- If something goes wrong with a PCI device's probing or initialisation, try
  reverting pci-disable-decoding-during-sizing-of-bars.patch.

- git-sched was dropped due to breaking suspend-to-RAM.

- git-block has been restored after having had a few problems

- git-newsetup.patch was dropped due to conflicts with git-x86

- git-perfmon.patch is still dropped for the same reason

- git-kgdb.patch is still dropped for the same reason

- Please do try to cc the correct developer and mailing list when
  reporting problems - I'm just buried in bugs over here.



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 majordomo@vger.kernel.org

- 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.  These probably are at least compilable.

- More-than-daily -mm snapshots may be found at
  http://userweb.kernel.org/~akpm/mmotm/.  These are almost certainly not
  compileable.

Re: 2.6.24-rc5-mm1 kobject changes broken with hvcs driver on powerpc - regression

[Kamalesh Babulal]

Hi,

The kernel build fails with following error message

drivers/char/hvcs.c: In function 'hvcs_open':
drivers/char/hvcs.c:1180: error: wrong type argument to unary exclamation mark
make[2]: *** [drivers/char/hvcs.o] Error 1
make[2]: *** Waiting for unfinished jobs....

This driver was broken in 2.6.24-rc4-mm1 either on powerpc, and the discussion
has been going on at

Is it the same suspend-to-RAM problem that Jiri Slaby reported 
here --> http://lkml.org/lkml/2007/12/7/125

The problem has been identified and a fix patch was provided.


Thanks and Regards

Re: 2.6.24-rc5-mm1

[Pierre Peiffer]

Hi,

	My config does not link any more:

...
  CHK     include/linux/compile.h
  UPD     include/linux/compile.h
  CC      init/version.o
  LD      init/built-in.o
  LD      .tmp_vmlinux1
net/built-in.o: In function `xs_udp_data_ready':
/home/peifferp/containers/kernel/linux-2.6.24-rc5-mm1/net/sunrpc/xprtsock.c:842:
undefined reference to `udp_stats_in6'
/home/peifferp/containers/kernel/linux-2.6.24-rc5-mm1/net/sunrpc/xprtsock.c:846:
undefined reference to `udp_stats_in6'
make[1]: *** [.tmp_vmlinux1] Error 1
make: *** [sub-make] Error 2

After a first look, udp_stats_in6 seems to be defined in ipv6 (file
net/ipv6/udp.c) but I have

CONFIG_IPV6=m
and
CONFIG_SUNRPC=y

So, SUNRPC uses something defined in a module in my case ?

... looking more, this dependency seems to have been introduced by the patch
[UDP]: Restore missing inDatagrams increments
( http://thread.gmane.org/gmane.linux.network/79716/focus=79831 )

(I cc netdev)

I don't know what is the right way to fix this ... ?

Re: 2.6.24-rc5-mm1

[Benjamin Thery]

The problem comes from the new macro UDPX_INC_STATS_BH introduced
by Herbert, which was a nice addition to increment the correct 
UDP MIB depending on the socket family, but unfortunately 
the use of this macro from kernel code (I mean code not compiled 
as module) requires that IPv6 is also compiled in kernel 
(CONFIG_IPv6=y) in order to have udp_stats_in6 defined at link 
time.

you might do "select IPV6" in the SUNRPC section of fs/Kconfig, however select is
evil...

This is a simple fix to the new api, sorry, being ppc I missed it in my
build tests.

select itself isn't evil.

Nonsensical selects like the one you suggest (sunrpc does not require 
IPV6) are evil.

Don't think so (I hit that one too, I think).

There's no mention of get_online_cpus() in git-sched's watchdog(), and my
symptoms are that the machine appears to suspend to RAM OK (but it might
take longer to do this with git-sched applied).  But it never comes back to
life after you hit the power button to resume it.  

I guess I need to bisect it.  That'll be novel.

OK, let's just move udp_stats_in6 into net/ipv4/udp.c.  It's only
40 bytes or less.

