After a 1.5 years sabbatical from preempt-rt we are pleased to
announce a refactored preempt-rt patch against linux-2.6.29-rc4.

The patch is working on x86 (32 and 64bit) but we have not yet updated
ARM, PPC and MIPS (work in progress).

We also dropped some experimental features of the base preempt-rt
queue 2.6.26.8-rt15 simply because we wanted to survive the forward
port over 3 kernel releases with the least amount of surprises. These
features (e.g. multiple reader PI locks) are not essential for the
preempt-rt functionality and need some serious overhaul anyway.

The interested -rt observer might have noticed that we based our work
on the 2.6.26.8-rt15 patch queue and did not pick the git-rt tree
which is based on 2.6.28. The reason for this is that we wanted to pick
the most stable patch queue and the git-rt tree has a lot of rewritten
new code. Our work is not making the work which was done over the last
months in the git-rt tree obsolete, quite the contrary: we want to
provide a stable yet latest-kernel based foundation and integrate those
changes gradually, as they become ready.

The further plan for the new -rt series is to merge it fully into git
and integrate it into the -tip git tree so it gets the same treatment
as all of our -tip based work: fully automated compile and boot
testing. Furthermore an automated multi architecture -rt performance
regression test based on the same infrastructure is currently being
built.

The integration into the -tip tree also allows us to seperate out parts
of -rt which are ready for mainline more easily and integrate them
with our usual propagation to mainline.

The structure of the patches is likely to change over the next days
when we tackle the git integration, but we appreciate your feedback in
the form of comments, bugreports and patches.

Enough said. You can find the new patches at the following location:

  http://www.kernel.org/pub/linux/kernel/projects/rt/

Information on the RT patch can be found at:

  http://rt.wiki.kernel.org/index.php/Main_Page

to build the 2.6.29-rc4-rt1 tree, the following patches should be
applied:

  http://www.kernel.org/pub/linux/kernel/v2.6/testing/linux-2.6.29-rc4.tar.bz2
  http://www.kernel.org/pub/linux/kernel/projects/rt/patch-2.6.29-rc4-rt1.bz2

The broken out patches are also available at the same download
location.

Enjoy !

      Thomas, Ingo

Hi!

I get some sleep while atomic warnings.
I've put the log and my config in attachment.

Note, it's a wicked bug: I can't reproduce it anymore.
I would have been glad to give you an irqsoff trace but I can't :-)

Oh yes I have two other warnings, for the second one, I'm not sure
this is really only present in -rt.

The first one, a lockdep warning:

It booted to runlevel 5, brought up GDM, I logged in and XFCE came up
fine. It wasn't until NetworkManager started dorking around with the
802.11 adapter and started doing WEP things that I got the above
warning. Right after I got this, NetworkManager connected and the
system locked up. Sorry, no traceback from the panic.

I haven't gone far in looking at this, but it looks like we might have
to adjust expectations in the crypto code, since it's probably ok to
be in_irq() in this case, since we're actually in a kthread.

I've attached my config and the dmesg output.

Clark

hm, that's a complex one - we do kfree() from IPI context, dunno why this
never triggered in our testing of -rt1.

that should be harmless - unless you only get it under -rt1.

The patch below might do the trick - it offloads this to a softirq.

From: Ingo Molnar <mingo@elte.hu>
Date: Thu Feb 12 09:06:11 CET 2009

in 2.6.28 generic_smp_call_function_interrupt() grew a kfree(),
which is a rather complex, sleepable method under -rt. But the
IPI code runs as a hardirq - which cannot run such code.

So defer this work to a softirq context instead. It still stays
on the same CPU so the percpu IPI assumptions are upheld.

On a second thought ...

I think we could eliminate the kfree() instead, and keep the
atomicity of IPI cross-calls. Linus expressed doubts about
the IPI kmalloc()/kfree() pair we do in the generic SMP IPI
code, suggesting that it probably does not help performance
all that much - so such a change might be upstream-able as well
and would keep -rt closer to mainline.

ok, it's lightly tested now: it built and booted up fine to X with your config.

no, removing the warning would just hide the real bug.

Could you try the fix below please?

Which comes from:

        if (WARN_ON_ONCE(in_irq()))
                return -EDEADLK;

This warning is surprising, as it clearly comes from a softirq
context.

The in_irq() definition looks like this on -rt:

  #define in_irq()        (hardirq_count() || (current->flags & PF_HARDIRQ))

hardirq_count() is correct, but looking at PF_HARDIRQ's definition in sched.h:

 #define PF_EXITPIDONE  0x00000008      /* pi exit done on shut down */
 #define PF_VCPU        0x00000010      /* I'm a virtual CPU */
 #define PF_HARDIRQ     0x08000020      /* hardirq context */
 #define PF_NOSCHED     0x00000020      /* Userspace does not expect scheduling */
 #define PF_FORKNOEXEC  0x00000040      /* forked but didn't exec */

Reveals that due to a typo it not only overlaps the PF_NOSCHED bit, but
also has a spurious 0x08000000 component.

Move it to a free slot: 0x00000080.

The reason is that when we forward ported the definition, i first moved it
to the 0x08000000 slot - but that slot was already taken. (our PF_ task
flag space is really crowded ...)

Then i moved it to a free spot, 0x20. Or so i thought: a later -rt patch
in the queue introduced PF_NOSCHED which overlapped it.

But the bigger problem was the spurious 0x08000000 component, which overlaps
with:

 #define PF_SOFTIRQ      0x08000000      /* softirq context */

Explaining why the warning triggered in ksoftirqd ;-)

Anyway, my fix should solve this. Do you still see the lockup under X? (make
sure you also have the IPI fix applied, see the patch in this same thread.)

ok, i made it unconditional (not just a PREEMPT_RT hac) and did the
cleanup below on top of it.

I dont think repeat, queued IPIs are all that interesting from a
performance point of view. If they are, it will all be clearly
bisectable.

Now that we dont use the kmalloc() sequence anymore, remove
CSD_FLAG_ALLOC and all its dependencies.

Right, except I really don't like the smp_call_function_many() slow path
that's now the only path.

Rusty did that I think, but he also had some idea on how to fix it, I
think it boiled down to sticking a count in the call data instead of the
full cpumask.

So I'd rather we first fix that code, and then remove the kmalloc
all-together like you propose here.

i tried your config and after a few bootups the warning did trigger.

It's the new resource counter code. The IRQ flags disabling it does
seems a bit dubious to me. Peter, what do you think?

Frederic, could you try the patch below?

I'm sorry for no knowledge about RT. Could you teach me what
local_irq_save_nort() does ?

Hmm, how about just replacaing _irq() with preempt_disable()/enable() ?
xxx_nort() is better ?

