- The x86 git tree has been dropped due to runtime failure on one of my test
machines

- The kgdb tree remains dropped due to git-x86 clashes

- The git-newsetup tree remains dropped due to git-x86 clashes

- The git-perfmon tree remains dropped due to git-x86 clashes

- Andi's x86 quilt tree remains dropped due to git-x86 clashes

- The ext4 tree is dropped because it contains work which clashes with
pending 2.6.25 material


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 ***@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.

Hi Andrew,

The 2.6.24-mm1 kernel build fails with

arch/x86/mm/pgtable_32.c: In function `pgd_mop_up_pmds':
arch/x86/mm/pgtable_32.c:302: warning: passing arg 1 of `pmd_free' from incompatible pointer type
arch/x86/mm/pgtable_32.c:302: error: too few arguments to function `pmd_free'

I have tested the patch for the build failure only.

Looks good to me, it seems like a conflict between origin.patch and

- The x86 git tree has been dropped due to runtime failure on one of my test
machines
ouch - rather unlucky timing. You updated to a fresh x86.git tree which
had this bug for a window of about 103 minutes (according to gitweb). It
is fixed in current x86.git.

Hi Andrew,
The 2.6.24-mm1 kernel build fails at many places with section type
conflict build error.
What arch?
We have troubles with powerpc as pointed out by Al in another thread.

Hi Sam,

This clean up is done for the powerpc, sorry forgot to mention it.

Hello,

This is from ppc32:

Leftover from introduce-flags-for-reserve_bootmem.patch?

We did this wrong. We should have introduced a new reserve_bootmem_foo()

Well, my original proposal was to add a new function but then someone
complained that we already have too much bootmem functions. I don't
remember if this was on LKML or internally in Bugzilla.

However, sorry, it was my fault of course.

Please chuck out:
add-new-string-functions-strict_strto-and-convert-kernel-params-to-use-them.patch
(along with Randy's perfectly reasonable -fix.patch).

So predictable that it would just disable loading modules with params:
Feb 4 13:17:02 blonde kernel: thinkpad_acpi: `1' invalid for parameter `experimental'

Maybe it's something as simple as a trailing whitespace issue,
I haven't looked, would prefer the originator to do so.
openSUSE 10.3 if that makes any difference.

Please don't even begin to think of apologizing to me:
that's so much the wrong way round it's embarrassing.

It's scary to think of how much of your time gets wasted

Thanks. That'll be Russell's x86-amd-thermal-interrupt-support-fix-2.patch.

It looks like that patch is due for a serious overhaul so I think I'll just
drop the version whcih is in -mm, OK?

well that depends on which -mm you tried; I'm sure the mm kernel of the day had it for a while.
I don't think it's a realistic expectation to delay every bugfix and arch patch until Andrew
gets around to releasing an -mm, not do I see the point of that, what would have been different?

I looked around on www.kernel.org, and I found this directory:

http://www.kernel.org/pub/linux/kernel/people/akpm/mm/ but the most recent is:

broken-out-2007-11-20-01-45.tar.bz2 20-Nov-2007 09:45 3.4M

24-rc8-mm1 came out on Jan 17, only a week before 2.6.24 came out and the
merge window opened. Since this stuff wasn't in there in rc8-mm1, but
did go into Linus's tree on Jan 30, it had at best 2 weeks for testing by
whoever pulled the git-x86 tree in that timespan...

x86: make ioremap() UC by default

Yes! A mere 120 c_p_a() fixing and rewriting patches later,
we are now confident that we can enable UC by default for
ioremap(), on x86 too.

That's one hell of a patch series for a "bugfix" that goes straight-to-mainline.

yes it was a really painful bugfix, but still.

I'll repeat the question. What would waiting for an -mm release have bought for this bugfix?

Just wondering what happened to the "large changes should percolate in -mm
for a bit beforehand" concept. We've seen a lot of patchsets that totalled
up to a *lot* less intrusiveness get pushed off with "This needs to cook in
-mm for a while".

