but we may need another hazard barrier toUrgently. We need some ticks to wait until counter state machine has been updated. The amount of ticks may occasionally be the same as in case of back_to_back_hazard for some cpus. It's completely different for others, I sure. Original compare_change_hazard waits up to 12 ticks for r4k. While I don't think this amount should depend on irq_disable_hazard as old code assumes, we may still need 12 or so ticks for old cpus.
replace back_to_back_c0_hazard().