AFAIK, these will not be called from irq context. (Added Balbir to CC:)

The fix below addresses a lockdep warning i triggered with your config.

(You could hit this if you try to use s2ram or hibernation or explicit
CPU hotplug ops.)

rq_attach_root() does a kfree() with the runqueue lock held.

That's not a very wise move, fix it.

_nort() will just turn them into NOPs in essence.

The question is, are these local IRQ flags manipulations really needed
in this code, and if yes, why?

Right, I can't see a way around carrying that cpumask, there's just too
much that can go wrong without it.

So it put in unconditionally, how about this?

Subject: generic-smp: remove single ipi fallback for smp_call_function_many()

In preparation of removing the kmalloc() calls from the generic-ipi code
get rid of the single ipi fallback for smp_call_function_many().

Because we cannot get around carrying the cpumask in the data -- imagine
2 such calls with different but overlapping masks -- put in a full mask.

The author may think of use this function from irq-context.

But now, it seems it's better to remove them, Hmm.

Hmm, I think this bit ought to go in rcu_free_call_data(), otherwise we
can have that same race again..

I'd better put a comment in on why we use RCU here.

Ok, I tested it through 3 bootups and it did not triggered.
But it's absolutely not a guarantee, as I said, I tried to reproduce it
with several bootups yesterday and I couln't see it again.

But by reading the warning and your patch, yes it is supposed to solve it :)

BTW, a small thing:
 
> [   45.228589] hardirqs last disabled at (0): [<ffffffff8025449d>] copy_process+0x68d/0x1500
> [   45.228602] softirqs last  enabled at (0): [<ffffffff8025449d>] copy_process+0x68d/0x1500


The reason for which I wanted to send an irqsoff trace is that the above lines are false.

addr2line -e vmlinux ffffffff8025449d
/home/me/linux/rt/linux-2.6.29-rc4/kernel/fork.c:1107  (before your patch)

Which is this area in copy_process:

#ifdef CONFIG_NUMA
	p->mempolicy = mpol_dup(p->mempolicy);
 	if (IS_ERR(p->mempolicy)) {
 		retval = PTR_ERR(p->mempolicy);
 		p->mempolicy = NULL;
 		goto bad_fork_cleanup_cgroup;
 	}
	mpol_fix_fork_child_flag(p); // <-- 1107
#endif

Nothing here disables irq.
That's why I wanted to provide an irqsoff trace. But, heh I only had to read
res_counter_charge() :-)

Anyway, there is a problem with these hardirqs/softirqs last disabled...

copy_process() has:

#endif
	p->hardirq_enable_ip = 0;
	p->hardirq_enable_event = 0;
	p->hardirq_disable_ip = _THIS_IP_;
	p->hardirq_disable_event = 0;
	p->softirqs_enabled = 1;
	p->softirq_enable_ip = _THIS_IP_;
	p->softirq_enable_event = 0;
	p->softirq_disable_ip = 0;
	p->softirq_disable_event = 0;
	p->hardirq_context = 0;
	p->softirq_context = 0;
#endif

the sequence count of 0 basically tells you it hasn't been set yet.

It'll work, but its not mergable upstream like this, it greatly
pessimizes the smp_function_call() performance.

maybe we should initialize it to -1 to make this more apparent?

Oh I see now, thanks Peter.

Or why not set p->{hard,soft}irq_disable_ip = NULL ? (or 0, I don't know its type).

I think the current state makes sense, it reflects the actual state of
copy_process.

It is to reflect the actual state at copy_process(), although I think
here's a little buglet:

ifdef CONFIG_TRACE_IRQFLAGS
	p->irq_events = 0;
#ifdef __ARCH_WANT_INTERRUPTS_ON_CTXSW
	p->hardirqs_enabled = 1;
#else
	p->hardirqs_enabled = 0;
#endif
	p->hardirq_enable_ip = 0;
	p->hardirq_enable_event = 0;
	p->hardirq_disable_ip = _THIS_IP_;
	p->hardirq_disable_event = 0;
	p->softirqs_enabled = 1;
	p->softirq_enable_ip = _THIS_IP_;
	p->softirq_enable_event = 0;
	p->softirq_disable_ip = 0;
	p->softirq_disable_event = 0;
	p->hardirq_context = 0;
	p->softirq_context = 0;
#endif

I think the hardirq_enable/disable_ip should also depend on
__ARCH_WANT_INTERRUPTS_ON_CTXSW.

Wont the first CPU that runs the callback unlock this? And then we run the
risk of two back to back callers on the same CPU, having the second
caller possibly corrupt the first.

No, there's a ref count in there that ensures the last one unlocks it.

But that's still not enough, the global queue is RCU protected.

Suppose you have 4 cpus, and use smp_function_call_mask() to 2 others,
now its possible the 4th is also doing global ipis and is traversing the
global queue.

Therefore, if you remove the cfd when its done, it might be the 4th cpu
is in it trying to iterate to the next entry --> BANG.

The solution used is RCU freeing cfd's. This also means we have to RCU
free the LOCK flag, sadly an RCU grace period is waaaay too long to spin
wait on.

Hence this whole solution is not quite feasible.

There's various alternative solutions, but I'm not quite sure which
makes most sense.

The one I'm currently pondering is using the global queue only for
all-but-self cfd's, this matches the all-but-self ipi APIC case.

For smaller masks we could queue a csd per queue and send single ipis.

We needed the local IRQ flags, since these counters are updated from
page fault context and from reclaim context with lru_lock held with
IRQ's disabled. I've been thinking about replacing the spin lock with
seq lock, but have not gotten to it yet.

Ah, in that case we can get away with _nort I think, as both those
contexts are preemptable on -rt.

Hmm ?  I can't understand. Why we have to disable IRQ here again ?
And,
  - try_to_unmap() is called in shrink_page_list(),  there, no zone->lru_lock.
  - page fault path doesn't hold zone->lru_lock.

My concern is only shmem. But I think it doesn't call charge() within lock, actually.

Thanks,

Clarification :)
  res_counter_charge() is called from
    - page fault 
        => under down_read(mmap_sem), lock_page() may be held.  IRQ=ENABLED)
    - add_to_page_cache
        => under lock_page(), mapping->tree_lock is *not* held, IRQ=DISABLED
    - shmem
        => info->lock is held, we use __GFP_NOWAIT here. IRQ=ENABLED
    - shmem
        => info->lock is *not* held with GFP_KERNEL here, IRQ=ENABLED.
    - migration
        => under lock_page() and mmap_sem, IRQ=ENABLED

  res_counter_uncharge() is called from
    - page_remove_rmap()//(Only when ANON)
         => anon_vma->lock and pte_lock(),lock_page() can be held. IRQ=ENABLED?
    - remove_from_page_cache()
         => lock_page() and mapping->tree_lock is held, IRQ=DISABLED.

