Well..  order-1 GFP_ATOMIC allocations are unreliable.  The networking
code should hanlde the situation and recover.  I assume that is
happening in this case?

Perhaps we did something in that code after 2.6.29 which increased the
frequency of the order-1 allocation attempts?  Maybe earlier kernels
used order-0 all the time?  Those are much more reliable.

Yes, the driver has recovered in all cases so far.

I think something happened to change the allocation as I never saw these O(1)
failures before with these particular drivers. I put in a few test printk's and
the buffers were 700-800 bytes long, and I would not expect them to require more
than an O(0) allocation.

I pushed 2.6.30-rc6 hard for ~12 hours without any recurrence of the problem.
Given the relative infrequency of the error, this certainly does not indicate a
fix in recent code. I will be trying to force it again.

I wonder if this is related:

http://bugzilla.kernel.org/show_bug.cgi?id=13069

Both point to post 2.6.29... Hmm.

I have been unable to repeat the problem with recent kernels - I am now running
2.6.30-rc6. This regression should probably be dropped even though it may show
up when 2.6.30 is released.

This bug is extremely difficult to pin down. I cannot reproduce it at
will. The system has to be up for a long time, which is difficult with
testing the late RC's of 2.6.30 and the code in wireless-testing so
that new bugs don't end up in 2.6.31-RCX. That said, it still was in
2.6.30-RC6 and I'm not aware of any changes since that would fix it.

My operating kernel is patched with additional diagnostics to help me
understand why a kmalloc request for a buffer of 1390 bytes suddenly
ends up as an O(1) request. Unfortunately, I don't have any answers.

Looking at the out-of-memory trace, there's still memory available but
the pskb_expand_head() allocation is GFP_ATOMIC so there's not much
the page allocator can do here. The amount of memory consumed by
inactive_file is pretty high so maybe the problem is related to the
recent mm/vmscan.c changes. Lets copy some more mm developers and see
if they can help out.

That is a very strange trace.  The Mem-Info indicates
that the system has more than enough memory free, and
also enough memory in higher-order free blocks.

This would indicate a bug somewhere in the page
allocator - this memory should have been given to this
allocation request.

I'm happy to see some action on this problem. As usual, I'm happy to
test patches and/or provide diagnostic output.

One question. 

Did your system fragmented in same way as to this
(see DMA32, 10052 of order-0 pages) in older kernel ? I think you can check
fragmentation status via /proc/buddyinfo.
=
kernel: Node 0 DMA: 3*4kB 3*8kB 5*16kB 2*32kB 4*64kB 1*128kB 2*256kB 0*512kB
1*1024kB 0*2048kB 0*4096kB = 2100kB
kernel: Node 0 DMA32: 10062*4kB 1*8kB 1*16kB 0*32kB 1*64kB 1*128kB 0*256kB
1*512kB 0*1024kB 0*2048kB 0*4096kB = 40976kB

Nothing like a party on Monday morning to get the week started!

What we appear to have is

o Allocation failure is high-order, high-priority, compound and atomic.
o swap is mostly unused, but we cannot enter direct reclaim.
o ZONE_DMA32 can be used
o The allocation path is in the slub allocator
o Are way above the order-0 watermarks so kswapd is probably not awake
o The minimum watermark for an order-0 page was about 647 pages in ZONE_DMA32
o The minimum watermark for an order-1 page was about 323 pages in ZONE_DMA32
o There are 10244 pages free at the time of the failure
o With the order-0 pages taken out for watermark calculation, there are
  182 free pages which is below the watermark of 323 pages for an
  order-1 allocation

While there is enough free memory overall, the zone watermark calculation
takes into account the order of the request. As this is an order-1 allocation,
the free order-0 pages are taken out of consideration and so the allocation
fails.

We've encountered this before and the conclusion was that the current
adjustments for watermark calculations of high-order allocations is right,
or at least there is no better alternative. In other words, the page
allocator in this instance is behaving as expected. Do we want to
revisit that discussion as to whether the watermark calculations for
high-order allocation should change? I think we'll reach the same
conclusion or at least decide that allowing the order-1 atomic
allocation to succeed here would just postpone the problem.