Builds, boots, mostly seems to run for limited testing.
One note - the following commit(s) (and related CPA reworking) broke the NVidia
binary driver (which is OK, I can fix *that* part). But can somebody explain
if this should have seen a trip through the -mm tree before it hit mainstream?
well that depends on which -mm you tried; I'm sure the mm kernel of the day had it for a while.

http://userweb.kernel.org/~akpm/mmotm/ contains the latest -mm tree. Updated
more-than-daily when it's changing.

Because hpet_rtc_interrupt()'s call to get_rtc_time() ends up
resolving to include/asm-generic/rtc.h's (hilariously inlined)
get_rtc_time(), which does spin_unlock_irq() from hard IRQ context.

The obvious patch fixes it.

bl6-13 (4-way x86_64 machine) from test.kernel.org is failing to boot recent
-mm and mainline trees. I noticed it when testing -mm before rebasing other
patches but the oops on mainline looks the same. The full console log is
below but the important difference between a working and non-working kernel
is the following

-PERCPU: Allocating 62512 bytes of per cpu data
-Built 1 zonelists in Node order, mobility grouping on. Total pages: 255875
+PERCPU: Allocating 65560 bytes of per cpu data
+cpu with no node 2, num_online_nodes 1
+cpu with no node 3, num_online_nodes 1
+Built 1 zonelists in Node order, mobility grouping on. Total pages:
251257

"cpu with no node 2" is actually saying that cpu 2 has no node and the
message is a just misleading. The number of online nodes and cpu mappings
are not adding up as I got this from a debugging patch

Online nodes
o 0
CPU <-> node mappings (cpu_to_node)
o CPU 0 -> 0
o CPU 1 -> 0
o CPU 2 -> 1
o CPU 3 -> 1

As the failing code in __alloc_pages() is;

restart:
z = zonelist->zones; /* the list of zones suitable for gfp_mask */
if (unlikely(*z == NULL)) {

it implies that an attempt is been made to use an uninitialised zonelist.

If I bodge cpu_to_node() to returning 0,the machine boots but I didn't
see an obvious candidate in origin.patch for the root-cause when I looked
around. I'll bisect this in the morning if this is not a known problem
and no one suggests a possibility.

bl6-13 (4-way x86_64 machine) from test.kernel.org is failing to boot recent
-mm and mainline trees. I noticed it when testing -mm before rebasing other
patches but the oops on mainline looks the same. The full console log is
below but the important difference between a working and non-working kernel
is the following
-PERCPU: Allocating 62512 bytes of per cpu data
-Built 1 zonelists in Node order, mobility grouping on. Total pages: 255875
+PERCPU: Allocating 65560 bytes of per cpu data
+cpu with no node 2, num_online_nodes 1
+cpu with no node 3, num_online_nodes 1
251257
"cpu with no node 2" is actually saying that cpu 2 has no node and the
message is a just misleading. The number of online nodes and cpu mappings
are not adding up as I got this from a debugging patch
I'll take a closer look though I've not been able to duplicate your
error yet. It does appear from the message text that the code is
out-of-date. The latest "setup_per_cpu_areas()" should say:

"cpu %d has no node, num_online_nodes %d\n",
i, num_online_nodes());

There are a number of backed up patches in the queue. I'm resubmitting
the whole set re-based on 2.6.25-rc1 shortly. (I don't know though, that
any will address this problem.)