Summary:
   "Charge" is considered as heavy operation and the call path is placed where the
    thread can sleep, AMAP.
   "Uncharge" is considered as light operation and call path is under some # of
    spinlocks.

Hi,

It fixes the rt-concerned warning I had.
Now, a new little lockdep info, tell me if you need my config, I changed
it a bit:

Oh and I just tested the tracers.
It seems to run fine for all of them except sysprof.
It passes the self-test but doesn't produce any trace when I manually try.

Not completely sure this is only in -rt so I'm pulling very latest -tip
and will see if I find the same problem there.

About sysprof, it's an -rt problem, I don't see it on -tip.
The sysprof hrtimer callback is never called.

I'm digging to see what is happening.

I didn't put my ftrace_printk at the right place.
It doesn't come from hrtimer.
The problem comes from get_irq_regs() which always returns NULL on the
sysprof hrtimer calback, then the trace is immediately dropped
by sysprof.

That's weird, smp_apic_timer_interrupt() calls set_irq_regs() so
it should find it.

Now I'm preempted by my bed.

Ah, that makes sense - under -rt the default hrtimer execution is to
execute in a softirq context. Could you try the patch below please,
does it fix sysprof?

Subject: rt: sysprof hrtimer fix
From: Ingo Molnar <mingo@elte.hu>
Date: Fri Feb 13 08:22:14 CET 2009

Frederic Weisbecker noticed that sysprof does not work under
.29-rt2, and tracked it down to a NULL result that get_irq_regs()
gives to the sysprof plugin.

The reason for the NULL is that it executes in the HRTIMER_SOFTIRQ
context, hence it does not interrupt any real context and thus
there's no IRQ registers to take a look at.

Since the sysprof functionality is atomic, the fix is to move the
sysprof hrtimers to hardirq context.

Yes! Thanks :-)

Tested-by: Frederic Weisbecker <fweisbec@gmail.com>

So, just a thing.
-rt make the hrtimer's timers running on softirq context because the hrtimer_interrupt
doesn't run as a threaded interrupt, and then it is not preemptible right?

In that case, sysprof will continue to run in hardirq context, as before, and
it will considerably increase the latency. And that matters here.
So I think it is important to put it on the reminder:

-------------------->
Subject: [PATCH] rt: add sysprof to the latency overhead reminder
From: Frederic Weisbecker <fweisbec@gmail.com>

Since sysprof uses the hrtimer on hardirq with interrupts disabled, it
adds a latency overhead.

Add it to the latency reminder.

Not at all.
But when I find some time, I will compare some rt average tests with and without sysprof.

OK, if you really want this, please just change it to:
	unsigned long cpumask_bits[BITS_TO_LONGS(CONFIG_NR_CPUS)];

The 'struct cpumask' will be undefined soon when CONFIG_CPUMASK_OFFSTACK=y,
which will prevent assignment and declaration on stack.

I'd be fascinated to see perf numbers once you kill the kmalloc.  Because
this patch will add num_possible_cpus * NR_CPUS/8 bytes to the kernel which
is something we're trying to avoid unless necessary.

Thanks,
Rusty.

You're free to make it a pointer and do node affine allocations from an
init section of choice and add a hotplug handler.

But I'm not quite sure how perf is affected by size overhead on
ridiculous configs.

No, I meant "can you actually measure the perf win of this patch?".  If you
did so, I missed it?

But if this patch is worthwhile, the right way to do this is make it a
cpumask_var_t, and do the alloc_cpumask_var_node() in that init routine.

Thanks,
Rusty.

Over what, the always single-ipi case, or the kmalloc case?

The thing is, we're removing that kmalloc because its somewhat of a wart
on the whole thing.

Right, and installing a hotplug handler and ... *sigh*

Hi,

Setting CONFIG_PERF_COUNTERS make my build, hang really early. Likely
before ohci1394_dma=early stuff, because firescope doesn't seem to work.

With attached config the system boots up to the point
after /etc/rc.sysinit (this is a fedora 10 system) activates the swap.
Then all I see from upstart/init is "Message from illegal source". And
the system seems to stop the boot process. Strange, isn't it?
 
So this is what I could capture with attached config, by inserting
"/bin/bash" into /etc/rc.sysinit after swap activation:

Hmm, this appears unimplemented on -rt, shouldn't hurt much, but could
be fixed.

Caused by CONFIG_HIGHPTE=y,

as long as TLB flushes are IPIs we really need to disable IRQs for
gup_fast() and thus will either need non-preemptible kmap or disabled
high-pte or disable the gup_fast() fast-path, which would be a shame.

Hi,

Are you interested in these BUG reports?

Without CONFIG_HIGHPTE kernel boots and seems to work correct, but I'm
hitting these two BUGs:

sg_copy_buffer() seems to disable IRQs, however since on -rt everything
is a irq-thread and kmap is preemptible, we don't appear to have that
need.

CC'd everybody who ever touched the file.

With above patch I get a lot of warnings in

could you edit lib/scatterlist.c line 395 and remove this line:

                        WARN_ON(!irqs_disabled());

?

FYI:

These patches in RT2:

rt-fix-ipi-kfree-introduce-ipi_softirq.patch
rt-fix-ipi-kfree-introduce-ipi_softirq-cleanup.patch

Cause a hard-lock when running dhcp on my 8-way AMD box.

Reverting them eliminates the issue.

These work with 2.6.29-rc4-rt2.

Also fixes serial console stall.

I applied them before RT and had to tweak these patches:

preempt-realtime-ipi-call-lock-raw.patch
preempt-realtime-x86_64.patch

Thanks!

I got this warning, that i never saw before with a non rt-preempt
kernel. But maybe it's just coincidence...

Hi,

It's an known issue on ath5k (or 80211):
http://patchwork.kernel.org/patch/1169/

So not preempt-rt related. Perhaps it has been fixed in -rc5.

If it works for you without (plain .29-rc6), then it ought to work with.

Hi,

Should suspend&resume to ram work with this patchset applied?

plain .29-rc6 suspends and resumes just fine.
but .29-rc6-rt3 suspends just fine, but never resumes.
Is there an early_dma thing for the resume path for 1394?

Hi 

It is great to see that the -rt patchset is moving again.