[UDP]: Move udp_stats_in6 into net/ipv4/udp.c

Now that external users may increment the counters directly, we need to
ensure that udp_stats_in6 is always available.  Otherwise we'd either
have to requrie the external users to be built as modules or ipv6 to be
built-in.

This isn't too bad because udp_stats_in6 is just a pair of pointers plus
an EXPORT, e.g., just 40 (16 + 24) bytes on x86-64.

Hi,
The behaviour of my mp3 player (also act as usb-storage device) seems
changed from rc5 to rc5-mm1.

<dmesg output under rc5>:

try mount it (or just blockdev --rereadpt), then write protect become off:

But under rc5-mm1, after mount command being executed, it is just
mouted as read only partition without set the write-protect to off

I tried "blockdev --rereadpt", it do set the write-protect to off as rc5 kernel.

Below is the output of dmesg under rc5-mm1

This can't be considered a bug, right?  It's just that the player 
changed from one slightly non-standard behavior to a different slightly 
non-standard behavior.

This output won't appear if you simply mount the device.  So how do you 
know that mounting turns off write protect?

This looks exactly the same as the output above (except for various 
port, device, and bus numbers).

If you turn on CONFIG_USB_STORAGE_DEBUG for both kernels and compare 
the dmesg output for the mount command, that might highlight the 
difference.

Applied.

FWIW, I got the following at reboot after some tests were finished:

get_unused_fd: slot 3 not NULL!
get_unised_fd: slot 4 not NULL!
general protection fault: 0000 [1] PREEMPT SMP
last sysfs file /sys/class/scsh_host/host1/link_power_management_policy

and that's all.

Broken @#$%^ suspend, again (and maybe still for a longer time). Unable to
reproduce this with netconsole.

trace led to i915_suspend
        call    pci_bus_read_config_byte        #
        movq    8(%rbx), %rdi   # <variable>.mmio_map, <variable>.mmio_map
        movq    24(%rdi), %rax  # <variable>.handle, D.24395
        movl    458760(%rax), %eax      #, D.24397

address in rax (i.e. dev_priv->mmio_map->handle) is broken, at least it seems so
from the part of the trace and RIP.

        movl    %eax, 408(%rbx) # D.24397, <variable>.savePIPEACONF
        movq    24(%rdi), %rax  # <variable>.handle, temp.676
        movl    393244(%rax), %eax      #, D.24399

in
        pci_save_state(dev->pdev);
        pci_read_config_byte(dev->pdev, LBB, &dev_priv->saveLBB);

        /* Pipe & plane A info */
-->     dev_priv->savePIPEACONF = I915_READ(PIPEACONF);

I use distro pm-utils and it chvt's to some terminal, write out the output,
suspend, resume, switch back to X.

The patch I'm currently using for debugging:

map ffff81007bd7df80, HANDLE: ffff81007cc33e10

What's this HANDLE address, it has probably nothing to do with the mapping --
note that "BLE drm_addmap_core a" is _between_ "map = drm_alloc" and map->handle
= NULL;". How this address leaked to the i915 handle? Maybe some other place I
haven't spotted which changes handle? Anyway, the mapping ffff81007bd7df80 seems
to be removed in last but one line ("BLE drm_rmmap_locked a").

Re: 2.6.24-rc5-mm1: cat /proc/net/packet -> oops

[Mariusz Kozlowski]

[-- Attachment #1: Type: text/plain, Size: 3514 bytes --]

Hello,

	As one of usual tests I run the following script:

for i in `find /proc -type f`; do
        echo -n "cat $i > /dev/null ... ";
        cat $i > /dev/null;
        echo "done";
done

This time the culprit is /proc/net/packet. cat process gets killed 

$ cat /proc/net/packet 
Segmentation fault

and lost in lots of messages from the script but for some reason there is no
info in syslog (why?). I could capture the oops only when issued sysrq-7
or grater. That's why I didn't catch the oops earlier.

