Fix long-standing bug in NetBSD/pmax interrupt initalization on
...
Turbochannel machines with an IOASIC.
After an interrupt is taken, the IOASIC interrupt enable mask is
and'ed with the kernel's interrupt-mask variable. This masks
off any interrupts that were enabled after the hardware interrupt-enable
mask was set. Due to this bug all iynterrupts must be enabled before
the first interrupt is taken. (Interrupts enabled later aren't on in the
ioasic intr-mask register, so they aren't on in (sirm & kernelmask),
which is what used to get written back to the ioasic interrupt-mask
register. Fixed, and tested on on 3MAX+ but not xine/3min.
If this patch perchance breaks on Xines or 3mins, the old code can be
re-enabled by changing the #if 0 in machdep.c to #if 1.

The pmax 3100 interrupt-init code is broken: cpu_startup() enables
...
interrupts before it calls configure(). On 3100s, this can result in
the ethernet interface interrupting before leprobe() is ever called.
Be a bit more defensive in leintr(), where it was dereferencing a null
pointer. This reputedly fixes the oft-reported problems of 3100s not
ooting unless they're on an idle net or had a hard reset done before boot.
(Reworking the config code completely would be nice too.)

traces past itself :-(. Use a goto instead.

Update MIPS stack backtrace code to trace through locore functions,

traps, and interrupts The earlier (4.4bsd) code didn't do the first two, and

function, e.g,. for kernel debugging.
Tested with the `native' toolset, but not ELF format kernels.

(A similar fix needs to be applied to the 3min and xine handlers.

enabled before a handler was set up.
Add interrupt-counting code to model-independent interrupt handler,
and 3max (5k/200) and 3max+ (5k/240) md handlers, for vmstat -i.
Similar changes for 3min and xine are obvious but not done.
Add code for 5k/240 to read, and latch, the current value of the
IOASIC bus-cycle counter at each timer interrupt. The latched
counter is needed to accurately interpolate the bus-cycle counter value
as a high-resolution clock.
