The problem is caused by the devfs_mk_dir simplification that went in a

Fix for trivial typo.  Without it, you can't insert anything on top of
agpgart.ko because the agp_register_driver() will erroneously pick up
the symbol version from agp_backend_acquire().

Clean up "pendcount" locking (or rather - lack there-of) by making it a
per-timer thing and thus automatically protected by the timer lock.

Now that the kernel provides code user programs are executing directly
(I mean the vsyscall code on x86) it is necessary to add unwind
information for that code as well.  The unwind information is used not
only in C++ code.

This patch adds a AT_SYSINFO_EH_FRAME ELF aux-table value that points to
the unwinding block description for the sysinfo frame, and makes sure
the AT_* value is passed to applications.  It defines the static data
for the unwind blocks (two, one for int80 and the other for sysenter),
and finally adds code to copy the data in place.

Forward port of Jay's 2.4 patch.
Also I've cleaned up EISA configury - we only need it for
systems with EISA.

While testing our upcoming kernel update for 7.2 alpha, I've encountered
a problem with move_initrd. It allocates a page-aligned chunk to move
the initrd into, but it doesn't allocate the entire last
page. Subsequent bootmem allocations can then be filled from the last
page used be the initrd.  This then becomes a problem when the initrd
memory is released.

The 2.5 kernels may hang on execve(). Most easily this can be reproduced
by submitting forms in mozilla, apparently because it does execve with
very long argument strings.
That's what happens in do_execve, I suppose:
	bprm.mm = mm_alloc();
	...
	init_new_context(current, bprm.mm); here we update current ptbr
					    with new mm->pgd
	...
	copy_strings;
			interrupt -> do_softirq -> switch to ksoftirqd
			...
			switch back to do_execve;
	copy_strings -  immediate page fault in copy_user that we can't
			handle because the new ptbr has been activated
			after context switch and current->mm is not
			valid anymore.

The fix is to not update ptbr for current task in init_new_context(),
as we do it later in activate_mm() anyway.

With it my (UP) boxes look quite stable so far.

This one gets rid of sys32_{get,set}affinity in favor of a unified
compat implementation.

From: Trond Myklebust <trond.myklebust@fys.uio.no>

The patch fixes some problems with NFS under heavy writeout.

NFS pages can be in a clean but unreclaimable state.  They are unreclaimable
because the server has not yet acked the write - we may need to "redirty"
them if the server crashes.

These are referred to as "unstable" pages.  We need to count them alongside
dirty and writeback pages when making flushing and throttling decisions.
Otherwise the machine can be flooded with these pages and the VM has
problems.

The MCE code is setting up a timer whose handler uses the workqueue code
before workqueue is initialised.  If you boot slowly it oopses.

Convert the MCE code to use an initcall.

From: george anzinger <george@mvista.com>

The MAJOR problem was a hang in the kernel if a user tried to delete a
repeating timer that had a signal delivery pending. I was putting the
task in a loop waiting for that same task to pick up the signal. OUCH!

A minor issue relates to the need by the glibc folks, to specify a
particular thread to get the signal.  I had this code in all along,
but somewhere in 2.5 the signal code was made POSIX compliant, i.e.
deliver to the first thread that doesn't have it masked out.

This now uses the code from the above mentioned clean up.  Most
signals go to the group delivery signal code, however, those
specifying THREAD_ID (an extension to the POSIX standard) are sent to
the specified thread.  That thread MUST be in the same thread group as
the thread that creates the timer.

drivers/md/xor.c needs kernel_fpu_begin() for the mmx checksumming functions.
 So export that to GPL modules.

use `unsigned long' for a jiffies-holding type.

use-after-free races have been seen due to the workqueue timer in the tty
structure going off after the tty was freed.

Fix that up by using cancel_scheduled_work() and flush_scheduled_work().

The workqueue code currently has a notion of a per-cpu queue being "busy".
flush_scheduled_work()'s responsibility is to wait for a queue to be not busy.

Problem is, flush_scheduled_work() can easily hang up.

- The workqueue is deemed "busy" when there are pending delayed
  (timer-based) works.  But if someone repeatedly schedules new delayed work
  in the callback, the queue will never fall idle, and flush_scheduled_work()
  will not terminate.

- If someone reschedules work (not delayed work) in the work function, that
  too will cause the queue to never go idle, and flush_scheduled_work() will
  not terminate.

So what this patch does is:

- Create a new "cancel_delayed_work()" which will try to kill off any
  timer-based delayed works.

- Change flush_scheduled_work() so that it is immune to people re-adding
  work in the work callout handler.

  We can do this by recognising that the caller does *not* want to wait
  until the workqueue is "empty".  The caller merely wants to wait until all
  works which were pending at the time flush_scheduled_work() was called have
  completed.

  The patch uses a couple of sequence numbers for that.

So now, if someone wants to reliably remove delayed work they should do:


	/*
	 * Make sure that my work-callback will no longer schedule new work
	 */
	my_driver_is_shutting_down = 1;

	/*
	 * Kill off any pending delayed work
	 */
	cancel_delayed_work(&my_work);

	/*
	 * OK, there will be no new works scheduled.  But there may be one
	 * currently queued or in progress.  So wait for that to complete.
	 */
	flush_scheduled_work();


The patch also changes the flush_workqueue() sleep to be uninterruptible.
We cannot legally bale out if a signal is delivered anyway.

- oprofile is currently only profiling one sibling.  Fix that with
  appropriate register settings.

- fix an oops which could occur if the userspace driver were to request a
  non-existent resource.

- in NMI handler counter_config[i].event is accessible from user space so
  user can change the event during profiling by echo xxx >
  /dev/oprofile/event

- event mask was wrong, the bit field is 6 bits length not 5, events
  SSE_INPUT_ASSIST and X87_SIMD_MOVES_UOP was affected by masking high bit of
  event number.

A few places were missing the rwlock->spinlock conversion.
