- Merged the convert-cpusets-to-container-infrastructure patches. These
will probably be dropped and redone.
Boilerplate:
- See the `hot-fixes' directory for any important updates to this patchset.
- To fetch an -mm tree using git, use (for example)
git-fetch git://git.kernel.org/pub/scm/linux/kernel/git/smurf/linux-trees.git tag v2.6.16-rc2-mm1
git-checkout -b local-v2.6.16-rc2-mm1 v2.6.16-rc2-mm1
- -mm kernel commit activity can be reviewed by subscribing to the
mm-commits mailing list.
echo "subscribe mm-commits" | mail [email protected]
- If you hit a bug in -mm and it is not obvious which patch caused it, it is
most valuable if you can perform a bisection search to identify which patch
introduced the bug. Instructions for this process are at
http://www.zip.com.au/~akpm/linux/patches/stuff/bisecting-mm-trees.txt
But beware that this process takes some time (around ten rebuilds and
reboots), so consider reporting the bug first and if we cannot immediately
identify the faulty patch, then perform the bisection search.
- When reporting bugs, please try to Cc: the relevant maintainer and mailing
list on any email.
- When reporting bugs in this kernel via email, please also rewrite the
email Subject: in some manner to reflect the nature of the bug. Some
developers filter by Subject: when looking for messages to read.
- Occasional snapshots of the -mm lineup are uploaded to
ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/mm/ and are announced on
the mm-commits list.

scsi fails to build on !HAS_DMA architectures:
drivers/built-in.o(.text+0x20af6): In function `scsi_dma_map':
: undefined reference to `dma_map_sg'
drivers/built-in.o(.text+0x20b5c): In function `scsi_dma_unmap':
: undefined reference to `dma_unmap_sg'
I split those functions out into a new file. Builds on s390 and i386.
scsi: Don't build scsi_dma_{map,unmap} for !HAS_DMA
Move scsi_dma_{map,unmap} into scsi_lib_dma.c which is only build
if HAS_DMA is set.

Why not just put #ifdef CONFIG_HAS_DMA / #endif around the pair of
functions? I don't see the need to add a new Kconfig symbol and a new
file for this.

I prefer a new file over #ifdefs in c files. (New dma-dependent stuff
would also have a place where it could go to.)
But I'll do whatever ends up as consensus :)

50 lines isn't much need for a new file.

OK, so here's an alternative patch:
scsi: Don't build scsi_dma_{map,unmap} for !HAS_DMA
Use #ifdef CONFIG_HAS_DMA for the two dma-dependent functions.

The scsi core shouldn't know anything about dma mappings, so a separate
file is a good idea just to keep the separation clean.

Yep, that's a bug in slub. We take that lock in the IPI handler. If a CPU
is currently holding that lock and then takes the IPI and enters
add_partial(), it'll deadlock.

Perhaps a suitable fix would be local_irq_disable() in flush_slab().

add_partial runs with interrupts disabled. The interrupts are disabled
when we enter SLUB via allocator or free functions.

A cpu cannot enter an IPI handler while interrupts are disabled. That
needs to be always the case when the list_lock is held.

As far as I can tell: Interrupts are always disabled when flush_slab is
run.
Sometimes we use spin_lock_irqsave for the list_lock and at other times
spin_lock if interrupts are already disabled. Is that the problem?

Ahh I see.
SLUB: Fix locking for hotplug callbacks.
Hotplug callbacks seem to be performed with interrupts enabled. Slub requires
interrupts to be disabled for flushing caches.

Hmm, that might be a couple of things, actually.
To see if the patches directly related to hibernation/suspend cause this, can
you please test 2.6.22-rc3 with the patch series at

Yeah, that's the fix-fault-vs-invalidate-race patches, or my poor attempt
to fix them when spufs changed. I suppose I'll have a poke at it next time
I get the powerpc machine fired up.

Andrew, the following fix is needed on top of

migration_thread should not be freezable, or it will break hibernation and

ok, let's go this way.
Cornelia, afaict your patch has no actual delendency upon Dan's
dma-mapping-prevent-dma-dependent-code-from-linking-on.patch, correct? If
so, I can merge it via James and then merge Dan's patch once James has
merged.
If there is a dependency then I guess I merge both into a single diff and
merge it all in one hit.

We don't really need the ifdefs here. If someone incorrectly calls these

removing these ifdefs is that they won't get a compile-time warning, but I
tend to think that this small cost is worth it.

