[SCSI] Re-do "final klist fixes"

With the previous commit that introduces the klist enhancements, we can
now re-do 2b7d6a8cb9718fc1d9e826201b64909c44a915f4 again.

[PATCH] fix klist semantics for lists which have elements removed on traversal

The problem is that klists claim to provide semantics for safe traversal of
lists which are being modified.  The failure case is when traversal of a
list causes element removal (a fairly common case).  The issue is that
although the list node is refcounted, if it is embedded in an object (which
is universally the case), then the object will be freed regardless of the
klist refcount leading to slab corruption because the klist iterator refers
to the prior element to get the next.

The solution is to make the klist take and release references to the
embedding object meaning that the embedding object won't be released until
the list relinquishes the reference to it.

(akpm: fast-track this because it's needed for the 2.6.13 scsi merge)

[PATCH] pivot_root() circular reference fix

Fix http://bugzilla.kernel.org/show_bug.cgi?id=4857

When pivot_root is called from an init script in an initramfs environment,
it causes a circular reference in the mount tree.

The cause of this is that pivot_root() is not prepared to handle pivoting
an unattached mount.  In an initramfs environment, rootfs is the root of
the namespace, and so it is not attached.

[PATCH] kprobes: fix handling of simultaneous probe hit/unregister

This patch fixes a bug in kprobes's handling of a corner case on i386 and
x86_64.  On an SMP system, if one CPU unregisters a kprobe just after
another CPU hits that probepoint, kprobe_handler() on the latter CPU sees
that the kprobe has been unregistered, and attempts to let the CPU continue
as if the probepoint hadn't been hit.  The bug is that on i386 and x86_64,
we were neglecting to set the IP back to the beginning of the probed
instruction.  This could cause an oops or crash.

This bug doesn't exist on ppc64 and ia64, where a breakpoint instruction
leaves the IP pointing to the beginning of the instruction.  I don't know
about sparc64.  (Dave, could you please advise?)

This fix has been tested on i386 and x86_64 SMP systems.  To reproduce the
problem, set one CPU to work registering and unregistering a kprobe
repeatedly, and another CPU pounding the probepoint in a tight loop.

does not find its corresponding kprobe, then we check to see if the
original instruction got replaced with other than break.  If it got
replaced with other than break instruction, then we continue to execute
from the replaced instruction, else if we find that it is still a break,
then we let the kernel handle this, as this might be the break instruction
inserted by other than kprobe(may be kernel debugger).

There are possible race conditions if probes are placed on routines within the

on get_kprobe() routines, the system can hang while inserting probes on any
routine such as do_fork().  Because while inserting probes on do_fork(),

get_kprobe() routine and to handle probe of get_kprobe(), kprobes_handler()
gets executed and tries to grab kprobes spin lock, and spins forever.  This
patch avoids such possible race conditions by preventing probes on routines
within the kprobes file and routines used by kprobes.

I have modified the patches as per Andi Kleen's suggestion to move kprobes
routines and other routines used by kprobes to a seperate section
.kprobes.text.

Also moved page fault and exception handlers, general protection fault to
.kprobes.text section.

These patches have been tested on i386, x86_64 and ppc64 architectures, also
compiled on ia64 and sparc64 architectures.

[PATCH] Fix smsc_ircc_init return value

I noticed a strange return value in smsc_ircc_init in
drivers/net/irda/smsc_ircc2.c in rc4-mm1.

When reaching the line "if (ircc_fir > 0 && ircc_sir > 0)", ret is 0.  So I
don't see the point of setting it to 0 in the "else" case.  >From what I
see in 2.6.12 it should probably be set to -ENODEV at the begining of the
"else" case.  The attached patch does this.

Note that I didn't actually see any breakage caused by this.

and we have sent wrong data to disk...  We now clean the dirty buffer flag
under buffer lock in all cases and hence we know that whenever a buffer is
starting to be journaled we either finish the pending write-out before
attaching a buffer to a transaction or we won't write the buffer until the
transaction is going to be committed.

The test in jbd_unexpected_dirty_buffer() is redundant - remove it.
Furthermore we have to clear the buffer dirty bit under the buffer lock to
prevent races with buffer write-out (and hence prevent returning a buffer with
IO happening).

[PATCH] kjournald: missing JFS_UNMOUNT check

It seems that kjournald() may be missing a check of the JFS_UNMOUNT flag
before calling schedule().  This showed up in testing of OCFS2 recovery
where our recovery thread would hang in journal_kill_thread() called from
journal_destroy() because kjournald never got a chance to read the flag to
shut down before the schedule().

Zach pointed out the missing check which led me to hack up this trivial
patch.  It's been tested many times now and I have yet to reproduce the
hang, which was happening very regularly before.

<mild rant>
I'm guessing that we could really use some wait_event() calls with helper
functions in, well, most of jbd these days which would make a ton of the
wait code there vastly cleaner.
</mild rant>

As for why this doesn't happen in ext3 (or OCFS2 during normal
mount/unmount of the local nodes journal), I think it may that the specific
timing of events in the ocfs2 recovery thread exposes a race there.
Because ocfs2_replay_journal() is only interested in playing back the
journal, initialization and shutdown happen very quicky with no other
metadata put into that specific journal.

The code w100fb was based on was horribly Sharp SL-C7x0 specific and there
was little else that could be done as I had no access to anything else with
a w100 in it.  There is no real documentation about this chipset available.

Ian Molton has access to other platforms with the w100 (Toshiba e-series)
and so between us, we've improved w100fb and made it platform independent.
Ian Molton also added support for the very similar w3220 and w3200
chipsets.

There are a lot of changes here and it nearly amounts to a rewrite of the
driver but it has been extensively tested and is being used in preference
to the original driver in the Zaurus community.  I'd therefore like to