So the question is why are we doing a high-order atomic allocation in
this path? According to an earlier discussion on this problemn

So, SLUB is deciding to use order-1 pages for the slab allocation.
Ordinarily, it'll get away with that because order-1 pages will be
allocated from a path that can direct reclaim. However, if a slab is
being used for atomic allocations, there is a chance that it's the
atomic request that allocates a new page for the slab.

Larry, can you post the contents of /proc/slabinfo so we can see
what size pages are being used for the kmalloc() buckets please?

Larry, you say the buffer is 700-800 bytes. Can you confirm that 800 bytes
is roughly the request size being made by ieee80211_skb_resize()?

Pekka, assuming the request size is 800 bytes, and SLUB is using order-1
pages for allocations of that size, what happened order-1 allocations
falling back to order-0 allocations as necessary. That logic exists,
right? If so, could it be broken?

That logic is in allocate_slab() and if the higher order allocation
fails, we fall-back to struct kmem_cache ->min order. That in turn is
set up in calculate_sizes() to get_order(size) so it seems pretty
unlikely to me the allocation is 800 bytes. Of course, I could be
missing something here and there's a bug in oo_make() or oo_order().
Hmm.

Is there any chance you could hatchet together a patch
slab-allocation-failure that reports on slab allocation failures similar
to what the page allocator does? Minimally, it should tell us what
the size of the allocation was but any other information such as the
same of the slab, the size of pages it normally uses are, etc. would
also be useful.

It would not just postpone the problem, it would also
bring the system closer to a state where kswapd does
something about the order-1 free areas.

This might postpone the problem indefinately.

Currently the system fails early, without kswapd
kicking in and freeing new order-1 areas.

The system is not generating the failures at the moment, but here is

For some of the failures, the size was in the 700-800 range, but the
ones I found in my logs called pskb_expand_head() with skb->data_len
of 1962. For those calls, head_need and tail_need were both 0.

How do you figure it does not just postpone the problem? If there are a batch
of order-1 allocations that come in like this, it will eventually deplete
the higher-order pages and then fail because kswapd is not getting woken up.

Minimally, if we were to ignore the watermarks, there would need to be logic
that says

	"If a high-order allocation would fail due to high-order watermarks
	not being met, but the watermarks are ok from an order-0 perspective
	and the high-order page is available, then grant the allocation but
	wake up kswapd as if the order-1 allocation had failed to get the
	high-order watermarks back in shape"

If the allocation was granted, then kswapd will still not kick in.

Would something like this be sufficient? Figuring out the actual _size_ 
passed to kmalloc() is pretty difficult as then we would need to do the 
NULL test in fastpath code or pass the argument deeper in the call-chain.

It's much better than nothing. In the event of an allocation failure, we'll
know which kmalloc bucket it's coming out of so we'll have a limited range
of possible buffer sizes.

I have some suggestions on what we're outputting though.

size could be almost anything here for a casual reader. You are
outputting the size of the object plus its metadata so the name should
reflect that. I think it would be better to output objsize= and the
object size without the metadata overhead. What do you think?

In addition, include how many objects there are per-slab and include what
the order is being passed to the page allocator when allocating new slabs.
Would that be enough to determine if fallback-to-smaller orders occured?

There is a per slab counter ORDER_FALLBACK that is increased for
allocations that required fallback.

The current system has not been up very long and does not show the
fragmentation:

finger@larrylap:~/wireless-testing> cat /proc/buddyinfo
Node 0, zone      DMA      4      5      4      2      4      1      2

    17     14     12    262

After I did a git pull and a kernel build with the sources on an
NFS-mounted volume, the fragmentation increased:

Node 0, zone      DMA      4      5      4      2      4      1      2

After a git pull and a kernel build on a second NFS-mounted tree:

Node 0, zone      DMA      4      5      4      2      4      1      2

So how about something like this then?

