to iterate the PCB list, either for read or write; the PCB lock is
required to access or modify a PCB. To change the binding of a PCB,
both locks must be held.

Add per-IPX PCB mutexes, ipxp_mtx in struct ipxpcb, to protect
per-PCB IPX/SPX state. Add macros to initialize, destroy, lock,
unlock, and assert the mutex. Initialize the mutex when a new
PCB is allocated; destroy it when the PCB is free'd.

one obscure potential license confusion...

fdcontrol/fdcontrol.c:
- Add const constraint to an intermediate value
which is not supposed to be changed elsewhere.
fdread/fdread.c:
- Use _devname in favor of devname to avoid name
conflicit.
- -1 is less than any positive number so in order
to get the block to function, we should get the
block a little earlier.
- Cast to remove signed when we are sure that a
return value is positive, or is compared with
an positive number (tracknumber of a floppy
disk is not likely to have UINT_MAX/2 anyway)
fdread/fdutil.c:
- Use more specific initializer
fdwrite/fdwrite.c:
- Use static on format_track since it's not
referenced in other places.
- Use const char* to represent string constant.
Bump WARNS accordingly.
- Introduce another ng_ether(4) callback ng_ether_link_state_p, which
is called from if_link_state_change(), every time link is changed.
- In ng_ether_link_state() send netgraph control message notifying
of link state change to a node connected to "lower" hook.

place device objects in \ (in this case, PCI links.) Work around this by
starting our probe from \. To avoid attaching system scope objects,
explicitly skip them. (I think it's an ACPI-CA bug that \_SB and \_TZ have
device and thermal object types.) Thanks to pjd@ for testing.

This example caused me to incorrectly believe that you must use the
generic device nodes when you can in fact use either. It's often better
to use the driver specific node.

- Fix the MP Table pci bridge drivers to not probe the configuration table
unless we actually have one. Machines using a default configuration do
not have such a table.
- Only allow default configuration types of 5 (ISA + PCI) and 6 (EISA +
PCI) as the others are not likely to work. Types 1 through 4 use an
external APIC (probably with 80486 processors) which we certainly do not
support, and type 7 uses an MCA bus which has not been tested with the
new MP Table code.
- Correct the fact that the single I/O APIC in a default configuration has
an ID of 2, not 0.
- Fix off by one errors in setting the bus types from the default_data[]
arrays for default configurations.
- Explicitly configure each of the 16 interrupt pins on the sole I/O APIC
when using a default configuration. This is especially helpful for type
6 (EISA + PCI) since the EISA interrupts need to have their polarity
programmed based on the values in the ELCR.
Much thanks to the submitter and tester who endured several rounds of
testing to get this fixed.

complementing the existing special case of a not existing /dev prefix
with the recognition of an already existing /dev prefix.
This implicitly solves the following two issues related to working on
GEOM devices /dev/foo/bar (which have the GEOM provider name "foo/bar")
with the expected commands like "bsdlabel /dev/foo/bar":
1. the error "Geom not found" when trying to write or edit the BSD
label (because previously the incorrect GEOM name "bar" instead of
"foo/bar" was derived from "/dev/foo/bar").
2. the multiple times reported "magically introduced" partition offset
of 63 blocks and the resulting errors like "partition extends past
end of unit" and "partition c doesn't start at 0!".
This implicitly resulted because bsdlabel(8) determines the "MBR
offset" via GEOM and (intentionally) silently falls back to an offset
of 0 if it could not be queried (which is the case if the name was
incorrectly derived).
Usually (at least on PCs) the offset for the first slice is 63 blocks
and bsdlabel(8) automatically subtracts them from the absolute
offsets in the read on-disk BSD label, resulting in the display of an
effective offset of 0. If the GEOM query fails, the assumed offset of
0 is subtracted and an incorrect effective offset of 63 is displayed
and tried to be worked upon.
