Ravi Bangoria efc9c05681 perf stat: Correct --no-aggr description 
Description of --no-aggr in perf-stat man page is outdated. --no-aggr
can also be used while profiling specific set of cpus. For ex,

  $ perf stat -e cycles,instructions -C 1-2 --no-aggr -- sleep 1

    Performance counter stats for 'CPU(s) 1-2':

    CPU1   5,94,92,795   cycles
    CPU2   2,69,72,403   cycles
    CPU1   2,02,08,327   instructions   # 0.34 insn per cycle
    CPU2     73,17,123   instructions   # 0.12 insn per cycle
