USB test driver

Query for stringlen before reading a string in usb.c

usb_hotplug()' prototype doesn't match when CONFIG_HOTPLUG is not defined.

  device ID fix

set_mac_address is now added to the driver.  thanks to Orjan Friberg <orjan.friberg@axis.com>
the actual writing to the eeprom is disabled by default

uncalled for kernel verbiage.

I see you just applied my patch to make destroy_workqueue do the
flush.  Fix up XFS for it.

into penguin.transmeta.com:/home/penguin/torvalds/repositories/kernel/linux

This is a huge performance drop for SMP, but at least XFS is working
again.  Expect a better solution soon.

This is the next iteration of the workqueue abstraction.

The framework includes:

 - per-CPU queueing support.

on SMP there is a per-CPU worker thread (bound to its CPU) and per-CPU
work queues - this feature is completely transparent to workqueue-users.
keventd automatically uses this feature. XFS can now update to work-queues
and have the same per-CPU performance as it had with its per-CPU worker
threads.

 - delayed work submission

there's a new queue_delayed_work(wq, work, delay) function and a new
schedule_delayed_work(work, delay) function. The later one is used to
correctly fix former tq_timer users. I've reverted those changes in 2.5.40
that changed tq_timer uses to schedule_work() - eg. in the case of
random.c or the tty flip queue it was definitely the wrong thing to do.

delayed work means a timer embedded in struct work_struct.  I considered
using split struct work_struct and delayed_work_struct types, but lots
of code actively uses task-queues in both delayed and non-delayed mode,
so i went for the more generic approach that allows both methods of work
submission.  Delayed timers do not cause any other overhead in the
normal submission path otherwise.

 - multithreaded run_workqueue() implementation

the run_workqueue() function can now be called from multiple contexts, and
a worker thread will only use up a single entryy - this property is used
by the flushing code, and can potentially be used in the future to extend
the number of per-CPU worker threads.

 - more reliable flushing

there's now a 'pending work' counter, which is used to accurately detect
when the last work-function has finished execution. It's also used to
correctly flush against timed requests. I'm not convinced whether the old
keventd implementation got this detail right.

 - i switched the arguments of the queueing function(s) per Jeff's
   suggestion, it's more straightforward this way.


Driver fixes:

i have converted almost every affected driver to the new framework. This
cleaned up tons of code. I also fixed a number of drivers that were still
using BHs (these drivers did not compile in 2.5.40).

while this means lots of changes, it might ease the QA decision whether to
put this patch into 2.5.

The pach converts roughly 80% of all tqueue-using code to workqueues - and
all the places that are not converted to workqueues yet are places that do
not compile in vanilla 2.5.40 anyway, due to unrelated changes. I've
converted a fair number of drivers that do not compile in 2.5.40, and i
think i've managed to convert every driver that compiles under 2.5.40.

The patch below is a forward-port from 2.4 of a fix that went in to
the 2.4.x PCMCIA code some time back.  It makes sure that that we
request I/O and memory regions from the correct resource (the parent
of the PCMCIA bridge chip, for PCMCIA bridges connected to a PCI bus)
rather than always requesting them from the top-level ioport_resource
or iomem_resource.

Alessandro Suardi and Zlatko Calusic independently reported that
Oracle cannot start on recent 2.5: excellent research by Zlatko
quickly pointed to vm_pgoff buglet in the new split_vma.
