difference between them. Otherwise no big further change for 2/3 and 3/3 which comprise the old post.