> http://www.kernel.org/pub/linux/kernel/projects/rt/patch-2.6.29-rc7-rt1.bz2
This should be 
http://www.kernel.org/pub/linux/kernel/projects/rt/patch-2.6.29-rc7-rt1.patch.bz2  

As far as i understand this is again for x86. I tried some patches to get the 
ARM platform working as the platform i am working on (phytec i.mx31) is not 
supported by the stable 2.6.26-rt release. The attached patches are for 
reference only as i think some of them are on their way via the pengutronix 
git tree and others are just hacks to get this thing compile. These patches 
enable rt functionality as tested with cyclictest but the kernel is not 
stable, so some pieces are missing.

So my question is, what pieces are missing on the ARM platform to get it working?

Regards
Tim

The following patches are against the 2.6.29-rc4-rt2 in an attempt to get ARM working.

I didn't need this anymore for -rc7-rt1.

I suggested a better fix already last time.  Moreover I think imx isn't
coherent.

Doing this in arch/arm/include/asm/bitops.h is less intrusive and it
seems to me the better place.  See my patch stack.

It would be easier to check your patch if it didn't contain reverts of
earlier changes.

on top of 2.6.29-rc7-rc1 I did some ARM related fixes that you can find
at

	git://git.pengutronix.de/git/ukl/linux-2.6.git v2.6.29-rc7-rt1-pu

The top commit currently isn't pretty as it contains several independant
fixes.  Some of them are netX specific so you probably don't need them,
but they shouldn't hurt you either.

I will update this branch as I continue working in a non-fast-forward
manner.  I use TopGit to manage this branch, you might want to use it,
too, if you intend to follow my work.

My status quo is:

	Testing tracer sched_switch: PASSED

	FAILED!

The warning is triggered here because tracing_start is called twice in
trace_selftest_startup_preemptirqsoff's error path[1].

I researched for some time now why the tracers doesn't pass the
self-tests, but without success.  It's bed time and any hints are
welcome.

Other than that my machine boots and reports from time to time

	scheduling while atomic

and

	sleeping function called from invalid context at kernel/rtmutex.c:683

Both errors probably happen because some spin_locks need to be converted
to raw_spin_locks.  Will look later.

I provide this uncooked state to prevent duplicate work, so please
excuse the bad code and commit history.  If it upsets you, please send
patches :-)

Best regards
Uwe

[1] if trace_test_buffer sets count = 0 or returns != 0 in
kernel/trace/trace_selftest.c:440, the code flow is:

	tracing_start()
	goto out;

	...
out:
	trace->reset(tr);
	tracing_start();

I think the last tracing_start is wrong, but I didn't check deeply.

I still have this problem.  I digged into irqsoff without finding the reason.

Looking at trace_selftest_startup_irqsoff I saw that
trace_buffer_lock_reserve is called thrice successfully.

Steven (or someone else of course), do you can give me a hint?

Up to now I didn't try to do much with my system, but just booting
doesn't yield such BUGs or Warnings anymore.

We are pleased to announce the next update to our new preempt-rt
series.

   - port forward to 2.6.29-rc8
   - disable -rt conflicting config options
   - hotplug cpu fixes (peterz)
   - slab/pagealloc lock breaks (peterz / tglx) 
   - sigqueue caching for -rt tasks
   - posixtimer thread avoid useless wakeups
   - various build fixes (mingo, frank ....)
   - lots of tracer updates from -tip (check the tip git logs)

The outstanding improvement is the slab/pagealloc change which breaks
and splits locking and brought down worst case latencies in
problematic use cases from >500us to <100us.

As a side note:

   There seems to be a wide spread underestimation of the problem spots
   exposed by preempt-rt. The usual shrug off answer is:

	"I don't care about -rt. Come back if you can expose the same
	problem in the mainline kernel."

   This is a fundamentally wrong answer.

   	preempt-rt mostly exposes existing latency spots and magnifies
   	them

	Reducing latencies in -rt by a factor 5 will be not that
	prominent in a non-rt setup, but the problematic code area
	will still produce measureable latency problems.

   I'm well aware of the tradeoff between determinitic behaviour and
   throughput, but problematic spots (e.g. lock contentions) hurt
   both.

   So can we please put down the stupid "I don't care about -rt"
   attitudes and accept that we have to think about the mutual
   benefits of deterministic and throughput aspects without hurting
   each other ?

Do you have a time estimate for -rt2/ARM support, and is there
anything that can be done to help (testing, etc).

We are pleased to announce the next update to our new preempt-rt
series.

     - resurrected ARM and PowerPC support
     - tracing fixes for ARM (Uwe Kleine-Koenig)

The support for ARM/PowerPC has only been lightly tested. It might
crash and burn your system, make your hair curl, frigthen your cat and
give you sleepless nights. You have been warned !

On PowerPC watch out for the following warning:

   __do_IRQ called for irq X. PREEMPT_RT will crash your system soon.

__do_IRQ is deprecated and -rt does not support it anymore. Most of
the PowerPC subarchitectures do not longer use it, but you might be
unlucky and hit one of the remaining users. RT will spit out the
message above and then do what it said. :)

Download locations:

    http://rt.et.redhat.com/download/
    http://www.kernel.org/pub/linux/kernel/projects/rt/

Information on the RT patch can be found at:

    http://rt.wiki.kernel.org/index.php/Main_Page

Time estimate is about: now minus 20sec :)

Yup, the patches need full testing.

I have locally fixed by adding an include just above the cpumask_t

right,.. :-)

you got it right :-) The full fix (the bug also affects sparc) is 
already queued up - see it below.

Subject: [PATCH] numa, cpumask: move numa_node_id default implementation to topology.h, fix

Impact: build fix for powerpc and sparc

Today's linux-next build (powerpc allyesconfig) failed like this:

> In file included from include/linux/mmzone.h:776,
>                  from include/linux/gfp.h:5,

> arch/powerpc/include/asm/mmzone.h:32: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'numa_cpumask_lookup_table'

Caused by commit 082edb7bf443eb8eda15b482d16ad9dd8137ad24 ("numa,
cpumask: move numa_node_id default implementation to topology.h") from
the cpus4096 tree which removed the include of linux/topology.h from
linux/mmzone.h.

Same for sparc64 defconfig.

Hi,

It doesn't seem to be available (404).
But I can see a 2.6.29-rc8-rt4.bz2 downloadable.

Thanks.

This is a channel log from #linux-rt

19:57 < clark|w> tglx, just how small was the -rt3 window (which I hit btw)?
19:58 < tglx> you mean how long -rt3 was up on the web ?
19:58 < clark|w> yeah
19:58 < tglx> half an hour or so
19:59 < clark|w> because I got it, built/booted it (64-bit) and was running it 
                 up til thismorning when I saw that you'd released -rt4 :)
19:59 < tglx> 64bit was fine
19:59 < tglx> I fixed a 32bit PAE bug in -rt2 and when I pushed out -rt3 I did 
              not notice that half of the fix was lost
20:00 < tglx> so I zapped it and pushed out rt4
20:00 < clark|w> cool
20:00 < clark|w> good think I'm 64bit clean :)
20:00 < tglx> but I was too tired to send out another mail

Just FYI
Uwe

Hi,

I understood statement that Thosmas explained about invalid access of
2.6.29-rt1 soruces.
In general,
We remeber rc directory (./v2.6/testing/ and release directory
(./v2.6/) certainly.