I found it because the bug makes my sparc64 box need a hardware reset most of the
time it happens and produces oops 2 screens long. x86 kills the cat process but
system is still usable and running fine. Bisection points to:

git-ubi.patch
GOOD
#
git-net.patch 
BAD
ipsec-fix-reversed-icmp6-policy-check.patch

but this seems to be far from precise :)

$ grep ^commit git-net.patch | wc -l
361

Not sure if this is important but when bisecting the mm tree the oops got shorter
at some point so maybe some other patch is also involved. This one is from x86:

I suspect namespace borkage.  But just because you pin-pointed
my patch I'll try to track it down :)

Surprise surprise.  The namespace seq patch missed two spots in
AF_PACKET.

[PACKET]: Fix /proc/net/packet crash due to bogus private pointer

The seq_open_net patch changed the meaning of seq->private.
Unfortunately it missed two spots in AF_PACKET, which still
used the old way of dereferencing seq->private, thus causing
weird and wonderful crashes when reading /proc/net/packet.

This patch fixes them.

Beats me - nobody has been fiddling with that code for a while.  Worrisome.

Re: 2.6.24-rc5-mm1: problems with cat /proc/kpageflags

[Mariusz Kozlowski]

Hello,

	cat /proc/kpageflags on sparc64 causes the box to lock.
I can not write on any terminal - but I can issue sysrqs and switch
between consoles.

cat process hangs in read(3, ...

sysrq-w shows:

syslogd       D 000000000069240c     0  2470      1

Will reply soon with correct data.

Re: 2.6.24-rc5-mm1: problems with cat /proc/kpageflags

Hello

> Will reply soon with correct data.

Ok here it goes:

        cat /proc/kpageflags on sparc64 causes the box to lock.
I can not write on any terminal - but I can issue sysrqs and switch
between consoles.

cat process hangs in read(3, ...

sysrq-w shows:

syslogd       D 000000000069240c     0  2470      1
Call Trace:

then when I try to ssh to the sparc machine I fail but at sparc you
can see this:

When this happens box seems to react only to sysrq-b or manual reset.
Anything else is useless.

cat /proc/kpagecount produces similar symptoms. box is locked - sysrq-w sshd trace:

__down
__down_interruptible
kobject_get
lock_kernel
chrdev_open
__dentry_open
nameidata_to_filp

then again:

or:

Perhaps this is related to sparsemem.

Can you change line 710 of fs/proc/proc_misc.c to:

	ppage = NULL;

..and see if it still breaks?

Mathematics is the supreme nostalgia of our time.

Sure.

Yes it does - the same way as eariler. Box is locked, processes stuck in D state
and after a while "BUG: soft lockup - CPU#0 stuck for 11s!".

My mistake. I run cat /proc/kpageflags in the first place - so how could anything change :)

cat /proc/kpagecount on the other hand - with the change in line 710 - locks the box.
Sysrq works, changing consoles works, but there is no "BUG: soft lockup ..." message.
After a while the box becomes totaly unresponsive - even caps lock doesn't work, no
responses to ping.

Yes, but lacks the part of "'Write Protect if off'  and other lines".

Well I'm baffled. There's basically two things in that function that
do anything interesting: pfn_to_page and put_user. access_ok is
"return 1" on Sparc64. atomic_read is a simple read.

My usual approach at this point would be to litter it with printks and
see where its hanging.

But as the function doesn't actually show up in your stack trace,
something else is probably wrong. So I'd also try commenting out
pieces of that function until it started working.

Some piece of state is being indirectly corrupted and this
is showing up later in some unrelated operation.

Can someone send me this kpageflags patch under seperate
cover?  I'll try figure out why it farts on sparc64.

This sounds a lot like a problem we had recently.  The driver wasn't 
preserving its mappings across X startup/shutdown (drm open/close) and so 
you'd see crashes like this.  It should be fixed already in DRM git.

