Update of /a/cvsroot/src/sys/arch/hp300/hp300
In directory pain.lcs.mit.edu:/a/var_tmp/cvs-serv28857

Modified Files:
	autoconf.c hpux_machdep.c isr.h locore.s machdep.c vectors.s 
Added Files:
	isr.c 
Log Message:
New interrupt handling code.  Highlights:
	- Interrupt service routines now take a pointer to
	  the device's softc, rather than a unit number.
	- Interrupt handling code in locore.s condensed.  Only
	  remaining "special" handlers are lev0 (spurious),
	  lev1 (HIL; don't ask), lev6 (clock), and lev7 (NMI).
	  Only remaining hard-coded device driver reference in
	  locore is HIL.  (clock doesn't count...)
	- "dcafastservice" eliminated.  DCA driver has new mechanism
	  to guarantee prompt interrupt service at any ipl (not
	  just level 5).
	- Interrupt code pulled out of autoconf.c and machdep.c and
	  placed in new file, isr.c