Well, if the slab_out_of_memory() is called, we already know the
higher order allocation failed _and_ the fallback allocation failed.
So yes, it would be enough.

Larry reported this stack trace:

kernel: git: page allocation failure. order:1, mode:0x4020
kernel: Pid: 3707, comm: git Not tainted 2.6.30-rc1-wl #115
kernel: Call Trace:
kernel:  [<ffffffff80292f84>] __alloc_pages_internal+0x43d/0x45d
kernel:  [<ffffffff802b2383>] alloc_pages_current+0xbe/0xc6
kernel:  [<ffffffff802b66a4>] new_slab+0xcf/0x28b

That's in the order fallback for new slab allocations; so this cache must 
have oo_order(s->min) of 1.

To diagnose whether its object size dictates a >0 slab order, you could 
enable CONFIG_SLUB_STATS (it's disabled in his .config) and check which 
/sys/kernel/slab/cache/order_fallback increased.  Once you have identified 
the cache, you can get this information via 
/sys/kernel/slab/cache/{objsize,order,size}.  I think this is what 
Christoph was getting at.

You could even boot with `slub_nomerge' to determine whether cache merging 
was the issue where the cache under consideration was unnecessarily merged 
with one that requires larger higher order minimums.

I don't quite understand how its necessary to print the partial lists for 
each node, they should be exhausted if we're allocating a new slab if the 
node doesn't matter (and can't in Larry's case, he only has one).

Yes, agreed which is why I said it's unlikely that the allocated size is
800 bytes or so.

Sure. Applying my diagnostic patch will probably shed some light on the
subject too.

It doesn't hurt either, does it? Yes, we expect the partial lists to be
exhausted but it's better to print that out just in case we have a bug
some day somewhere and that condition is not true. This is very
infrequent slow patch code here anyway.

I wasn't sure whether you were proposing the patch as an addition to slub 
or just to help with this issue.  I agree it would help in a hopefully 
ratelimited manner for general slab allocation failures and would have 
avoided some of the confusion for this issue from lack of diagnostics.

It will lead to false postiives since you can get a free to a full slab 
which moves it back to an allowed node's partial list before count_free() 
is printed.

I am proposing it as a generic addition to SLUB.

With the above patch installed, I pushed my system hard enough to get
the O(1) allocation failures. This time they were triggered with a
'make -j8' on the kernel. No, I don't have that many CPUs, but I
figured that the extra make jobs might stress memory. My kernel is
2.6.30-rc8 from the wireless-testing tree. Everything matches Linus's
tree except drivers/net/wireless/, which contains what is essentially
2.6.31 code.

The dmesg output starting with the first allocation failure is:

Aha, SLUB thinks the minimum order for 4096 is 1. I guess you have
CONFIG_SLUB_DEBUG enabled? If yes, something like to following should
help. Christoph, are you okay with this patch?

? Or is this a path that only happens for small allocations?

Much nicer. There is a clear division between the object size and the
size including the metadata. There is also now a good idea of what sort
of request it was, we know what cache it was so we can guess the size
passed to kmalloc() with reasonable accuracy.

That looks like it would generate easier-to-debug-with messages and to
not-expert-at-slub eye, it looks correct. Slap a changelog on it with an
example message and go with it.  It should make page allocation failures
messages that go through SLUB a lot easier to figure out.

Anything that's beyond PAGE_SIZE * 2 is passed straight to the page
allocator and the intent of this patch is to disable debugging for all
big caches like SLAB does.

He likely has CONFIG_SLUB_DEBUG_ON set which enables debugging and thus
needs more than the payload for metadata.

Yup. I suspect a lot of people who are doing _testing_ enable that. If
you're unhappy with my patch (the get_order one which shouldn't affect
that many caches anyway), any suggestions how to fix this up? It seems
that the wireless stack at least does quite a few kmalloc(4096)
allocations.

We can probably switch back to page allocator pass-through in the near
future (when Mel's patches are in) but we need a fix for -stable.

