Use the existing calc_delta_mine() calculation for sched_slice(). This saves a divide and simplifies the code because we share it with the other /cfs_rq->load users. It also improves code size: text data bss dec hex filename 42659 2740 144 45543 b1e7 sched.o.before 42093 2740 144 44977 afb1 sched.o.after
