Ok, here's my proposed fix, which appears to work with preempt.  I haven't
tested on non-preempt, nor (obviously since its from me) SMP.  However,
I forsee no problems caused by this change.

release_dev() sets filp->private_data to NULL when the tty layer has
done with the file descriptor.  However, it remains on the tty_files
list until __fput completes.

Add "seqlock" infrastructure for doing low-overhead optimistic reader
locks (writer increments a sequence number, reader verifies that no
writers came in during the critical region, and lots of careful memory
barriers to take care of business).

Make xtime/get_jiffies_64() use this new locking.

Trivial patch from Randy Dunlap <rddunlap@osdl.org> removes some useless
error/retval assignments.

Found by inspection of of the x86_64 gettimeofday.

The problem is that the code always records the maximum value
but it is not reset on the next clock tick.  As written, I see it
keeping the maximum number of microseconds since the last clock tick.

The Stanford Checker identified a memory leak in init/do_mounts.c.

This corrects it.

Defaulting to building modules together with vmlinux when just doing
"make" or "make all" is only a good choice when "CONFIG_MODULES" is set.

The updates to use 64-bit jiffies broke fs/proc/proc_misc.c for
architectures still using a 100 Hz clocktick (e.g.  UML)

This prevents reporting processes as having started in the future, after
32 bit jiffies wrap.

Use 64 bit jiffies for reporting uptime.

Provide a sane way to avoid unneccessary locking on 64 bit platforms,
and a 64 bit analogous to "jiffies_to_clock_t()".

 - conversion of remaining drivers to generic device model
 - more of sfr's compat stuff
 - eliminate some bogus syscalls
 - update for MUX driver
 - beginnings of new module code
 - tell the keyboard driver about CONFIG_PARISC

Thanks to John Moses <jmoses@lanl.gov> for the information.

This patch clears out the device queue when a unit is removed.

This code implements the setting of devices offline during the removal
phase.

This patch makes us hold the host reference count a little bit longer in
the /proc interface code.  We were releasing it too early before.

  speedtouch: reject outgoing packets earlier when the firmware is not loaded.

  speedtouch: allocate send urbs in udsl_usb_probe rather than in udsl_usb_data_init.
  Since this diminishes udsl_usb_data_init down to almost nothing, roll it into the one
  place it was used.  Get rid of the semaphore Oliver put it - it is no longer needed.

  speedtouch: change data_started to firmware_loaded, which is what it actually
  means, plus some minor related changes.

  speedtouch: a pile of cosmetic changes to make me feel happier (no code changes).

  speedtouch: wait for receive urb completion handlers to finish after calling
  usb_unlink_urb.

  speedtouch: more robust handling of receive urb failure: retry failed urbs whenever
  a new connection is opened.  This should work well with pppd's persist option.

Rediffed version of the original patch - no sk_buff on the stack this time.

  speedtouch: recycle the receive urb's buffer.  Currently, every time a receive urb
    completes, its old buffer is thrown away and replaced with a new one.  This patch
    performs the minor changes needed to reuse the old buffer.

  speedtouch: move all processing of receive urbs to udsl_atm_processqueue.  This has
  several advantages, as will be seen in the next few patches.  The most important is
  that it makes it easy to reuse of the urb's buffer (right now a new buffer is
  allocated every time the urb completes).  By the way, this patch is much smaller than
  it looks: most of the bulk is due to indentation changes.

This patch prints the vendor + product ids of the scanner after it has
been successfully detected.

Also the annoying error message about "Scanner device is already open"
was downgraded to a dbg. Scanning for devices while one scanner device
was open produced several 100 error messages in syslog.