I think networking rounds up allocations, but it's not wireless per se.

The cause of these failures has been determined. The wireless
subsystem frequently requests buffers of size 4096, but when SLUB
debugging is enabled and the debug info is added, the request becomes
of order 1 and memory becomes fragmented.

A controversial "fix" in which SLUB debugging was disabled for
allocations where adding such debugging info would increase the order
was discussed and tried. With a quick look at the commit list for
Linus's tree, I don't see that such a patch is available, but I will
be corrected if I missed it.

Thanks for the update.

Hmm, isn't it suboptimal to use a slab allocator for allocations taking up an
entire page?  That's the case on some architectures and seems to be the root
cause of the issue at hand.

I'd disagree with disabling slub debugging by default for caches where 
oo_order(s->min) increases as the result of using it.  This particular 
page allocation failure is happening for, presumably, kmalloc-4096, and 
the system has 4K pages.  Disabling debugging for that cache (and any of 
its aliases) implicitly will lead to errors going undiagnosed as a result.

If the current behavior is not changed, I will be forced to disable
SLUB debugging, which will explicitly lead to errors that are
undiagnosed. It seems better to me to debug when you can, but turn off
debugging in cases like this.

You're buying debugging support at the cost of increased memory 
consumption when you enable CONFIG_SLUB_DEBUG_ON and that's causing the 
page allocation failures because of fragmentation.  To reduce the minimum 
order required for caches such as kmalloc-4096, you'd have to disable 
debugging for that particular cache.  It's my opinion that such a 
configuration should not be the default, however.

You could argue adding `slub_debug=-,kmalloc-4096' support from the 
command line, but CONFIG_SLUB_DEBUG_ON should not change its well-defined 
purpose of enabling debugging on all slab caches.  Otherwise the rest of 
us would be forced to add `slub_debug=,kmalloc-4096' for consistent 
behavior with older kernels.

Well, I obviously don't agree here because kmalloc-4096 debugging
causes problems in the real world. Furthermore, SLUB never supported
debugging for objects that big historically because of page allocator
passthrough. And with Mel Gorman's page allocator optimizations, we
might be going back to that.

So we should fix SLUB debugging as outlined by Mel Gorman and
Christoph Lameter. I simply haven't had the time to do it. Patches are
welcome!

I don't think CONFIG_SLUB_DEBUG_ON is generally the configuration used in 
the real world.

The option has a clear and well-defined purpose and that is to enable 
debugging on all slab caches.  If you modify its definition, users will 
generally ignore the warning about debugging being disabled when "the 
minimum possible order at which slab may be allocated is higher than 
without."  And unless they check the kernel log for such a warning to boot 
with `slab_debug=,kmalloc-4096', we lose testing coverage because we 
cannot enable redzoning or tracing after boot.

Even when page allocation is fast enough, it would still be helpful to 
configure slub to not do passthrough purely for the lightweight debugging 
opportunities.

You're referring to `slub_debug=A'?  I think CONFIG_SLUB_DEBUG_ON should 
continue to enable debugging on all slab caches and in instances where it 
causes page allocation failures such in Larry's case because 
oo_order(s->min) with debugging on is greater than oo_order(s->min) with 
debugging off, you can emit a friendly warning in your recently added 
slab_out_of_memory() about using `slab_debug=-,<cache>'.

We have a disagreement about which is the default behavior, but I would 
opt on the side of adding exemptions to a debug configuration option as 
opposed to requiring additional command line parameters to be fully 
enabled.

It is, hence the epic bug report that's eaten too many man hours
already! Look, we encourage _testers_ to turn all as much as debugging
options as possible so we catch bugs early. That why the only sane
defaults are the ones that don't cause other problems!

I don't know why you want to argue this. It's simply not an option to
say "stupid user, fix your config" in core code like the slab
allocator. Enabling CONFIG_SLUB_DEBUG_ON is a very reasonable thing to
do when you are a tester looking for bugs.

