From the PR:
When 'probe.slot' is PCI_SLOTMAX (== 31) and 'probe.func' is 7,
call to 'pci_cfgread()' here and machine suddenly hangs up.
I don't know why... (or 450GX chipset's bug?)

comments on the same line like so:
device foo # FooInc Brand NetEther cards
Also, move the wireless NIC cards to their own section.
Add commented out wl driver in wireless section.
Remove obsolete or redundant comments about some of the wireless cards
that used to apply but don't since we've removed 'at foobus'.
There should be no functional changes in this change.
happen when the vm system maps past the end of an object or tries
to map a zero length object, the pmap layer misses the fact that
offsets wrap into negative numbers and we get stuck.

- Look for a hardwired interrupt in the routing table for this
bus/device/pin (we already did this).
- Look for another device with the same link byte which has a hardwired
interrupt.
- Look for a PCI device matching an entry with the same link byte
which has already been assigned an interrupt, and use that.
- Look for a routable interrupt listed in the "PCI only" interrupts
field and use that.
- Pick the first interrupt that's marked as routable and use that.
This removes support for booting current kernels with very old bootblocks.
Device driver writers: Please remove initializations for the d_bmaj
field in your cdevsw{}.
<sys/proc.h> to <sys/systm.h>.
Correctly document the #includes needed in the manpage.
Add one now needed #include of <sys/systm.h>.
Remove the consequent 48 unused #includes of <sys/proc.h>.
because it only takes a struct tag which makes it impossible to
use unions, typedefs etc.
Define __offsetof() in <machine/ansi.h>
Define offsetof() in terms of __offsetof() in <stddef.h> and <sys/types.h>
Remove myriad of local offsetof() definitions.
Remove includes of <stddef.h> in kernel code.
NB: Kernelcode should *never* include from /usr/include !
Make <sys/queue.h> include <machine/ansi.h> to avoid polluting the API.
Deprecate <struct.h> with a warning. The warning turns into an error on
01-12-2000 and the file gets removed entirely on 01-01-2001.

- Change the softintr() macro to do nothing on FreeBSD. Previously,
this macro would set a bit in spending and schedule the softinterrupt
thread to run. However, the bs driver never actually registers a
a software interrupt handler, so all this work achieved nothing. From
the code it is not clear what exactly the softintr() macro is actually
supposed to be doing. It looks like it is supposed to be possibly
running the hardware interrupt handler maybe? This handler is only
present in the #ifdef __NetBSD__ code however. I have no idea how this
driver handles interrupts at all, but at least it compiles now.
type of software interrupt. Roughly, what used to be a bit in spending
now maps to a swi thread. Each thread can have multiple handlers, just
like a hardware interrupt thread.
- Instead of using a bitmask of pending interrupts, we schedule the specific
software interrupt thread to run, so spending, NSWI, and the shandlers
array are no longer needed. We can now have an arbitrary number of
software interrupt threads. When you register a software interrupt
thread via sinthand_add(), you get back a struct intrhand that you pass
to sched_swi() when you wish to schedule your swi thread to run.
- Convert the name of 'struct intrec' to 'struct intrhand' as it is a bit
more intuitive. Also, prefix all the members of struct intrhand with
'ih_'.
- Make swi_net() a MI function since there is now no point in it being
MD.
