- Don't use spaces or dots in the eventtimer or timecounter names.
They turn into sysctl node names, and it's just confusing.
- Use comparator #3 instead of #1 for one-shot events. There's an
extra 1-cycle penalty in the hardware for accessing the registers
for comparator 1, no point in paying that penalty.
- Lower the quality of the eventtimer from 1000 to 800, because the
device can't support PERCPU timers and some other device in the system
may be able to provide that.