Andrew, thanks for getting that back in there.
mm-fix-fault-vs-invalidate-race-for-linear-mappings.patch broke ocfs2 shared

Ah, I didn't realise you were using that yet. I expect ocfs2 is using
VM_CAN_INVALIDATE there anyway.
Hmm, this becomes easier to deal with after page_mkwrite is merged with
->fault. But for now, can we just lock the page at the do_wp_page site
as well, and change the API? All users I have seen want the page locked
there anyway...

Unfortunately that doesn't work for ocfs2 for exactly the same reasons page
lock doesn't work during a write either - there's a cluster lock inversion
and we might have to zero adjacent pages for an allocating write.
What's involved in merging it with ->fault?
Here's a nasty idea... Would it be valid for ->page_mkwrite to unlock the
page, so long as it's returned in a locked state? Though, do we even need
the page lock that early? It seemed to me that you were adding it for
consistency reasons (I could be wrong though).

I guess you could just fail the page_mkwrite and have it try again? ..
that would require changing it not to always go SIGBUS though.
> What's involved in merging it with ->fault?
Just I have't sent the patch (because at the time there were no
page_mkwrite users to look at).
It is nicer too, because the nopage path only has to call into
the filesystem once, to return the page (the filesystem can check
whether it is for write, and do the page_mkwrite thing at that
time). do_wp_page obviously still involves the extra call, and
that will be with a flag telling the fs that it isn't a "nopage"
fault, but a write fault on an existing page.

You could do that, but you'd have to probably check that it is
within i_size after you relock it, I think... yeah, that might
be the best thing for ocfs to do for now.

Well, ocfs2 already does i_size checks in page_mkwrite, so we're covered
with respect to truncate races.
I'm still not clear though - what was the reason for adding the page locking
there in the 1st place?

Yeah, its to cover page invalidation races. There is a description in
an earlier patch's changelog.

I don't know what you mean. The code is already using
for_each_possible_cpu() and
x86-fix-oprofile-double-free-was-re-multiple-free.patch doesn't change
that.

Yes, the code, i.e. nmi_setup already uses for_each_possible_cpu(), that
is not the problem. The problem is allocate_msr doing a
for_each_online_cpu(), i.e. not allocating for each_possible_cpu. Chris
tested and acked the patch: http://lkml.org/lkml/2007/5/31/36

I think these two should be in the 2.6.22 definite-queue, unless Eric disagrees.

Ok. So how about the attached patch? It's a bit different than discussed,
but I think it's much cleaner because it preserves the current behavior of
the callback and keeps that bit of page locking inside core code. Not tested
as of yet, but I can run it tommorrow.

[PATCH] Release page lock before calling ->page_mkwrite
__do_fault() was calling ->page_mkwrite() with the page lock held, which
violates the locking rules for that callback. Release and retake the page
lock around the callback to avoid deadlocking file systems which manually
take it.

They are simple bug fixes for regression in 2.6.22 so I don't see a reason
to delay them.

AFAICS there's no dependency in that direction.

Came across this while automating allnoconfig, allmodconfig
and defconfig build tests. I haven't checked to make 100% sure but
rework-ptep_set_access_flags-and-fix-sun4c.patch is the most likely candidate
based on the error - patch author cc'd.

IA64 fails to build with allnoconfig due to an error in the !CONFIG_SMP
case. Ths following patch fixes it and should be considered a fix to
rework-ptep_set_access_flags-and-fix-sun4c.patch.
allmodconfig and defconfig tests are still running.

Yeah, allmodconfig tends to fall over in a heap on a lot of the
less-lavishly-maintained architectures. If any of these are specific to
-mm then I guess we should fix them up, prevent the kernel from actually
going backwards.

I recall compiling earlier versions of -mm on this iMac just fine a few months ago.
Now it looks like a bunch of new warnings appeared and if fails to compile for various
reasons in different places. I'm thinking of running -mm in next few days so maybe
something interesting will come up :-)
BTW. This is 'make allnoconfig && make' result:

Ok - this patch seems to check out fine in testing - no more deadlocking.
Andrew, if this is ok with you I'd really like to see that fix in -mm. Ocfs2
shared write mmap will instantly deadlock without it.
>From reading Nick's description of the problem in
mm-fix-fault-vs-invalidate-race-for-linear-mappings.patch I think we're
pretty safe (as I noted before) because Ocfs2 re-checks the mapping under
lock to protect against trucate races. That's been an "unwritten"
requirement of page_mkwrite() anyway.
Speaking of requirements, attached is my sad attempt at documenting the API.
I know it might be merged into ->fault at some point, but we really ought to
have _something_ in the meantime.

