Martin Diehl pointed out that the network layer treats
a tx drop notification in special ways, so "usbnet"
shouldn't be using them.  This fixes that problem,
which could potentially explain some infrequent oopsing
seen in the network layer.  (With memory so tight that
an URB can't be gotten.)

Please merge.

This fixes a problem that's been around for some time:
usbcore will sometimes use un-initialized memory as if
it holds a valid language code.

This fixes a minor error in usb-skeleton's disconnect() routine: if the
interface's private data is NULL, the current code exits without releasing
the disconnect_sem semaphore.

I removed the test entirely because I can't think of any situation where
that private data actually would be NULL, other than a pretty badly
malfunctioning system.  Why test for something that should never happen?
And if it does happen, we shouldn't want the disconnect routine to fail
silently -- we should want to see a nice big segfault (when the NULL
pointer is dereferenced) so that we can find and fix the underlying error.

Is there any sort of convention (a la Documentation/CodingStyle) about
whether this approach should be used in general?  There are _lots_ of
places in the kernel where unnecessary checks for NULL pointers are made.

This patch makes the Datafab and the Freecom driver both use the I/O safe
buffer us->iobuf instead of local stack or local allocations.

This patch makes the 2.5 initializers use the DMA-safe us->iobuf instead of
local stack or local dynamic allocation.

A couple of patches for the ftdi_sio driver on 2.5.73

"2.5.73-ftdi_sio-bigupdate.patch" - this is a big, ugly patch to
bring the ftdi_sio driver in line with what recently submitted for
inclusion in the 2.4.x kernel
(v2.4/testing/cset/cset-abbotti@mev.co.uk|ChangeSet|20030627190202|35624.txt),
but with necessary changes for 2.5.x.  I've bumped the driver's
version number to 1.4.0 to distinguish it from that submitted for
the 2.4.x kernel.

"2.5.73-ftdi_sio-dynamicwrite.patch" - this adds to the above patch
to replace the pool of urbs used for writes with dynamically
allocated urbs and transfer buffers.  I've tested this on the
FT8U232AM and FT232BM and I think I've catered for the older "SIO"
device, but I don't have a device to test that.  Also, it is not
safe to unload the driver module while write urbs are in flight
(same as for the Visor driver).

Here is the blind flight :-)
===
drivers/usb/class/usblp.c
usblp->dev was set to NULL to indicate a device disconnect but we need
this value for usb_buffer_free() when device is still opened and cleanup
is delayed until usblp_release().
We have a usblp->present now for preventing device read, write, open and ioctl.

- CPUFREQ_ALL_CPUS is not a valid argument any more, don't mention it
  in include/linux/cpufreq.h
- without a driver->init() function a cpufreq driver isn't even
  loaded, so remove that check in the per-CPU initialization
- whitespace and clarification changes to linux/cpufreq.

All from Dominik again..

Wait with the destruction of cpufreq objects until all references
are gone (code partly based on rmk's comparable patch for the PCMCIA

 - export the __div64_32 symbol for modules;

 - add likely() to the fast path (divisor>>32 == 0);

 - add __attribute__((pure)) to __div64_32() prototype so
   the compiler knows global memory isn't clobbered;

 - avoid building __div64_32() on 64bit architectures.

* whitespace cleanup
* removal of unused members of netdev priv struct
* extendable arrangement of h/w reset logic

* Perf cleanup: s/int/unsigned int/ for descriptor ring indexes
  [suggestion by Jeff Garzik].
* Perf cleanup: cache references to ring elements using local pointer

* h/w workaround: several 10's of thousands of 82547 controllers where
  mis-fused during manufacturing, resulting in PHY Tx amplitude to be
  too high and out of spec.  This workaround detects those parts, and
  compensates the Tx amplitude by subtracting ~80mV.

* Cleanup: ethtool diags: only reset if not if_running.

* Bug fix: alloc_etherdev failure didn't cleanup regions in probe.

* Bug fix: missing Tx cleanup opportunities during interrupt handling.

* Bug fix: fix VLAN support on PPC64 [Mark Rakes (mrakes@vivato.net)]
