* Delete pmax-specific functions and declarations from trap.c
* Delete mips-geeneric functions and declaratinos from pmax_trap.c
* Rename the function pointer used to handle hardware interrupts to
"mips_hardware_intr". Define it in trap.c. Change references elsewhere,
including machdep.c.
Verified to boot on a 5000/200.
* Add spl4() and spl5() functions from the Pica port.
* Add MachFPTrap() as an alternate entry point for MachFPInterrupt.
The r4k reports floating-point execptions as a trap, not an interrupt,
and the Pica port uses the name MachFPTrap().
* Add nops to the Mach_spl?() functions and MachFPInterrupt, as required
for the r4k port.
Commit "floppy" interrupt counter for vmstat -i.
always be eight digits.
Copy the kn02 memory-interrupt reporting function to the kn03 (5k/240)
memory-error handler, since the 3MAXPLUS seems to use the same ECC hardware
as the 3MAX.
to mips/include/asm.h.
Until all references to <machine/machAsmDefs.h> in the pmax and
pica tree are changed to use <mips/asm.h> directly, just do
#include <mips/asm.h>, for compatibility.
Update the include-idempotency preprocessor token to match.
References to machAsmDefs in vendor (sprite, 4.4bsd) headers left unchanged,
for historical accuracy.
* Display as much revision info as we can get.
* Fix a race condition that could cause interrupts to be lost.
* Handle `out of mailbox' conditions (much) more gracefully.
* Schedule timeouts more safely.
* Add diagnostic code to (correctly) detect if a CCB times out before its
outgoing mailbox is emptied.
provide r3k and r4k versions of each, and move to sys/arch/mips/include.
Note in comments where each mips-based port should provide
definitions in its own cpu.h after including this file.
opcodes from the Pica port. Per Fogelstrom claims the latter are all
supposedly MIPS-II (r6000) instructions, rather than MIPS-III (R4000),
but we haven't checked to be sure. Are LL/SC really in MIPS-II?

code following the MIPS ELF abi.
* Move the kn01 interrupt handler outside of #ifdef DS5000, to support
3100-only kernels.
* Add #ifdef DS3100 around kn01_enable_intr() to allow configuring
turbochannel-only kernels.
Configuration-time support for specific models of DECstation still needs
more thought/work.