Ok. Maybe this will help. Don't know how to compare that to the results from yesterday
(test with ppage = NULL) - maybe I f.... something up. This time I added a bunch
of printks and got these results:

This is from 'cat /proc/kpageflags' (after this the box is locked):

    01
    pfn:0, src:0, KPMSIZE:8
    23458
    ppage:0000000200000000, pfn:1

and the relevant code:

static ssize_t kpageflags_read(struct file *file, char __user *buf,
			     size_t count, loff_t *ppos)
{

	u64 __user *out = (u64 __user *)buf;
	struct page *ppage;
	unsigned long src = *ppos;
	unsigned long pfn;
	ssize_t ret = 0;
	u64 kflags, uflags;

printk("0");

	if (!access_ok(VERIFY_WRITE, buf, count))
		return -EFAULT;

printk("1");
	pfn = src / KPMSIZE;
printk("\npfn:%u, src:%u, KPMSIZE:%d\n", pfn, src, KPMSIZE);
	count = min_t(unsigned long, count, (max_pfn * KPMSIZE) - src);

printk("2");
	if (src & KPMMASK || count & KPMMASK)
		return -EIO;

printk("3");
	while (count > 0) {
printk("4");
	ppage = pfn_to_page(pfn++);
printk("5");
		if (!ppage) {
printk("6");
			kflags = 0;
printk("7");
		} else {
printk("8");
printk("\nppage:%p, pfn:%u\n", ppage, pfn);
			kflags = ppage->flags; // <---------------- something bad happens
printk("9");
		}

printk("a");



This is from 'cat /proc/kpagecount' (after this the box is locked)

    01
    pfn:0, src:0, KPMSIZE:8
    23567a
    ppage:0000000200000000, pfn:1

and this is the relevant code:

static ssize_t kpagecount_read(struct file *file, char __user *buf,
			     size_t count, loff_t *ppos)
{

	u64 __user *out = (u64 __user *)buf;
	struct page *ppage;
	unsigned long src = *ppos;
	unsigned long pfn;
	ssize_t ret = 0;
	u64 pcount;
printk("0");
	if (!access_ok(VERIFY_WRITE, buf, count))
		return -EFAULT;

printk("1");
	pfn = src / KPMSIZE;
printk("\npfn:%u, src:%u, KPMSIZE:%d\n", pfn, src, KPMSIZE);

printk("2");
	count = min_t(size_t, count, (max_pfn * KPMSIZE) - src);
printk("3");
	if (src & KPMMASK || count & KPMMASK) {

printk("4");
		return -EIO;
	}
printk("5");
	while (count > 0) {
printk("6");
		ppage = pfn_to_page(pfn++);
printk("7");
		if (!ppage) {
printk("8");
			pcount = 0;
		} else {
printk("a");
printk("\nppage:%p, pfn:%u\n", ppage, pfn);
			pcount = atomic_read(&ppage->_count); // <---------------- something bad happens
printk("b");
		}

OK, so I'm trying to 'dd' a CD and the drive on the laptop is having issues
reading the disk.

I try it once, and get an I/O error about 117M in - dd reports 1.7M/sec.

I try it again, and it reports it died at the same exact place, but in about
2 seconds flat, and reports 91M/sec transfer.  OK, that's *weird*, I didn't
think that blocks read from /dev/cdrom would get cached, but OK.  So I try
the obviously stupid thing:

# echo 1 >| /proc/sys/vm/drop_caches

Alas, that hangs gloriously - 'echo t > /proc/sysrq-trigger' tells me:

It'll remain cached if something is holding the device open.

Something's holding s_umount for writing I guess.  Possibly busted error

Does it need to be "device open", or are there other things as well? If the
drop_cache was hosed, that would result in the same symptoms, no?

Aha - found what was holding it - an attempt to loopback mount the truncated

I don't mind it failing the mount, but the oops seems excessive.  I suspect
that *somewhere* in that stack trace, we're wanting something like a

but I admit not being competent enough to decide where that should be.

Yup.

David, this is concerning.  More such error-path bugs in that code will
take years and years to get found and fixed.  The best way to eliminate
them is a line-by-line re-review of the patchset.