Yup, I was referring to slub_debug=A and no, I don't agree with you
that it should be on by default. Only people who know what they're
doing should enable the option and a random tester by definition
doesn't (no offence to Mr. Random Tester).

SLUB for some period of time had passthrough. It did not start out like
that though.

kmalloc-4096 causes problems in the long run and so do other caches that
are of similar size. But it allows debugging to occur. Silently switching
it off is something I am not comfortable with.

None taken.

For me, the next step is clear. As I'm much more interested in finding
bugs in the wireless system than in the mechanics of SLUB allocation,
I need to disable CONFIG_SLUB_DEBUG_ON. BTW, I use SLAB on Linus's
mainline tree and SLUB on the wireless testing tree. I build and boot
the mainline kernels mostly to look for quick failures/regressions,
but run the w-t kernels looking for longer-term effects such as memory
fragmentation or slow memory leaks.

For Rafael's benefit, we do need to decide if this is a bug or merely
an unintended side effect. My sense is the latter and Bug #13319
should have a summary of this discussion added to the record, and then
the bug should be closed.

I suggested adding a

Does that work for you?

I don't see how that's different from enabling debugging on all caches 
like CONFIG_SLAB_DEBUG_ON currently does and then warning at the time of 
slab allocation failure that it may be the result of the debugging 
metadata so the user can subsequently prevent it.  In other words, if we 
use MAX_DEBUG_SIZE as Pekka originally implemented as
(3 * sizeof(void *) + 2 * sizeof(struct track)), do this:

I feel that asking a user to add a command line parameter such as 
`slub_debug=A' in addition to CONFIG_SLUB_DEBUG_ON will likely lead to 
less testing coverage and bugs going unreported.  CONFIG_SLUB_DEBUG_ON is 
not something that a distro is going to enable or would be used in a 
production environment, it's something that's used to debug slub and/or 
slab allocations either during the development of new kernel code or when 
an underlying problem is realized.

Quite the contrary, I agree completely with the above, and that's why I'm 
arguing for full debugging to be enabled when a well-defined configuration 
option is enabled.  I simply don't believe that such debugging should be 
coupled with a command line option to be fully activated for all caches.

It may be easier to check the order of the initial size vs. the order of
the size with all metadata

Ah, right.  Then we could simply eliminate the check on s->flags to begin 
with.

This patch is supposing that `slab_debug=-,<cache>' actually disables all 
debugging for <cache> which would need to be implemented first, but I 
think this is a better alternative than requiring slab_debug=A for full 
debugging after enabling CONFIG_SLUB_DEBUG_ON.

We could add an option that disables debugging for troublesome page
size slabs


slab_debug=p

or so

I definitely like that more than slab_debug=A, where we're requiring an 
added parameter for full debugging to be activated.

I'm curious whether there would ever be any use for disabling debugging on 
specific caches for reasons other than higher minimum orders for metadata, 
though, given that we already support things like slub_debug=FZ,cache, 
which should only enable free debugging and redzoning even with 
CONFIG_SLUB_DEBUG_ON enabled for cache.

I think the solution to this is really based on good software engineering 
and test practices, though, so hopefully there'll be a consensus on which 
direction to take before any time is spent in implementing and pushing it.

One of the reasons for disabling debugging is to speed up the kernel. Race
conditions may vanish due to the additional latency added by the debugging
code. Ideally you know which slab cache has the race and you only would
enable it on that one.

Lets go with the slab_out_of_memory() patch you outlined in a previous
post and implement the slub_debug=p thing Christoph suggested. I think
it's the best compromise at this point. When you guys finally see the
light, we can always change it to a reasonable default. ;)

So can you send a patch, please?

Sure, let me know if you think this is -rc material; otherwise, the bug 
will have to be deferred until 2.6.32 with the temporary workaround of 
disabling CONFIG_SLUB_DEBUG_ON.

We're at -rc2 so yes, I do think we should fix 2.6.31.

http://patchwork.kernel.org/patch/34385 should fix your issue (try with 
CONFIG_SLUB_DEBUG_ON still enabled and slub_debug=O on the command line).

