the first bad commit commit 336ca196738842764df39fbd4d3f9129179b3e7d Author: Viresh Kumar Date: Mon Mar 31 12:33:21 2014 +0530 hrtimer: Use for_each_active_base() to iterate over active clock bases There are various places where we are currently running a loop of HRTIMER_MAX_CLOCK_BASES iterations. We just run 'continue;' if there are no timers added to a clock base. Instead we can use the new for_each_active_base() routine to iterate over only the bases which are currently active. This also updates hrtimer_interrupt() which was earlier modified to use ffs(active_bases) directly.