With that patch applied, I took the ISO image (which I ended up reading on
another machine and copying over the net to get a complete usable image),
and dd'ed just the first 150M into another file, and tried to loopback mount
it.  And I got:

# mount -o ro,loop /path/to/cd.partial.image /mnt/loop
mount: wrong fs type, bad option, bad superblock on /dev/loop0,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

And my dmesg says:

[   33.622073] ISO 9660 Extensions: Microsoft Joliet Level 3
[   33.622125] attempt to access beyond end of device
[   33.622129] loop0: rw=0, want=1284500, limit=300000
[   33.622133] ISOFS: unable to read i-node block
    Here is where we would oops before - now it errors out more reasonably:
[   33.622140] ISOFS: changing to secondary root
[   33.622148] attempt to access beyond end of device
[   33.622151] loop0: rw=0, want=1284508, limit=300000
[   33.622155] ISOFS: unable to read i-node block
[   33.622159] isofs_fill_super: get root inode failed

So that fixes *this* bug. I looked in the -rc5-mm1 broken-out/, saw
the vast multitudes of 'iget-stop-<foofs>-from-using' patches, and decided
that somebody else will probably have to audit them for sanity.

In the iget-* series, there's some 184 'return ERR_PTR(-E<FOO>);' for some FOO,
and 3 other uses:

isofs is the only place we don't return a constant 'ERR_PTR(-EFOO)', but
cast somebody else's return value.  I wish I understood what that tells us. ;)

git-net.patch (I'm guessing one of Daniel's commits, but not sure which one)
causes some complaints:
 
  LD      vmlinux.o
  MODPOST vmlinux.o
WARNING: vmlinux.o(.init.text+0x2263f): Section mismatch: reference to .exit.text:tcpv6_exit (between 'inet6_init' and 'ac6_proc_init')
WARNING: vmlinux.o(.init.text+0x22644): Section mismatch: reference to .exit.text:udplitev6_exit (between 'inet6_init' and 'ac6_proc_init')

WARNING: vmlinux.o(.init.text+0x226bc): Section mismatch: reference to .exit.text:rawv6_exit (between 'inet6_init' and 'ac6_proc_init')

Looks like the problem is that tcpv6_exit and friends are called from
net/ipv6/af_inet6.c:inet6_init() - which is declared as:

static int __init inet6_init(void)

I can see how calling an __exit from an __init would be Bad Juju...

Yep, thanks Valdis for pointing that.

I sent a patch several days ago which fix that to DaveM and he applied 
it to the latest net-2.6.25

Nope.  The correct fix is to make the various callers use IS_ERR() to check
the result of this function rather than checking for a NULL return.

Yes, I know.  I've looked over the patches several times, however I know there
may be bugs in there because I may have made assumptions about what I've
written that cause me to overlook things.  It's a danger of checking your own
code:-(

And ideally by someone other than me.  Some of them have been reviewed by
other people, but I'm not sure that all have.

However, I've just had another look through.  ISOFS appears to be the only one
in which I'd missed updating the callers.  I've sent you a patch for it.

Note that I expressed reservations about three filesystems in the cover note
(FAT, HPPFS and HOSTFS), but nothing seems to have come of it.

Hi,

The oops is at iput, I use 'return NULL ' is because I don't want to
change the the behaviour of iput in fs/inode.c.

Nobody seems to look after hppfs.  I'll resend the fat and hostfs patches to
maintainers for a review, please.

There's not useful infomation with DEBUG on.

I tested on another machine with kernel 2.6.24-rc2. And the result is
diffrent again.
Here is the result:

1. on 2.6.24-rc2, when I plugin the player the kernel reports below messages:

usb-storage: waiting for device to settle before scanning
/*[lets mark the below part as part 1]*/

 sda: sda1

2. on 2.6.24-rc5 kernel reports only the part 1, after try mount the
disk it reports the part 2 and mount the partition as rw

3. on 2.6.24-rc5 kernel reports only the part 1, after try mount the
disk it just mount the partition as ro with nothing more messages.

This is not normal.  When you plug in a storage device you should get 
all of the messages in your part 1 plus the first two lines in your 
part 2, but not the rest of part 2.

You must have a typo there.  Those can't both be true for 2.6.24-rc5.  
In fact you shouldn't see part 2 at all.

