I've got:

$ perf stat -e cycles,instructions -a -x,
^C154179453,,cycles,3358275330,100.00,,Ghz,3358275330,100.00
37699562,,instructions,3358350427,100.00,0.24,insn per cycle
,,,3358350427,100.00,,stalled cycles per insn,3358350427,100.00

and it seems this is extra -------------------^^^^^^^^^^^^^^^^^
