[PARISC] Fix PCI bus numbering in the presence of Cardbus bridges
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.

ieee1394: nodemgr: fix deadlock in shutdown
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 bf74ad5bc41727d5f2f1c6bedb2c1fac394de731,
"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.

- nodemgr_remove_uds() iterated over nodemgr_ud_class.children without
proper protection. This was never observed as a bug since the code
is usually only accessed by knodemgrd. All knodemgrds are currently
globally serialized. But userspace can trigger this code too by
writing to /sys/bus/ieee1394/destroy_node.
- Clean up access to the FireWire bus type's subsys.rwsem: Access it
uniformly via ieee1394_bus_type. Shrink rwsem protected regions
where possible. Expand them where necessary. The latter wasn't a
problem so far because knodemgr is globally serialized.

ohci1394: steps to implement suspend/resume
I did a quick shot on what I described and the appended patch
does the first thing needed for working suspend/resume
in ohci1394 which is HW de- and re-initialisation.
It works with suspend2disk on my Ricoh R5C552 IEEE 1394 Controller
with the 2.6.17 kernel to the extent that if I call dvgrab --interactive
after suspend2disk without unloading ohci1394, it does not lock up
dvgrab with 100% CPU but properly connects to the camera, given
that I first unplug and plug the camera after coming back from
suspend.
I guess that could be fixed by forcing a bus reset in the resume
function.
I cannot test suspend to RAM here at the moment and should
follow the guidelines in Documentation/power/pci.txt also,
so this is rather a quick report than a finished patch and
there are some rough edges:
However, with this patch, I have to unload at least some in-kernel
users of ohci1394 like dv1394 or video1394 before suspending.
Not doing that caused an Oops and a bad tasklet error, probably from
not handling ISO tasklets during suspend/resume properly.
Maybe these can be temporarily cleared or unregistered and
re-registered for suspend/resume with help from the other
layers or from the highlevel 1394 core, but I do not really
know what these do.
But this patch provides a useful base to start from and is
already of much help for people which do not need dv1394
and video1394 or can unload them at least during suspend.
I cannot test function with sbp2 at the moment, but raw1394
