c0c45bba22 Try to recover from multi-byte messages sent by a target for which we 
get an "Illegal command" (why is this?) when we try to pull it in.
On detection of this condition, we reset the SCSI bus and simply stop asking
this target for an identify messages, for now.

ae4eae4f63 Change reference in asm code from `__mcount'' to `___mcount'', to be 
consistent with the (default) prepending of underscores to identifiers.

Because this reference is inside an ASM string it's too hairy to
conditionalize to support different toolchains that don't prepend underscores.
(Just don't do profiling with  such  toolchains.)

4175c2819f Redo 3MAX+ (5k/240) interrupt enable code. 
Instead of being a no-op, kn03_intr_enable() sets the sw copy of the
interrupt-enable mask *and* writes it into the IO asic intr-enable
register.  Boot code sets the sw copy (kn03_tc_imask) to something
sane (KN03_IM0, with tc option slots turned off).  Tested and works.
Interrupt code for other IOASIC machines should be redone so that
interrupts for devices are enabled by drivers, rather than by
cpu-specific boot code.  Functions common to all IOASIC machines
(PSWARN?) should be done by asic_init().

Checked in without the above changes so that 3MAX+, MAXINE and 3MIN
interrupt-(enable,handle) can converge.

eb4cd26383 from the comments at the top of the file: 
INSTALL -- somewhat generic kernel with a snowball's chance of
	   fitting on an install floppy.

This kernel MUST consist (for users' sanity) of a subset of
the GENERIC configuration.  It also should support X reasonably
(though the SysV SHM extensions won't work).

To avoid a maintenance nightmare, this kernel consists of GENERIC
with missing options/devices/etc. REMOVED rather than commented
out.  That makes it easy to diff agains GENERIC, to make sure that
it really is a subset of the functionality.

03c9dc7a48 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.

64b99b333d 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.)

be2c7f3d13 If we panic inside trap(), Do a stack traceback before printing the trap log. 
Also change the stack-traceback code to avoid having multiple returns
(and thus multiple stack pops) because with gcc -O2 that breaks the
heuristic that a "jr ra" preceding the PC precedes code to push the
current stack frame.  Which breaks stacktrace() before it even
traces past itself :-(.  Use a goto instead.

fb9f07db36 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
got the last one wrong.  Also print some functions (e.g., trap handlers)
by name.  Add hook to use something other than printf() as the output
function, e.g,. for kernel debugging.
Tested with the `native' toolset, but not ELF format kernels.
(i.e., unwinding the $GP register is not tested.)

The stack backtrace code that interprets and unwinds stackframes is still
opaque and stylistically awkward.