[PATCH] Document ->page_mkwrite() locking
There seems to be very little documentation about this callback in general.
The locking in particular is a bit tricky, so it's worth having this in
writing.

ug, OK. I get a ginormous reject when merging ocfs2 on Nick's stuff which
I've been largely ignoring thus far.
Perhaps I need to go back to staging Nick's stuff after the git trees. I'll
take a look.

Huh, I'm a bit confused... I created this patch on top of 2.6.22-rc3-mm1
which most certainly contains a merge of git-ocfs2.patch and the series
which at least contains
mm-fix-fault-vs-invalidate-race-for-linear-mappings.patch.
So, which of Nick's patches are we talking about here?
Btw, I know you tend to handle rejects yourself, but if it's a major PITA
I'd be happy to help out. Boy, I'm hoping I didn't just ask for a load of
trouble there :)

Right. I did a lot of tricksy work for rc3-mm1 to merge git-ocfs2 on top
of Nick's stuff. Then I repulled your tree and lost it all. This is
because I was dumb and I fixed rc3-mm1's git-ocfs.patch rather than doing a
separate fix-rejects-in-git-ocfs2.patch.
This is all unique-to-akpm stuff which you don't need to worry about ;)

Is OK - I'll move Nick's patches back to behind the git trees and it'll all come
good.

Phew ok. Once again, thanks for all the work you do getting the ocfs2 git
patches into -mm.

Some of the later seems to be related to the lack of CONFIG_PM .. it's
not much a lavish maintainership issue than the fact that nobody every
builds the powermac drivers without CONFIG_PM :-) I'll look into fixing
some of these.
As for the ps3 bits, it's a known problem, the ps3 support is still very
much a work in progress.
Cheers,
Ben.

To be fair, almost all of the powerpc allmodconfig build
problems are caused by x86-only drivers (and most of those
I doubt still work on x86, even).
Segher
I'm getting the following compile error in 2.6.22-rc3-mm1 with
CONFIG_X86_CMPXCHG=n (with -Werror-implicit-function-declaration -
otherwise it would be a link error):
<-- snip -->
...

<-- snip -->
Adding a dependency of XEN on X86_CMPXCHG should not be a problem and
not prevent any reasonable real-life usage.
But what worries me is that a seemingly architecture independent
driver uses a function only available in some configurations.

Due to a typo the tea5761 tuner support was dead code.
This patch also fixes a bug in the no longer dead code:
A void function can't return anything.

Good catch. I've folded this fix into i2c-ds1628-new-driver.patch,
thanks for reporting.

Yes, I was feeling somewhat exposed with the options in the top level
config, but at least it got a few more eyes on the code. I will fold in
your patch and move async_tx under lib/ for now, but at some point I
would like to investigate the potential synergies with crypto/.

(And of course, you can't shutdown cleanly, because /etc/init.d/network tries
to down other interfaces on the way out, and....)
I'd bisect this, except I don't have a better way to replicate it than "wait for
our VPN box to reset the connection after 24 hours of connect" - basically means
I get 2 tries per weekend..)
An hour or so of digging through the -rc3-mm1 broken-out/ didn't find any
obvious-to-me culprits. Any ideas/suggestions?

One caveat with this... md.o needs xor.o to be initialized first.
Moving xor.o under lib/ means this assumption is broken since the
top-level Makefile puts 'libs' after 'drivers'.

Herbert can I move async_tx under crypto since the engines I am working
with have support for algorithms like CRC32C and Galois Field Multiply
(raid6 p+q)?

What about using a different initcall level?
Depending on the link order is not such a good idea.

printk_clock() is sched_clock() in disguise, and I'm not sure that making
sched_clock() more widely available in this fashion is something that we
want to do anyway.
Anyway, the statistics patches have just celebrated their first birthday
and I don't see that they're getting sufficient momentum or interest to
ever get into mainline so I think I'll drop them, sorry.

Sure that's fine by me. Although as Adrian said it's probably better
to use something other than alphabetical order :)

This patch contains the following cleanups:
- make the following needlessly global functions static:
- core.c: mmc_schedule_delayed_work()
- core.c: mmc_flush_scheduled_work()
- removes the prototope of the following non-existing function:
- core.h: mmc_schedule_work()
- proper prototypes for three functions from core.c in core.h

Andrew,
the lock contention statistics, which have been added to -mm recently, duplicate
code that we have in the statistics patches. I think I can slim the lock
tracking patches further down considerably (similar to my attempt at
timerstats). I have a working prototype that is getting some polishing brushes.
Would you like to wait how this goes?
As to timestamp_clock(): its useful for statistics, but still a minor feature.
It would be unfortuante if that was the stumbling block for my patches. Am I
right that the fix for the issue pointed at by Adrian is to rename those two
occurrences of printk_clock()? Do you want me to submit a patch?

