a band-aid allowing to call this function savely multiple times, e.g.
during sckbdprobe() and sc_probe_unit(). Otherwise calling it a second
time results in a non-working keyboard. This needs a lot of more work
to actually do the right thing and work like expected.
- Let sunkbd_configure() return the number of the found keyboards, i.e.
1 in case probing succeeds, as it's expected. The return values of the
keyboard configure functions however currently aren't checked so this
doesn't make a difference at the moment.

Use bus_generic_probe() and add a bus_add_child() interface method to
allow device drivers to use the identify method to add themselves if
need be (e.g. syscons(4)).

consist of the expected number of address and size cells (we can't use
dynamic arrays here because at the point in the boot process when this
code is used malloc() doesn't work, yet). This fixes a Fast Data Access
MMU Miss when uart(4) (erroneously) calls OF_decode_addr() to decode
the address of PS/2 keyboards. PS/2 keyboards use a different and also
undocumented scheme at the first parent node than mapping at 'ranges'
properties. It's however not worth implementing that other scheme and
actually also fits atkbdc(4) better to just start at the first parent
node of PS/2 keyboards which is the 8042 controller (I have atkbdc(4)
working that way).

and restoring the metadata. In particular, the metadata-restore
functions now all accept a file descriptor and a pathname. If the
file descriptor is set and the platform supports the appropriate
syscall, restore the metadata through the file descriptor. Otherwise,
restore it through the pathname. This is complicated by varying
syscall support (FreeBSD has an fchmod(2) but no fchflags(2), for
example) and because non-file entries don't have an fd to use in
restoring attributes (for example, mknod(2) doesn't return a file
handle).

When the stack tracer walks up, it looks for magic symbol names to

It was looking for "calltrap". Which of the two symbols you got depended

the newer PCI-based sun4u machines (cosmetic change as they were also
already probed as generic FWOHCI without this). As with gem(4), hme(4)
and ohci(4) detect whether their intpin register is valid and correct
it if necessary, i.e. set the respective IVAR to the right value for
allocating the IRQ resource, as some of them come up having it set
to 0 (in fact in all machines I'm currently aware of the FireWire
part being enabled). This fixes attaching affected controllers.

We can't call KeFlushQueuedDpcs() during bootstrap (cold == 1), since
the flush operation sleeps to wait for completion, and we can't sleep
here (clowns will eat us).
On an i386 SMP system, if we're loaded/probed/attached during bootstrap,
smp_rendezvous() won't run us anywhere except CPU 0 (since the other CPUs
aren't launched until later), which means we won't be able to set up
the GDTs anywhere except CPU 0. To deal with this case, ctxsw_utow()
now checks to see if the TID for the current processor has been properly
initialized and sets up the GTD for the current CPU if not.
Lastly, in if_ndis.c:ndis_shutdown(), do an ndis_stop() to insure we
really halt the NIC and stop interrupts from happening.
Note that loading a driver during bootstrap is, unfortunately, kind of
a hit or miss sort of proposition. In Windows, the expectation is that
by the time a given driver's MiniportInitialize() method is called,
the system is already in 'multiuser' state, i.e. it's up and running
enough to support all the stuff specified in the NDIS API, which includes
the underlying OS-supplied facilities it implicitly depends on, such as
having all CPUs running, having the DPC queues initialized, WorkItem
threads running, etc. But in UNIX, a lot of that stuff won't work during
bootstrap. This causes a problem since we need to call MiniportInitialize()
at least once during ndis_attach() in order to find out what kind of NIC
we have and learn its station address.
What this means is that some cards just plain won't work right if
you try to pre-load the driver along with the kernel: they'll only be
probed/attach correctly if the driver is kldloaded _after_ the system
has reached multiuser. I can't really think of a way around this that
would still preserve the ability to use an NDIS device for diskless
booting.

prevent anything from making calls to the NIC while it's being shut down.
This is yet another attempt to stop things like mdnsd from trying to
poke at the card while it's not properly initialized and panicking
the system.
Also, remove unneeded debug message from if_ndis.c.
