-/* How timers work:
- *
- * On uniprocessors we just use counter zero for the system wide
- * ticker, this performs thread scheduling, clock book keeping,
- * and runs timer based events.  Previously we used the Ultra
- * %tick interrupt for this purpose.
- *
- * On multiprocessors we pick one cpu as the master level 10 tick
- * processor.  Here this counter zero tick handles clock book
- * keeping and timer events only.  Each Ultra has it's level
- * 14 %tick interrupt set to fire off as well, even the master
- * tick cpu runs this locally.  This ticker performs thread
- * scheduling, system/user tick counting for the current thread,
- * and also profiling if enabled.

-/* Two timers, traditionally steered to PIL's 10 and 14 respectively.
- * But since INO packets are used on sun5, we could use any PIL level
- * we like, however for now we use the normal ones.
- *
- * The 'reg' and 'interrupts' properties for these live in nodes named
- * 'counter-timer'.  The first of three 'reg' properties describe where
- * the sun5_timer registers are.  The other two I have no idea. (XXX)