Release Version is located in http://www.kernel.org/pub/linux/kernel/v2.6/ site.
RC      Version is located in
http://www.kernel.org/pub/linux/kernel/v2.6/testing/ site.

I summarized quick howto per notice of "2.6.* rt patch" file.
fc9#> wget http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.29.tar.bz2

Hi,

I understood statement that Thosmas explained about invalid access of
2.6.29-rt1 soruces.
In general,
We remeber rc directory (./v2.6/testing/ and release directory
(./v2.6/) certainly.

Release Version is located in http://www.kernel.org/pub/linux/kernel/v2.6/ site.
RC      Version is located in
http://www.kernel.org/pub/linux/kernel/v2.6/testing/ site.

I summarized quick howto per notice of "2.6.* rt patch" file.
fc9#> wget http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.29.tar.bz2
  (If linux version is RC[release candidate] version,
 use "wget http://www.kernel.org/pub/linux/kernel/v2.6/testing/***" command.)

We are pleased to announce the next update to our new preempt-rt
series.
 
      - fix a fork/exit bug in the signal per task cache (/me puts on
        a huge brown paper bag - Thanks to Phillipe Reynes and Will
        Schmidt for reporting and testing)

      - fix a group scheduling migration accounting bug (decoded with
        and fixed by Peter Zijlstra - reported by Robin Gareus)

      - tlb gather rework by Peter Zijlstra - Thanks Peter !

      - the usual fixlets

The tlb rework might be incomplete on some of the uncountable
incarnations of PowerPC and ARM platforms, so look out for wreckage
and keep the usual tools (fire-extinguishers, brooms, buckets etc.)
handy.

Download locations:

    http://rt.et.redhat.com/download/
    http://www.kernel.org/pub/linux/kernel/projects/rt/
 
Information on the RT patch can be found at:

    http://rt.wiki.kernel.org/index.php/Main_Page

to build the 2.6.29-rt2 tree, the following patches should be
applied:

    http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.29.tar.bz2
    http://www.kernel.org/pub/linux/kernel/projects/rt/patch-2.6.29-rt2.bz2

The broken out patches are also available at the same download
locations.

Enjoy !

       tglx

I can confirm that the tlb rework does appear to be missing some parts
for Power.  (Using 2.6.29-rt3 on pseries ppc64)

arch/powerpc/kernel/built-in.o:(.toc1+0x4d0): undefined reference to
`per_cpu__ppc64_tlb_batch'
<...>
mm/built-in.o:(.toc1+0xed0): more undefined references to
`per_cpu__ppc64_tlb_batch' follow

Not clear to me if this is just missing a "DEFINE_PER_CPU_LOCKED" to
replace the removed "DEFINE_PER_CPU", (similar to the prior RT patches),
or if the tlb rework is more involved.   So, I will patiently remain
tuned in.  :-)

Thanks, 
-Will

No, the DEFINE_PER_CPU was removed accidentaly. Should have stayed there

Thanks for cc'ing me...

Just a heads up. I'm still having shutdown/suspend problems with this
release as before (I had not reported the suspend problem, I think -
machine hangs and has to be power cycled). Booting with "noreplace-smp"
fixes both. Is this something I could disable through configuration
options?

I was also seeing a hard hang when running a java program (with the
Fedora 10 open source java) - the swingosc gui component of
SuperCollider 3 (a computer music synthesis program). Impossible to know
what had failed, machine completely catatonic and nothing left on the
logs. 

I managed to start the same program _once_ (have not tested again) with
2.6.29.1/rt4 + some patches & config from fc10' koji 2.6.29.1-15. The
mouse seemed to pause a couple of times and then I killed the program.
Restarting it again was successful. Sorry to not have more hard info...

-- Fernando

No. I have this shutdown/suspend thing on my todo list. Can you send
me your .config please ? This happens with the stock -rt kernel or do
you have other patches on top of it ?

Ah, ok. No problem. If it were not for this feature I'd probably release
a test version for Planet CCRMA. 

> Can you send me your .config please ? 

Attached. 

> This happens with the stock -rt kernel or do

Other patches on top of it. I'm building rpm packages merging the latest
Fedora .src.rpm's with rt (as I have been doing for a long long time). I
have to have as close a kernel as possible to the Fedora kernels
(drivers + configs, within reason - some of the stuff does not patch
cleanly of course[*]). The kernel I'm testing is merged with
2.6.29.1-15 / fc10. 

Sigh, I know, I know, I have to try to test with the vanilla tree. I
don't anticipate having time to do that soon (concert tomorrow, trip
starting next week).

You __have__ one?? Wow. Anyway, it seems that the java problem is gone
or something else killed it (another software upgrade perhaps?). Which
is good. 

Thanks again, looking forward to the next release!

[*] over the years I have tried different approaches and this is the one
that has given me kernels that work and are most compatible with the
rest of Fedora.

Dear Thomas,
>
>The broken out patches are also available at the same download
>locations.
>
>Enjoy !

Thank you for new release announce.
I am using new version ( linux-2.6.29.1-rt4 ) now .
config file is http://leemgs1.googlecode.com/files/i386.2.6.29.1-rt4.ftrace.config.20090404

I have one question. What is "broken-out" 's meaning  for rt patch file?

When I opened  realtime patch  files for vanilla kernel,
I always checked 2 files like belows.
http://www.kernel.org/pub/linux/kernel/projects/rt/patch-2.6.29.1-rt4-broken-out.tar.bz2
<-- collection of seperate files for each patch.
http://www.kernel.org/pub/linux/kernel/projects/rt/patch-2.6.29.1-rt4.bz2
<-- only one patch file.

What is difference  meaning of file-name format
between "patch-2.6.29.1-rt4-broken-out.tar.bz2" and "patch-2.6.29.1-rt4.bz2" ?	
I have always wondered that.
I am sorry for sending this stupid and easy question.

Thanks,
GeunSik Lim,

GeunSik,

The broken out tar ball contains a patch series of smaller patches,
which need to be applied in a give order. The order is determined from
the series file. It's a "quilt" series. quilt is a patch series
management tool. "man script" 

We keep those smaller patches for various reasons:

- It's way easier to move forward to the next kernel version with
  smaller patches than with a huge all in one patch.

