Somehow I managed to send the wrong version. Here is a patch which fixes
that. (Remove a dev_info() which wasn't supposed to be there, and make sure
that everything is still consistent in the unlikely event that kmalloc()
fails). Just minor cleanups.

Yes, it's the right fix.  Greg, please merge the attached patch,
which will be needed on any big-endian system.

More functions and data that should be static.

Funny you should ask...

While writing those patches I noted a problem, that the USB device tree
can change while a process reading /proc/bus/usb/devices is traversing it,
leading to an oops when a pointer to a no-longer-existing child device is
dereferenced.  The ensuing discussion led to the conclusion that the
devices' ->serialize locks should be acquired, top-down, while going
through the tree.

That means changing the code that populates the devices file and changing
the code that adds and removes USB device structures.  This patch takes
care of the first part.  I'm delaying the second part because that section
of usbcore is still under change -- David Brownell's revisions have not
yet been fully integrated.

A similar change should be made to usb_find_device() and match_device() in
usb.c.  You may want to add that yourself.

Here is a driver for the usb servo controllers from Phidgets
<http://www.phidgets.com/>, using sysfs.

Note that the devices claim to be hid devices, so I've added them to the
hid_blacklist (HID_QUIRK_IGNORE). A servo controller isn't really an hid
device (or is it?).

Thanks to Dru <andru@treshna.com>, who provided an easy way to reproduce
the problem.

What we have in lib/rwsem.c:__rwsem_do_wake():
	int woken, loop;
	^^^
and several lines below:
	loop = woken;
	woken *= RWSEM_ACTIVE_BIAS-RWSEM_WAITING_BIAS;
	woken -= RWSEM_ACTIVE_BIAS;

However, rw_semaphore->count is 64-bit on Alpha, so
RWSEM_WAITING_BIAS has been defined as -0x0000000100000000L.
Obviously, this blows up in the write contention case.

Fix new ISDN CAPI's internal ncci list semaphore if
CONFIG_ISDN_CAPI_MIDDLEWARE is disabled.

Thanks to Florian Schirmer.

This patch updates support for the Motorola PrPMC750 platform.  Most of the

This patch adds openpic_hookup_cascade(offset, name, handler) which allows for
an arbitrary interrupt controller to be hooked up as a cascade to the openpic.
 This also allows for platforms to just not have a cascaded controller.

On pSeries LPARs we might end up with NUMA nodes that only have memory and
no CPUs.  Only the CPU configuration code actually set a node online, so
memory-only nodes wouldn't show up in sysfs.  Below patch adds the
set_online call to the memory loop too.

The function tcp_send_skb is only called from tcp_fin, and is always called
with force_queue=1.  Therefore, it no longer needs to be global and the code
to send right now can be removed.  Because it always queues, change the
name as well, and fix up the comment.

Can't use _ffs() without first checking for zero, and if bits beyond

This is a revised version of an earlier patch; I feel a lot better about
this one.  Basically it does the same thing as before: allocate
interfaces dynamically to avoid the problems with reusing them.

The difference is that this patch adds a struct kref to the array of
usb_interface_cache's, so the array can persist if needed after the
device has been disconnected.  Each interface takes a reference to it
(along with the configuration itself), so as long as the interfaces
remain pinned in memory the altsettings will also remain.

Here is a slight revision of patch as246b.  This one allocates all the new
interfaces before changing any other state; otherwise it's the same.
