Build the balance mask; it contains only those CPUs that can arrive at this* group and should be considered to continue balancing

907

cpu = cpumask_first_and - return the first cpu from *srcp1 & *srcp2*@src1p: the first input*@src2p: the second input* Returns >= nr_cpu_ids if no cpus set in both. See also cpumask_next_and().(sched_group_span(sg), mask)
