MD code would free resources that couldn't be freed until we were no
longer running in that processor. However, it's is unused on all
architectures since mikeb@'s tss changes on x86 earlier in the year.

information. This is preliminary work to help eventually supporting the
dual-head ELK model.
Also split the initialization code in several routines, this makes the
code easier to read, and makes it easier to release resources upon failure.
Finally, don't forget to clear the text planes on non-console displays
when initializing.

What happened was that the output of mkdep was fed to a sed expression
that trimmed a bit more than required and also failed to work when
attempting to do make depend with pcc.
Example:
genassym_c.o: /tmp/genassym.whatever ../../../../../sys/param.h \
was changed to:
assym.h: \
but what was intended was:
assym.h: ../../../../../sys/param.h \
For the pcc -M output things were a bit different and after the make
depend the genassym entry would still remain and make would fail. This
affected all platforms except amd64 and sgi.

Right now when mi_switch picks up the same proc, we didn't clear the
flag which would mean that every time we service an AST we would attempt
a context switch. For some architectures, amd64 being probably the
most extreme, that meant attempting to context switch for every
trap and interrupt.
Now we clear_resched explicitly after every context switch, even if it
didn't do anything. Which also allows us to remove some more code
in cpu_switchto (not done yet).

of making it dynamic and the smallest value above the former three. Idea

Not sure what's more surprising: how long it took for NetBSD to
catch up to the rest of the BSDs (including UCB), or the amount of
code that NetBSD has claimed for itself without attributing to the
actual authors.

file copies to nfsv2 causes the system to eventually peg the console.
On the console ^T indicates that the load is increasing rapidly, ddb
indicates many calls to getbuf, there is some very slow nfs traffic
making none (or extremely slow) progress. Eventually some machines
seize up entirely.

biowait() reads that do *not* come from the buffer cache - we use the
B_RAW flag to identify these at art's suggestion - since it makes sense
and the flag was not being used. this just flags all these buffers with
B_RAW - biodone already ignores returned buffers marked B_RAW.

I am quite sure it has an SGC PROM in addition to the DIO PROM, but I don't
have the hardware to check...

directive can select between MI and MD versions of these files. At
the same time, adjust the boot programs to pick exactly what they need,
instead of the 7 or 8 mechanisms previously used.
There will be some fallout from this, but testing it all by myself is a
ridiculously slow process; it will be finished in-tree.
Various developers were very nice and avoided making fun of me when I
was gibbering in the corner..

So instead of keeping a few loose variables to store the runtime computed
psr bits to use for the logical IPL levels, just keep a complete array of
all psr values. Thus we can have a correct splassert_check().
