Firmware ignores Cardbus bridges, so when Linux assigns bus numbers,
it must override firmware's notion of what the busses are numbered.
This is not sufficient to support the Cardbus bridge as there is also
no interrupt routing table entry for them.

Willy pointed out the hversion is already stored
in the parisc_device, so I do not need to extract
this information directly from the IODC data.
Also by using the information in the parisc_device
I can avoid re-reading the IODC data for the Muxes
with specifed port counts.

This patch adds a new function to return the actual number
of ports available. Some of the built-in Muxes return the
number of supported ports, but not all of these port are
available for use.

This patch follows the example of the 8250_gsc
driver by probing for specific built-in Mux
cards first. This allows the system to preserve
the correct detection order with multiple Mux
cards.

The following updates are based off a patch from willy:
* Removal of the mux_card list.
* Add the mux_remove function.
Other updates:
* Re-organize the driver structure a bit to make the
mux_init and mux_exit functions more symmetrical.
* Added the del_timer.
* Unregistered the console.
At this point I can insmod, rmmod, and re-insmod the
mux without any failures.

Follow-up to patch "Consolidate driver registering":
Since I plan the lifetime of Linux 2.6.20 to be the deprecation phase
of CONFIG_IEEE1394_EXPORT_FULL_API, it seems fair to keep all previously
exported symbols available with this option until this phase is over.

This patch consolidates some bookkeeping for driver registering. It
closely models what pci_register_driver() does. The main addition is
that the owner of the driver is set, so we get a proper symlink
for /sys/bus/ieee1394/driver/*/module.
Also moves setting of name and bus type into nodemgr. Because of this,
we can remove the EXPORT_SYMBOL for ieee1394_bus_type, since it's now
only used in ieee1394.ko.

If "modprobe ohci1394" was quickly followed by "modprobe -r ohci1394",
say with 1 second pause in between, the modprobe -r got stuck in
uninterruptible sleep in kthread_stop. At the same time the knodemgrd
slept uninterruptibly in bus_rescan_devices_helper. That's because
driver_detach took the semaphore of the PCI device and
bus_rescan_devices_helper wanted to take the semaphore of the FireWire
host device's parent, which is the same semaphore. This was a regression
since Linux 2.6.16, commit bf74ad5bc4,
"Hold the device's parent's lock during probe and remove".
The fix (or workaround) adds a dummy driver to the hpsb_host device. Now
bus_rescan_devices_helper won't scan the host device anymore. This
doesn't hurt since we have no drivers which will bind to these devices
and it is unlikely that there will ever be such a driver. The dummy
driver is befittingly presented as a representation of ieee1394 itself.

There is no manpower available to reform oui.db into a library for use
in more kernel subsystems. The low ratio of usefulness to size and the
occasional need to update oui.db from IEEE's official list suggest to
drop oui.db. I plan to make a userspace script available which
translates the remaining numeric sysfs attributes to names of
organizations.

The queue depth can be read from /sys/bus/scsi/devices/*/queue_depth,
so don't log it. And the hint about speed improvements is misleading,
at least under current kernels. If serialization is switched off, read
performance is typically increased by less than 10%. (I did not test
write performance recently.) On the other hand, serialize_io=0 is not
yet safe due to some implementation issues that are not trivial to fix.
