If the ipl is lowered here, a machine can rapidly run out of stack
space when it is under heavy interrupt load. Without this fix,
my test machine would fall over within a few seconds when forwarding
14,000 packets/sec. With the patch, it has been up for over 24 hours
and has built the world at the same time.

the countdown register.
this should not be necessary but there are broken laptops that
do not restore the countdown register on resume.
when it happnes, it messes up the hardclock interval and system clock,
which leads to the infamous "calcru: negative time" problem.

directory than the default one. If the option is not given, then the
output of config is exactly as before. Only when an alternate output
directory has been specified will config modify its behavior.
Additional changed:
o Remove the now conflicting and unused NODEV define. It
conflicts with NODEV in sys/param.h.
o Rename the now conflicting MACHINE token to ARCH. It
conflicts with MACHINE in sys/param.h.
o Fix some easy style bugs.
o Fix some easy grammar bugs in the manpage.

eliminate an extra (useless) level of indirection in half of the page
queue accesses and (2) to use a single name for each queue throughout,
instead of, e.g., "vm_page_queue_active" in some places and
"vm_page_queues[PQ_ACTIVE]" in others.

This is one piece of the grand unified PPP daemon concept, whereby using
netgraph nodes enables PPP data to be handled completely in kernel land,
while leaving negotiation/control to be handled by a single user land
daemon, no matter what the link type(s).
This is a safety checkin only; it compiles, but is utterly untested.

Merge the contents (less some trivial bordering the silly comments)
of <vm/vm_prot.h> and <vm/vm_inherit.h> into <vm/vm.h>. This puts
the #defines for the vm_inherit_t and vm_prot_t types next to their
typedefs.
This paves the road for the commit to follow shortly: change
useracc() to use VM_PROT_{READ|WRITE} rather than B_{READ|WRITE}
as argument.
go to REQ_SENT (and we probably should also log this since it should
only happen in a cross-linked connection).

test this support since I don't have the dongle for the card in
question and the dongle I have for my 3C589D doesn't seem to work on
it. I don't know if this is due to the damage I did to the 562 card
in transit from freebsdcon, or a mis-matched dongle...