- It's easier to split out functionality from the patches and rework
  that particular issue and replace the patches in the series

The broken out series is provided for people who want to look into the
details of the patches and for preempt-rt developers.

patch-2.6.X-rtY.bz2 is the combination of all patches from the series
applied. We provide this as a conveniance for users and testers so
they just have to apply one big patch.

Thanks,

	tglx

Happens this shutdown/suspend problem every time or is this sporadic ?

For me it is repeatable (on both a laptop and a desktop machine so it
does not appear to be very hardware specific). It might be of course an
interaction with the Fedora patches I use. 

In the category of "I wish I had a crystal ball" reports with no hard
data, I can confirm that my build of rt4 does hang. I was trying
2.6.29.1-rt4 during a rehearsal for a concert yesterday[*] and after a
hard hang I reverted to the vanilla Fedora kernel (which is what I had
been using because of that problem - no clues left behind in logs).

Hmm. Can you upload your full patch queue and the binary rpm so I can
give it a test ride ?

Sure, no problem. I just did a release to planetcore-testing repo (with
a warning to the planetccrma list), you can find it here:

http://ccrma.stanford.edu/planetccrma/mirror/fedora/linux/planetcore/testing/10/i386/repoview/index.html
http://ccrma.stanford.edu/planetccrma/mirror/fedora/linux/planetcore/testing/10/x86_64/repoview/index.html

(the one I have tested and hangs is the i386 PAE version)
Source here:

http://ccrma.stanford.edu/planetccrma/mirror/fedora/linux/planetcore/testing/10/SRPMS/

(if you don't want to figure out the .src.rpm - I would not blame you -
I can give you a list of the patches that were actually applied - of the
ones that are included in the package)

No problem. I know how to distangle those beasts.

Still I have no reproducer yet. One of my 32bit test machines survived
a 200 cycle test w/o showing it.

Is there anything special what you run, load ... ?

Looks like I need to add a 32bit install to my T61 in the hope to
reproduce.

Thanks,

Arghh, I don't know what it could be then. You mean 200 power cycles??
Wow... it only takes one here. Thanks for testing. 

> Is there anything special what you run, load ... ?

Not that I can think of right now. This happens on 32 bit installs on
both Fedora 9 and Fedora 10. Nothing special installed, of course I have
the Planet CCRMA packages but they don't involve additional kernel
modules or anything that (I think) deals with startup or shutdown. 

> Looks like I need to add a 32bit install to my T61 in the hope to

Sorry for the inconvenience. Additional installs, argh (BTW, I won't be
reading email for at least a week, of to LAC2009 tomorrow with a week of
R&R before - please keep cc'ing me on rt stuff). 

Thanks!!!

Does it trigger when you just boot up and the immediately shut down
w/o doing any work on it ?

Could you try whether the following triggers the bug as well: Boot up,
do work or whatever. Make sure your data is sycned to disk. :)

# echo 0 >/sys/devices/system/cpu/cpu1/online

If that does not trigger, then check whether it survives the
shutdown/reboot. If it does we look further.

Can you provide the list of modules loaded ?

Starts and closes fine here with my system. Also has not made my mouse
slow, yet. However, neither ndiswrapper 1.53 nor 1.54 does compile with
this kernel.

Yes. Just tried again. Clarification: triggers on a "halt -p", _not_ on
a reboot.

It triggers it immediately (in my laptop), I tried from a text console
and it spews things and at the bottom a poke_text thing like before
(after a while I got a couple of messages from iwl3945 about a timeout
and somehow it started to reboot, either when I pressed the power button
or when I did <ctrl><alt><del>)

Three lists attached, first all modules after I login, then modules
after a single user boot and then two more after I removed bluetooth and
80211* modules on a hunch, fails to power off in all cases (I first saw
a ref to blue something at the very top of the dump, so removed that,
then saw a reference to 80211 at the top, removed that, then I gave
up :-)

We are pleased to announce the next update to our new preempt-rt
series.

 	- include the futex rework + requeue_pi support (Darren Hart)

The futex changes need profound testing. As we know from prior futex
work the best stress tests for the futex interface are RT-Java-VMs
especially with enterprise work loads on larger machines. Can the
folks who have access to such monstrosities please unleash the beasts
and give the futex code a good work out ? Please tell your sysadmin
upfront that he should be stand by to fix up the resulting wreckage
which might vary from harmless to system replacement.

Unfortunately I was not able to track down the weird 32bit PAE
shutdown crash, so the affected users need to stick to the
nosmp-alternatives work around for now.

Information on the RT patch can be found at:

     http://rt.wiki.kernel.org/index.php/Main_Page

to build the 2.6.29.1-rt5 tree, the following patches should be
applied:

     http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.29.1.tar.bz2
     http://www.kernel.org/pub/linux/kernel/projects/rt/patch-2.6.29.1-rt5.bz2

The broken out patches are also available at the same download
locations.

Enjoy !

Dear Thomas

Thank you for your notice about new rt patch.
I am running linux-2.6.29.1-rt6  on Q9300 with fedora 9 distribution
normally like belows. So I changed version from linux-2.6.29-rt2 to
linux-2.6.29.1-rt6.
I will test about  a various case with linux-2.6.29.1-rt6 version.

when using patch-2.6.29.1-rt8 with CONFIG_PREEMPT_SOFTIRQS=y, but not
enable PREEMPT_RT, there will be an error when linking kernel:

undefined reference to hrtimer_wait_for_timer

I found that, hrtimer_wait_for_timer is only defined when PREEMPT_RT is
enabled, but in include/linux/hrtimer.h, the source code is like this:

#ifdef CONFIG_PREEMPT_SOFTIRQS
 extern void hrtimer_wait_for_timer(const struct hrtimer *timer);
#else
# define hrtimer_wait_for_timer(timer) do { cpu_relax(); } while (0)

a possible fix should be:

diff --git a/include/linux/hrtimer.h b/include/linux/hrtimer.h
index 8bafa35..1c1cdf3 100644
--- a/include/linux/hrtimer.h
+++ b/include/linux/hrtimer.h
@@ -366,7 +366,7 @@ static inline int hrtimer_restart(struct hrtimer
*timer)
 }
 
 /* Softirq preemption could deadlock timer removal */

Darn. the patch is halfways right. the #ifdef needs to be only around
the if() line. Otherwise your /proc/loadavg values will never be
updated. I'll push out -rt13 with the proper fix..

Thank you for notice of 2.6.29.r-rt16 release.

This is a report  about "/proc/interrupts" result in my development system.

