That doesn't appear to be actually used in this file..
Also, since there's already a for_each_possible_cpu() loop in that
proc/stat function, would it yield some code improvement to make
total_forks a cpu_usage_stat?
I guess the whole cputime64_t crap gets in the way of that being
natural...
We could of course kill off the cputime64_t thing, its pretty pointless
and its a u64 all over the board. I think Martin or Heiko created this
stuff (although I might be wrong, my git tree doesn't go back that far).
