Urgently. 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.

Could you fix those links, it's broken after you moved git repo in?