Note that sched_clock() can not be used early on ARM; it might want to
access MMIO which is not accessible until later in setup_arch(). This
is why ARM's printk_clock() divorces itself from sched_clock().

If it's ends up being based upon sched_clock() instead of printk_clock()
on ARM then it'll break stuff horribly (== non-bootable kernels.)

it usually hangs in different places. Full bootlog below. Same kernel
bzImage boots fine on another box.
the NMI watchdog warning is a bit weird:

initcall 0xc0613e4f ran for 27 msecs: check_nmi_watchdog+0x0/0x1a8()
i'll test it in a minute with that turned off.

yeah, with nmi_watchdog=0 it works fine. nmi_watchdog=2 always worked on
this box so this is some new regression.

In my experience that means that it wedged in a timer tick. Often the first
one.

yeah. I tried !hres and !dynticks too and that doesnt make any
difference to the end result - so my guess is on the NMI watchdog
re-programming thing on K8 CPUs (running the 32-bit kernel), which is
done in every NMI tick. check_watchdog() for some reason thought there's
no NMI, and later on an NMI still arrived? Something like that.
vanilla kernel works fine.

i have put an early_printk() into the NMI handler but it never triggers.

commenting out check_nmi_watchdog() produces a booting kernel too. So
it's a side-effect of check_nmi_watchdog(). Problem is, nothing in nmi.c
changed in -mm1 AFAICS.

ah, plain -rc3 hangs too. So it's one of these commits i guess:
commit 1eeb66a1bb973534dc3d064920a5ca683823372e

oh, damn. The resulting kernel after having undone these doesnt even
build ...

Andi/Linus Cc:-ed - these NMI watchdog changes came over the x86_64
tree. I suspect this patch:
commit 09198e68501a7e34737cd9264d266f42429abcdc
Author: Andi Kleen <[email protected]>
Date: Wed May 2 19:27:20 2007 +0200
[PATCH] i386: Clean up NMI watchdog code
Andi - just boot with nmi_watchdog=2 on a dual-core Athlon64 CPU.

They aren't. They are in neither 2.6.22-rc3 nor 2.6.22-rc3-mm1.bz2,
or in any of the broken-out patches, git-* or other.

Oh. Thanks. I wonder why I dropped it. Does anyone recall what the
status of this is?

I don't know what could have caused this, sorry. If it's still there in next -mm
(which is still 100000 compile fixes away) it'd be good if you could bisect it.
Suspects would be git-net.patch, get-netdev-all.patch and gregkh-driver-*.patch
Thanks.

"divident" does appear to be a word, but I suspect "dividend" was intended.
Why is this function lurking in the CPU scheduler rather than in
lib/somewhere.c?
Doesn't an unsigned divide give the same result as a signed one?

In this case it's not that bad. It makes the source quite a bit cleaner
and avoids having to create artificial interfaces, global functions,
etc. between the .o's.

yeah indeed - fixed.

no! 0xfffffff0 / 2 is 0x7fffffff when the division is unsigned, and
7ffffff8 (== -8) when signed. On x86 the silicon only offers us unsigned
64-bit division, so we first have to make '+16' out of -16, then divide
by 2, and turn the +4 into -4. (On x86_64 there's no such problem,
there's an idiv and a div 64-bit instruction as well, and gcc picks the
right one depending on the type of the variable.)
i think Roman has recently done a nice cleanup patch that introduces
this? I'll change CFS to use that interface once it's upstream.

The idiom used in the kernel for such code is "global code and compile
the files separately". The expected inclusion for a C file into the
kernel is through the Makefile, and everything else is surprising when
looking through the code.
"artificial interfaces" is not a problem since these are completely
private interfaces you can change at any time.

attached below. nmi_watchdog=2 still hangs as of -rc5, using the 32-bit
kernel (at various places during bootup - a typical place is somewhere
after cfq_init()). Changing it to nmi_watchdog=0 makes the kernel boot
again.

Still no hang here. Just to make sure that I didn't mess the test up,
here's what I did:
Get pristine 2.6.22-rc5 kernel sources.
Put your config in place as .config
Run: make ARCH=i386 CFLAGS_KERNEL="-m32" AFLAGS_KERNEL="-m32"
Install the kernel.
Reboot, pass "nmi_watchdog=2" as kernel parameter.
As your config is for a 64bit kernel, several config items had to be set
manually. In one run, I accepted the default values, in the second run,
I tried to adjust those items to match your 64bit config as good as I
could.
Anything wrong with that?