* System requirements :
  Core2 Quad Q6600 , LV-676 Motherboard , SATA 160G, DDR2 3G ,
  ftp://ftp.commell.com.tw/COMMELL/support/LV-676/BIOS/676x161.zip.

In summary, I can't get irq loadbalancing(/proc/interrupts) in my system using
2.6.29.4-rt16 linux kernel because of LV-676 motherboard's  H/W problem.
( I disabled [ ]irqbalance - userspace with "ntsysv" command in this
experiment . )

So, I asked Commell company about this problems.
For reference, Belows is answer from their technical service team.

-- [ From tech@commell.com.tw] ---------------------------------------------
Hi
Sorry for keep you waiting.
We had setn LV-676 motherboard to BIOS vendor for solution,
still now no resond yet, any respond will pass to you.

We had constantly push for solution, and BIOS vendor is working on this
issue and attempt to solve this problem,
any message from them will let you know.

K.H. Ooi
------------------------------------------------------------------------------------

Currently, I am using "smp_affinity" in this LV-676 mother board like belows.

          Binary Hex
    CPU 0 0001 1
    CPU 1 0010 2
    CPU 2 0100 4
    CPU 3 1000 8

[geunsik@centos5.3 ~]$
[geunsik@centos5.3 ~]$  echo 8 > /proc/irq/18/smp_affinity
[geunsik@centos5.3 ~]$  for i in `ls -1 /proc/irq/*/smp_affinity`; do
echo "smp affinity CPU3 +++ $i"; echo 8 > $i; done  <--  assign  irq
to CPU3
[geunsik@centos5.3 ~]$ cat /proc/interrupts <---check irq-balancing

* Don't use irq affinity about timer irq
[geunsik@centos5.3 ~]$  echo 8 > /proc/irq/0/smp_affinity
  -bash: echo: write error: Input/output error

We are pleased to announce the next update to our new preempt-rt
series.
 
     - tracing updates (Luis)
     - latency histograms (Carsten)
     - build warning fixes (Clark)

2.6.29.4-rt17 is the last major update to the 2.6.29 -rt series. 

There will be bugfix releases as necessary and eventually an extra
update release once the real hwlat (former SMIdetector) module / tool
is published by JCM aka. Jon "slaCker" Masters.

In the meantime I'm moving on to 30-rt.

     - hwlat latency detector module (Jon Cool Masters)

I have to say it works pretty well when you call someone a Slacker :)

Clark is working on user space tools which help you to use it w/o
fiddling module parameters. It's going to be in the next rt-tests
release which has a not yet defined schedule. I wonder whether I
should try that slacker trick again :)

We are pleased to announce the next update to our new preempt-rt
series.

   - update to 2.6.29.5 (2.6.29.5-rt20, which I uploaded yesterday but
     did not announce due to the findings below)

   - softirq: lower default priority below hardirq default priority

This fixes a long standing default priority configuration problem of
the -rt series. On UP machines this can result in net_tx softirq
running in an endless loop and starving the irq threads and the other
softirq threads and of course everything with lower priority. It might
be possible to happen on a SMP machine when the hardirq thread
affinities are tweaked in the right way.

What happens is:

     tx interrupt
        lock(card->tx_lock);
        dev_kfree_skb_any(skb);
          blocks on a contended lock

     net_tx softirq runs
        unlocks contended lock but does not schedule away due to equal prio
	repeat:
         calls xmit
	 try_lock(card->tx_lock) fails
	   -> reschedule skb which keeps net_tx running
         goto repeat;

The scheduler does not schedule away net_tx, so this goes on forever.

This has been there forever, but it seems to be easier to trigger in
the 29 -rt series which is probably due to the slab cache lock breaks
we did.

The problem is restricted to a dozen of wireless adapters and network
cards where e1000e is the most popular one. We could patch the
affected drivers for -rt, but we need to have a closer look at the
general assumptions of drivers vs. hardirq/softirq. Note, this is not
a mainline problem as the semantics are entirely correct there.

Lowering the priorities of the softirq threads below the hardirq
threads priorities is a safe workaround for now. It prevents the
runaway scenario under all circumstances as it resembles the mainline
semantics closely.

For all existing -rt systems the problem can be solved w/o patching
the kernel by adjusting the priority of the softirq threads from the
init scripts with chrt.

It's extremly hard to trigger this, we never had a report of that
before, and I want to say thanks to Bernd Oelker who meticulously
worked on reproducing the problem and debugging it with all evil
methods and patches I could come up with. And no, I'm not going to
tell you which nasty hacks made it possible to decode this :)

We are pleased to announce the next update to our new preempt-rt
series.

    - fix the network live lock issue for real

    - disable preemption across iomap atomic section

    - indentify false positives in the softirq pending check
      in the nohz code.

The network issue which I described in the -21 release still persists
between net-rx and net-tx softirqs. The real fix is replacing the
spin_trylock with spin_lock in the affected drivers.

On -rt we had several unexplained reports of cpus going idle with a
pending softirq. I got hands on a trace of such a situation. What
happens is that a softirq is blocked on a lock which is held by a task
which is either blocked itself or running on another CPU. When there
is no other active task on the CPU then it goes idle but the softirq
pending bit of the blocked softirq thread is still set. This leads to
false positive warnings. To filter out those cases the blocked state
of the softirq needs to be checked instead of printing the warning
blindly.

I'm getting slightly weird behavior from rt23 in an intel quad core
machine (my T61 laptop is fine), rt22 was fine. It is some timer issue,
if I type continuously I get (every few seconds) repeated keys. Nothing
in the logs, nothing in dmesg that is (significantly) different from an
rt22 boot.

One of my users has been hitting an issue with suspend, the machine
suspends but will not come back alive. 

Below is the latest debug info he sent me (the issue still happens with
rt23, got a report this morning)

Amazingly enough, I was finally able to get some information logged by
following some of the steps in basic-pm-debugging.txt.  This
accomplished by doing "echo 1 > /sys/power/pm_trace; echo core
> /sys/power/pm_test; echo mem > /sys/power/state."  Some of the other
test modes also created the exact same log message.  Here it is with
some context:

Hmm. The only change which touches timer related stuff is the ktime*
speedups. Can you please apply the revert patch below and check
whether that changes anything? If not, then we need to look at the
2.6.29.5 -> .6 delta.

Thanks,

The bad behavior is gone with the patch reverted. 

But life is not so simple :-) 

I rebooted into the newer kernel and the problem was gone. Then I
rebooted into the older (unreverted) kernel and the problem was not
there either! Sigh. Then I powered down the machine, powered up in the
older kernel and the problem was there. Powered down, powered up in the
newer kernel and the problem was gone. Warm boot into the older kernel
and the problem is _not_ there. So it would seem there's something
getting screwed up at the hardware level that the reverted patch
"fixes"...

