Update of /a/cvsroot/src/sys/arch/pmax/pmax
In directory pain.lcs.mit.edu:/b/tmp/cvs-serv14533

Modified Files:
	trap.c locore.S 
Log Message:
Redo the locore interrupt counters reported by vmstat -i:
* add a new enum decstation_intr_t to trap.c, naming each instrumented
  interrupt symbolically, and used to index into intrcnt[].  Change the
  model-specific interrupt handlers to use the decstation_intr_t when
  updating interrupt counters.
* add instrumentation to the kmin and maxine interrupt handlers.
* fix a bug that counted each hardclock interrupts on the kn02 twice.

The hardcoded mapping from locore names to units is gross; but these
counters will hopefully be useful in identifying interrupt hot-spots
and PPP problems on the 3MIN.