FYI, latest -git _still_ hangs with the NMI watchdog with
nmi_watchdog=2, at the same place:

[PATCH] i386: PARAVIRT: Consistently wrap paravirt ops callsites to make them patchable
... our wonderful paravirt subsystem, honed to eternal perfection by the
testing-machine x86_64 tree.
reverting -git-curr's paravirt.c, paravirt.h, smp.c and tlbflush.h to
before the bad commit makes the NMI watchdog work again. Patch against
-rc6 is below.

- * These macros are intended to wrap calls into a paravirt_ops
- * operation, so that they can be later identified and patched at
- * runtime.
- *
- * Normally, a call to a pv_op function is a simple indirect call:
- * (paravirt_ops.operations)(args...).
- *
- * Unfortunately, this is a relatively slow operation for modern CPUs,
- * because it cannot necessarily determine what the destination
- * address is. In this case, the address is a runtime constant, so at
- * the very least we can patch the call to e a simple direct call, or
- * ideally, patch an inline implementation into the callsite. (Direct
- * calls are essentially free, because the call and return addresses
- * are completely predictable.)
- *
- * These macros rely on the standard gcc "regparm(3)" calling
- * convention, in which the first three arguments are placed in %eax,
- * %edx, %ecx (in that order), and the remaining arguments are placed
- * on the stack. All caller-save registers (eax,edx,ecx) are expected
- * to be modified (either clobbered or used for return values).
- *
- * The call instruction itself is marked by placing its start address
- * and size into the .parainstructions section, so that
- * apply_paravirt() in arch/i386/kernel/alternative.c can do the
- * appropriate patching under the control of the backend paravirt_ops
- * implementation.
- *
- * Unfortunately there's no way to get gcc to generate the args setup
- * for the call, and then allow the call itself to be generated by an
- * inline asm. Because of this, we must do the complete arg setup and
- * return value handling from within these macros. This is fairly
- * cumbersome.
- *
- * There are 5 sets of PVOP_* macros for dealing with 0-4 arguments.
- * It could be extended to more arguments, but there would be little
- * to be gained from that. For each number of arguments, there are
- * the two VCALL and CALL variants for void and non-void functions.
- *
- * When there is a return value, the invoker of the macro must specify
- * the return type. The macro then uses sizeof() on that type to
- * determine whether its a 32 or 64 bit value, and places the return
- * in the right register(s) (just %eax for 32-bit, and %edx:%eax for
- * 64-bit).
- *
- * 64-bit arguments are passed as a pair of adjacent 32-bit arguments
- * in low,high order.
- *
- * Small structures are passed and returned in registers. The macro
- * calling convention can't directly deal with this, so the wrapper
- * functions must do this.
- *
- * These PVOP_* macros are only defined within this header. This
- * means that all uses must be wrapped in inline functions. This also
- * makes sure the incoming and outgoing types are always correct.

Er, wow. I've been running with this stuff for months without a
problem. Do you have CONFIG_PARAVIRT enabled? Do you still get the
hang if you boot with "noreplace-paravirt" to disable the patching?
Your revert patch seems to take out quite a lot of stuff, some unrelated
to the paravirt_ops. Where did that come from?
I presume there's one bad callsite in here which is used by the nmi path
more or less exclusively. Is the bug simply that it hangs if you boot
with nmi_watchdog=2? ie, no other details?

What's this? This isn't paravirt_ops related, is it?

Crap. That's embarrassing. Does it help, because it seems likely?
(Esp since Ingo didn't even have CONFIG_PARAVIRT enabled, so most of his
revert would have been dead code anyway.)

He has. The config Ingo sent was for x86_64, which (AFAICT) doesn't have

Are you running on AMD hardware? As Intel performance counters are only
32 bits wide, the wrmsrl bug should be a non-issue at least for the NMI
watchdog on Intel hardware. AMD uses 48bit wide performance counters,
which are probably less happy ;-)

this did the trick, rc6 plus your fix and the NMI watchdog works again!
Thanks! I suspect other code (oprofile?) broke due to this too.
below is a tidied up patch for upstream application. Must-have for
2.6.22.

Subject: [patch, 2.6.22-rc6] fix nmi_watchdog=2 bootup hang, take #2
wrmsrl() is broken, dropping the upper 32bits of the value to be
written. This broke the NMI watchdog on AMD hardware. (and it
probably broke other code too.)

Still present as of 2.6.22-rc6-mm1.

Sorry, must have missed this one. Um, yeah, I guess we have a
dependency on cmpxchg. I'll do a patch.