Pekka indicated he wanted this fixed in 2.6.31, so he'll probably push it 
to Linus before the 2.6.31-rc3.

Yup, if it's not too much trouble Larry, I'd appreciate if you gave it
a spin before I apply the sucker. Note to regression trackers, I don't
think this should go to -stable because it depends on other patches in
mainline and there's an obvious workaround for the problem (disable
CONFIG_SLUB_DEBUG_ON). Furthermore, it's very unlikely people will hit
this on production configurations anyway.

Pekka,

I have been running the patch for ~24 hours with slub_debug=0 as a
boot option. So far, no problems. My workload has not involved as many
network operations as some times, but my memory has not fragmented.
The output of 'cat /proc/buddyinfo' is as follows:

Node 0, zone      DMA      8      5      5      4      5      5      5
     4      3      0      1
Node 0, zone    DMA32   1804   1585   3007     36      0      0      0
     0      1      0      0

As might be expected, the high-order fragments are gone, but the O(1)
pieces have not been depleted.

This bug was fixed by commit 781b2ba6eb5f22440afac9c79a89ebd6e3674a60
entitled "SLUB: Out-of-memory diagnostics" by Pekka Enberg
<penberg-bbCR+/B0CizivPeTLB3BmA@public.gmane.org> and dated Wed Jun 10 18:50:32 2009 +0300.

The fault occurred because when CONFIG_SLUB_DEBUG was set, many of the
memory allocations for wireless buffers were increased from O(0) to
O(1) causing memory fragmentation, and eventually there were no
remaining O(1) fragments. This problem is unlikely to affect most
users as none of the distos turn on the above debug option.

This bug should be marked "closed with patch".

Hmm, I'm remembering differently.  I thought the root problem here has 
only been fixed in Pekka's slab-2.6.git tree with "slub: add option to 
disable higher order debugging slabs" and isn't currently in Linus' tree.

It only happens when CONFIG_SLUB_DEBUG_ON is enabled for caches with 
sizes that increase as the result of the added metadata.

Yup, the fix is in slab.git and queued for 2.6.32. There was some
complaints from Christoph from the patch that need to be addressed
still.

From what I recall, he asked that calculate_sizes() be called twice, first 
to determine if get_order(s->size) increased as the result of the metadata 
and, if so, a second time with the flags disabled.

slab_debug=O only disables debugging options that increase the min order 
of slab as defined in DEBUG_FLAGS; it doesn't selectively disable some of 
them when get_order(s->size) grows.  So it's quite sane, like my patch 
does, to disable all DEBUG_FLAGS when

	get_order(s->objsize) + DEBUG_SIZE_FLAGS > get_order(s->objsize)

without calling calculate_sizes() twice.

We need DEBUG_FLAGS to determine which flags to mask off to reduce the 
minimum order, so I don't see DEBUG_FLAGS_SIZE as troublesome.

Christoph?

My patch is already in Pekka's slab-2.6.git tree at 
http://git.kernel.org/?p=linux/kernel/git/penberg/slab-2.6.git;a=commit;h=fa5ec8a1f66f3c2a3af723abcf8085509c9ee682

You had proposed http://marc.info/?l=linux-kernel&m=124725166205814, which 
moves the mask to kmem_cache_open() and calls calculate_sizes() twice.  
That eliminates DEBUG_FLAGS_SIZE, but I don't see that define as being 
troublesome since we must define DEBUG_FLAGS to specify what options add 
metdata anyway.

My prosal was to use the size and objsize parameters. You would only have
to call calculate_sizes() twice when the comparison of the order of size
and objsize would be different.

Doing so would simplify additing future flags. If you do your own
calculations (like in the patch) then you have to replicate the size
calculation from calculate_sizes() somehow. Is the duplicate calculation
really accurate regarding alignment and other special casing?

Ok, fair enough.  It seems like a matter of taste in implementation but 
your proposal is also more extendable than mine, and I'm definitely not 
going to argue your taste vs. mine when it comes to slub :)

I'll write an incremental patch on top of Pekka's for-next branch to 
implement your idea.

