This currently prints out the maximum number of CPUs the
kernel is configured to support, instead of the actual
number that the kernel brought up. Which results in odd
displays that look like you have more CPUs than you do.

Why do you have to declare a new variable? Can't you just do this? i is
already counting how many cpu's we've brought up and its of the same type j.

CPU numbering is allowed to be sparse. Besides, i still
counts up to NR_CPUS even if CPU numbering isn't sparse.
