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.
Okay miod@.

them going negative - this consists of identifying a number of cases of
IO not going through the buffer cache and marking those buffers with
B_RAW - as well as fixing nfs_bio to show pending writes and reads through
the buffer cache via NFS
still has a problem with mishandling the counters I believe in the
async/sync fallback case where counters stay positive which will be
addressed seperately.

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.

bpf(4) are different enough so that the split makes sense -- this is necessary
to make bpf(4) cloneable.

this allows us to get rid of the dependency of asm_macro.h on asm.h, which
was really only there to bring in psl.h.

more board design-independent.
The main changes are:
- define logical interrupt sources, which match the on-board devices as
well as the seven VME interrupt sources. Use these whenever possible
when registering interrupts in the drivers, so that the actual interrupt
mask layouts are hidden.
- make the on-board and VME interrupt handlers separate. On-board interrupt
handlers are not really associated to an interrupt vector, only to a
given interrupt source, and only one handler can be registered for a
logical interrupt source. On the other hand, VME interrupts come with a
vector number, and can be shared. This allows VME devices to really use
the whole 256 vectors space, starting at vector zero.
- update the real interrupt masks upon interrupt handler registration and
removal, so that only interrupt sources for which a handler exists may
be enabled.
- update the VME interrupt allocation logic to allow exclusive vector
allocation.
- move the Z8536 clock routines to their own file, since they are not
AV400-specific; while there, calibrate the delay constant upon startup
for more accurate delay().
The vme driver is the only one left with AV400 tentacles left, to be fixed
very soon.

the PROM has eaten part of it, so that the reported memory size in dmesg is
a nice round number.

needs to decide on the cpu type at runtime to check quicker, without needing

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..

been years since it has last been used for that purpose, so name it the
initialization/startup stack.
While there, do not store the initialization stack in cpu_info, and have
secondary_pre_main() return its value so that the bootstrap code does not
need to fetch it from cpu_info.
This might be reconsidered when the startup stacks will be freed after they
are not used anymore, but there are more things to do first.

a single ci_flags bitfield.
Also, set_cpu_number() will no longer set CIF_PRIMARY on the primary processor,
it's up to the initialization code to do this.