When the problem happens it is very obvious. And also affects the
screensaver, of course. I don't see it in my laptop and on another P4
based machine running fc11 (as opposed to fc10 in the others) and a
different build. 

Thanks!

We are pleased to announce the next update to our new preempt-rt
series.

    - update to 2.6.31-rc4

This is a major rework of the rt patch series. Thanks to Clark
Williams and John Kacur for providing the merge to 2.6.30 while I was
stabilizing .29-rt. While the 30-rt series looked quite stable, we
decided to skip 30-rt entirely to keep track with the ongoing mainline
development for various reaons. The .31-rt series is planned to be
stabilized as we have done with .29-rt.

The main changes in this release are:

- interrupt threading

    interrupt threading is now a pure extension of the mainline
    threaded interrupt infrastructure. This reduced the patch size of
    the forced irq threading to mere

      8 files changed, 178 insertions(+), 13 deletions(-)

    Another interesting detail is that the new forced threaded code
    uses per device threads instead of per interrupt line threads as
    we have done in the past. This was just a logical consequence of
    the per device thread (voluntary threading) infrastructure in
    mainline and allows us now to share an interrupt line between a
    hardirq based handler and a threaded handler device. One use case
    which comes to my mind is AT91 which shares the timer and the
    serial port interrupt; we now can solve that problem w/o nasty
    hacks by requesting a threaded handler for the serial port which
    shuts up the serial device interrupt in the hard interrupt handler
    part.

- rework of the locking infrastructure

   Up to now the -rt patches changed the raw_spinlock_t to
   __raw_spinlock_t and added another two levels of underscores to
   many of the locking primitives. A compiler trick was used to chose
   the implementation for RT=y and RT=n compiles depending on the lock
   type in the lock definition.

   This is nasty as there is no destinction in the source code which
   kind of lock we are dealing with except if one looks up the lock
   definition/declaration. It definitely was a clever move in the
   first place to get things going, but aside of the underscore
   conflicts which were introduced by lockdep it was not longer
   acceptable to hide the fact that we are treating a lock
   differently. Same applies for the changes to (rw_)semaphores which
   used the compat_ trick for those ownerless anonymous semaphores
   which are taken in one context and released in another.

   The annotation of the code which uses those special treated locks
   has been long discussed and one of the proposed solutions was to
   change all spinlocks which are converted by -rt to sleeping
   spinlocks from spinlock_t to lock_t and have another set of
   lock/unlock/trylock functions for those. That is definitely the
   _preferred_ solution, but it's a massive and horribly intrusive
   change. Steven was working on it for some time, but it simply does
   not scale IMNSHO.

   I went the other way round. In -RT we have identified the locks
   which can _not_ be converted to sleeping locks and so I went there
   and converted them to atomic_spinlock_t and created a set of
   functions for them. I converted the already known locks to that
   type and fixed up all the functions (s/spin_*/atomic_spin_*/) which
   annotates the code and makes it clear what we are dealing with.

   [ I admit "atomic_spinlock_t" is a horrible name, but it's the best
     I came up with so far. If you have a better idea please feel free
     to add it to 

         http://rt.wiki.kernel.org/index.php/Atomic_Spinlock

     instead of starting a bikeshed painting thread on the mailing
     lists about that name. Once we have something better it's just a
     sed script to fix it. ]

   For !RT the spin_* functions are mapped to atomic_spin_* via inline
   functions which do the type conversion. That has another nice side
   effect: some places in the kernel (mostly scheduler) use
   _raw_spin_* functions on locks to avoid the lockdep invocation in
   some places. With the type conversion a lock needs to be defined
   atomic_spinlock_t (or raw_spinlock_t) to have access to that
   _raw_spin_* functions. Using e.g. _raw_spin_lock() on a lock
   defined with spinlock_t/DEFINE_SPINLOCK will cause a compiler
   warning. I think that's a Good Thing.

   On RT the spin_* functions are mapped to the corresponding rt_lock
   functions with inlines as well. Very simple and much more
   understandable than the nifty PICK_OP magic with the underscore
   convolution. :)

   I did the same conversion for all (rw_)semaphores which are known
   from -rt to be ownerless anonymous semaphores; i.e. taken in one
   context and released in another. We renamed them to
   compat_(rw_)semaphores up to now and let the compiler pick the
   right function. Again here I went down the road and annotated the
   code for those with newly created anon_* and [read|write]_anon_*
   functions. In !RT the non annotated ones map to the anon_ functions
   and on RT we map them to the corresponging rt_* ones. This
   annotation should also be helpful to cover at least the non
   anonymous (rw_)semaphores via lockdep.

   Part of that semaphore rework is the RFC patch series I posted
   recently to get rid of the init_MUTEX[_LOCKED] irritation (minus
   the ones which turned out to be wrong)

   The spinlock and semaphore annotation work is separate now and can
   be found in the rt/atomic-lock and rt/semaphore branches of the
   -tip git repository, which leads me to the next important point:

- start of gitification

   While reworking all of the above I went through the quilt queue and
   sorted out patches into different rt/ branches. If you clone the
   -tip git tree you'll find a bunch of branches starting with rt/.
   They contain various independent changes which are all part of the
   -rt patch. The combination of those branches can be found in the
   rt/base branch.

   I still have a leftover of ~140 patches (roughly 40% of the -rt
   queue) which I committed into the rt/rt-2.6.31-rc4 branch just as
   is simply because I ran out of time. My annual summer vacation
   (helping my wife to run the kitchen in the church community kids
   summer camp) is starting on friday.

   While the other rt/ branches are mostly bisectable the final one is
   not yet there. I restructured the patch queue in a logical way, but
   there is more work to be done to clean it up. So expect it to be
   replaced.

Further plans:

   1) We seriously want to tackle the elimination of the PREEMPT_RT
   annoyance #1, aka BKL. The Big Kernel Lock is still used in ~330
   files all across the kernel. A lot of work has been done already to
   push down the lock into the code which still thinks it needs to be
   protected by it. Some work has been done already in the (a little
   bit stale) kill-the-BKL and core/kill-the-BKL branches of the -tip
   git tree. If you want to help, please check those branches whether
   the code has been tackled already or not to avoid redundant
   work. If you decide to take care of one please note it on:

       http://rt.wiki.kernel.org/index.php/Big_Kernel_Lock

   2) I'm going on vacation for 10 days. Please send patches and
   bugreports^Wsuccess stories to the mailinglist as usual. There are
   folks looking out.

Enough said. Get the code and have fun!

this change breaks the compilation of the binary nvidia kernel module.
in order to build the module, i need to apply the attached patch.
