Interrupt exit is a natural place to stop the tick: it happens after all events happening before and during the irq which are liable to update the dependency on the tick occured. Also it makes sure that any check on tick dependency is well ordered against dynticks kick IPIs. Bring in the infrastructure that performs the tick dependency checks on irq exit and shut it down if these checks show that we can do it safely.
