reading the native disklabel. This ensures cylinder alignment.
Fix disklabel to do cylinder alignment arithmetic correctly in -A
mode. Worked by accident before, since the code was protected by
D_VENDOR, which wasn't being set.

with different locking mechanism. 88110 soft ipi are replaced with an
ipi callback which is checked upon return from exception (it can not be kept
as a softintr, as the generic softinterrupt code doesn't have per-cpu
pending softintr queues).

as additional argument. This will allow intermediate layers between
scsi devices such as sd and scsi host adapters to take appropriate

ensure 'c' always has the correct size as the rest of the kernel
assumes. Thus prevent dd'ing causing a SCSI out-of-bounds error.

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@.

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.

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.

Also, set_cpu_number() will no longer set CIF_PRIMARY on the primary processor,

- Move the functionality of choosing a process from cpu_switch into
a much simpler function: cpu_switchto. Instead of having the locore
code walk the run queues, let the MI code choose the process we
want to run and only implement the context switching itself in MD
code.
- Let MD context switching run without worrying about spls or locks.
- Instead of having the idle loop implemented with special contexts
in MD code, implement one idle proc for each cpu. make the idle
loop MI with MD hooks.
- Change the proc lists from the old style vax queues to TAILQs.
- Change the sleep queue from vax queues to TAILQs. This makes
wakeup() go from O(n^2) to O(n)
there will be some MD fallout, but it will be fixed shortly.
There's also a few cleanups to be done after this.