Here's what I get when I plug in a USB mass-storage device under 
2.6.24-rc5:

[   87.903014] usb-storage: device found at 2
[   87.909570] scsi 0:0:0:0: Direct-Access              Memorex TD 2B    1.09 PQ: 0 ANSI: 0 CCS

Mounting the disk produces no extra output at all.  I get the same 
result under 2.6.23 and earlier operating systems.  You should see 
approximately the same thing.

Hi, Alan

I'm sure about my post. I'm not so famillar with usb.
It looks weird.  Seems that my device will be firstly recoganized as a
mp3 player and then a usb storage, so the system will report part 1 &
part 2 under previous  kernels.

So which is correct?

But your post contradicts itself.  It can't be correct.

I think those "part 2" messages aren't caused by the kernel at all, but
instead by some program running on your computer.  You could try
booting into single-user mode and see if the behavior changes.

Also there's no question -- the device does behave strangely.  It
shouldn't change the write-protect setting all by itself.

Oh, sorry. It's a typo. should be 2.6.24-rc5-mm1

No doubt for me. Under osx plugin this device will popup a dialog(I
don't remember the content), after press ok then the disk icon go
away, and then being remount again.

Yes, I think so too.

Yes these two were enough, and exporting fs/proc/base.c's
mem_lseek().

As hard as I try, I can't reproduce this at all.  I tried
both on my workstation and my niagara boxes.

It must be other needle in the 30MB+ -mm haystack. :-(

Andrew,

I re-based the for_mm branch at:
http://git.kernel.org/?p=linux/kernel/git/jwessel/linux-2.6-kgdb.git;a=shortlog;h=for_mm
against the git-x86/mm branch from the x86-git tree. If there are other
patch trees I need to pull in and patch against to allow for kgdb to be
included into -mm please let me know.

I would like to submit another review request for kgdb into the mainline
as well as resolve the issues with the -mm tree + kgdb.

Thanks,
Jason.

That's good to know, I was having a very hard time imagining how the
kpagecount code could be going south.

Have we seen a config for the broken machine? Perhaps that'll help us
make a guess..

I'm afraid you are wrong. Eariler kernel are affected as well. At reading your mail I was
thinking of applying those two patches to 2.6.24-rc5 and do bisection on the rest of -mm series.
Unfortunately clean 2.6.24-rc5 with these two patches is affected as well (new processes
stuck in D state etc). So I tried vanilla 2.6.23 patched by these two patches (and
mem_lseek export from fs/proc/base.c). Now at least I got a trace produced by 'cat /proc/kpagecount'
which you can find below. Also, in spite of the oops, the box doesn't get locked (as with -mm)
and is still usable.

Please do - just email out the patches with carefully-chosen cc's.  It's
not a hugely productive time of year and responses may be spotty and slow
but you should just persist - send them every couple of weeks and let's
drive this nail home.

My suspicion at this point is that with certain RAM layouts, simply
iterating over PFN's is simply not working out.

pfn_to_page() seems to be doing no range checking, and with sparsemem
vmemmap, which sparc64 always uses, this can be problematic.

It just blindly goes "vmemmap + pfn" which is asking for trouble, in
particular when the physical RAM layout really is sparse.

Maybe it's enough to add a pfn_valid() check here?  If pfn_valid()
means there is a vmemmap translation setup for that page struct too,
it would work.

That was my original suspicion, which is why I asked Mariusz to
effectively comment out the actual PFN lookup up-thread. I didn't send
him a patch to do that, so I guess my instructions on how to hack it
may have been misunderstood.

Yes that should work, please use "NULL" in the final
version of the patch instead of "0" so that sparse is
happy.

Thanks.

Andrew,

Given the churn in patches I think the best approach is to put kgdb
after you have cut a -mm1 so it can go in -mm2 or as a fix or however
you would like to manage it.  The churn should be a whole lot less once
the new kgdb arch support gets merged.

I updated the for_mm branch to be against 2.6.24-rc5-mm1, and it will
merge cleanly.  I can update again once the next mm branch is available.


Thanks,
Jason.

No. I just made a trivial mistake :-/ Sorry for confusion. I guess I need to
verify things three times before sending an email next time.

Thank you for testing -mm (especially on sparc64) and for reporting
