- Add TIMERLAT_ALIGN osnoise option
 
   Add a timer alignment option for timerlat that makes it work like the
   cyclictest -A option. timelat creates threads to test the latency of the
   kernel. The alignment option will have these threads trigger at the
   alignment offsets from each other. Instead of having each thread wake up
   at the exact same time, if the alignment is set to "20" each thread will
   wake up at 20 microseconds from the previous one.
