We need to call hrtimer_get_softirq_time() only once for a cpu_base from hrtimer_run_queues(). And it shouldn't be called if there are no timers queued for that cpu_base. Currently we are managing this with help of a variable: gettime. This part of code can be simplified by using cpu_base->active_bases instead. With this we can get rid of the 'if' block from the loop iterating over all clock bases.