Pavel, is this still an open issue? Plenty tty fixes went into 2.6.31
so maybe we need to backport some of them to -stable?

FYI, the fix (a new slub debugging option) is queued for 2.6.32 and we
don't have plans to backport it to -stable because it depends on SLUB
out-of-memory diagnostic patches and the problem doesn't affect
production configs.

It has patch, just Len doesn't seem to... don't know, read the topic?
http://patchwork.kernel.org/patch/29082/

Can we ping Len somehow to push this patch directly to Linus's tree?

Still waiting for Len (or somebody) to pick them up.

Slightly improved versions of the patches (as also sent to the mailing 
list recently) are at:
- http://bugzilla.kernel.org/attachment.cgi?id=22857
- http://bugzilla.kernel.org/attachment.cgi?id=22858

I'm not seeing any linux-acpi emails from Len since August 14.

So I merged this patch and shall send it along with

thermal_sys-check-get_temp-return-value.patch
acpi-dont-call-acpi_processor_init-if-acpi-is-disabled.patch

in to Linus today.

Thanks for that Andrew. Could you please do the same for my patches in
http://bugzilla.kernel.org/show_bug.cgi?id=13389 (or
http://lkml.org/lkml/2009/8/17/169)?

That BR is on the regression list for 2.6.30. The patches apply cleanly to 
current mainline.

OK, shall do, thanks.



These patches make rather a big mess in linux-next.

Rusty's strangely-named patch:

commit 6949d7cbb26476cbf1ee7b45ac74faacc9eb7cdf
Author:     Rusty Russell <rusty@rustcorp.com.au>
AuthorDate: Thu Aug 13 10:26:38 2009 +1000
Commit:     Stephen Rothwell <sfr@canb.auug.org.au>
CommitDate: Thu Aug 13 10:26:38 2009 +1000

    misc:work_on_cpu-acpi

is now in the acpi tree.  It changes the throttling code so that
set/get_throttling is performed via smp_call_function_single() rather
than via cpumask fiddling.

So in my tree I reworked it so that the new `force' arg gets passed
through appropriately.  It compiles cleanly but I'd suggest that Len
simply drop "misc:work_on_cpu-acpi" and we send it back to Rusty for
some rechecking (sorry).

Rusty/Len: please work out why the title for that patch went silly.

Rusty, please self-administer smackings for

		struct set_throttling_info sti
			= { pr, p_throttling, t_state.target_state };

these things always start out simple and end up not-simple, so some poor
schmuck has to clean them up so stuff doesn't break.

		struct set_throttling_info sti = {
			.pr = pr,
			.p_throttling = p_throttling,
			.target_state = t_state.target_state,
			.force = force
		};

is better!

Sure.  My main motivation is to get rid of cpumasks on the stack; while
there, I tried to fix this up properly.

git-quiltimport uses the patch names, and doesn't extract the title.  I
assume that's what Stephen uses.  I didn't rename the patch when I rewrote
it not to use work_on_cpu.

Meh... same concept applies to function arguments, and we rely on typechecking
to catch that (though we have little choice in C).

OK, I've dropped these from my tree entirely to avoid more problems.

Can you take them?  They're not really at home in my tree.

arch-x86-kernel-acpi-cstatec-avoid-using-work_on_cpu.patch
misc:work_on_cpu-acpi.patch
misc:work_on_cpu-acpi-fix.patch
misc:work_on_cpu-dcdbas.patch

You can fetch them from http://ozlabs.org/~rusty/kernel/rr-latest/

(You'll want to rename the last three something sane...)

Thanks,
Rusty.

git quiltimport assumes "mail-like" patches, so it looks for "From:" and
"Subject:" lines.  I guess it could be made to use the first line of the
patch if there is no subject ...

Those patches are already in today's linux-next so I can't carry them.

Please email them over in the traditional fashion once that situation
has sorted itself out?