Thanks,
Mike

Online nodes
o 0
CPU <-> node mappings (cpu_to_node)
o CPU 0 -> 0
o CPU 1 -> 0
o CPU 2 -> 1
o CPU 3 -> 1
As the failing code in __alloc_pages() is;
z = zonelist->zones; /* the list of zones suitable for gfp_mask */
if (unlikely(*z == NULL)) {
it implies that an attempt is been made to use an uninitialised zonelist.
If I bodge cpu_to_node() to returning 0,the machine boots but I didn't
see an obvious candidate in origin.patch for the root-cause when I looked
around. I'll bisect this in the morning if this is not a known problem
and no one suggests a possibility.

bl6-13 (4-way x86_64 machine) from test.kernel.org is failing to boot recent

I'll take a closer look though I've not been able to duplicate your

i, num_online_nodes());
There are a number of backed up patches in the queue. I'm resubmitting
the whole set re-based on 2.6.25-rc1 shortly. (I don't know though, that
any will address this problem.)
According to git-bisect, the problem patch is below. It doesn't back out
cleanly so I haven't verified for sure the bisect is correct yet.

x86: change size of APICIDs from u8 to u16

Change the size of APICIDs from u8 to u16. This partially
supports the new x2apic mode that will be present on future
processor chips. (Chips actually support 32-bit APICIDs, but that
change is more intrusive. Supporting 16-bit is sufficient for now).

Signed-off-by: Jack Steiner <***@sgi.com>

I've included just the partial change from u8 to u16 apicids. The
remaining x2apic changes will be in a separate patch.

In addition, the fake_node_to_pxm_map[] and fake_apicid_to_node[]
tables have been moved from local data to the __initdata section
reducing stack pressure when MAX_NUMNODES and MAX_LOCAL_APIC are
increased in size.

This might make sense. This code is in preparation for the extended
apic's available on the new processors. I've tested the code with
our simulator (with no errors) and I'm setting up to test on a real
machine that has multiple numa nodes. I wonder if maybe BIOS is not
providing correct node data, or the ACPI parsing is in error? You
might try adding "apic=debug" to the boot command line.

For the short term, we can remove this patch if it's causing the
problem. A more complete patch will be available soon that contains
the entire set of x2apic changes.

Thanks,
Mike

bl6-13 (4-way x86_64 machine) from test.kernel.org is failing to boot recent
-mm and mainline trees. I noticed it when testing -mm before rebasing other
patches but the oops on mainline looks the same. The full console log is
below but the important difference between a working and non-working kernel
is the following
-PERCPU: Allocating 62512 bytes of per cpu data
-Built 1 zonelists in Node order, mobility grouping on. Total pages: 255875
+PERCPU: Allocating 65560 bytes of per cpu data
+cpu with no node 2, num_online_nodes 1
+cpu with no node 3, num_online_nodes 1
251257
"cpu with no node 2" is actually saying that cpu 2 has no node and the
message is a just misleading. The number of online nodes and cpu mappings
are not adding up as I got this from a debugging patch
I'll take a closer look though I've not been able to duplicate your
error yet. It does appear from the message text that the code is
"cpu %d has no node, num_online_nodes %d\n",
i, num_online_nodes());
There are a number of backed up patches in the queue. I'm resubmitting
the whole set re-based on 2.6.25-rc1 shortly. (I don't know though, that
any will address this problem.)
According to git-bisect, the problem patch is below. It doesn't back out
cleanly so I haven't verified for sure the bisect is correct yet.
This might make sense. This code is in preparation for the extended
apic's available on the new processors. I've tested the code with
our simulator (with no errors) and I'm setting up to test on a real
machine that has multiple numa nodes. I wonder if maybe BIOS is not
providing correct node data, or the ACPI parsing is in error? You
might try adding "apic=debug" to the boot command line.
I tried this, but the dmesg complained about a malformed option. I'll
check out why tomorrow but it didn't appear particularly helpful.
Post by Mike Travis
For the short term, we can remove this patch if it's causing the
problem. A more complete patch will be available soon that contains
the entire set of x2apic changes.
If you send me patches to apply on top of 2.6.25-rc1, I'll give them a spin
on the machine in question. Reverting didn't work out very well as there are
too many collisions with patches that were applied later. I eventually got
the machine booting but it only succeeds because it only brings up one core
on each processor. The patch, which is pretty brain damaged is below in case
it helps you guess what the real problem is. dmesg logs are attached of the
vanilla failure with acpi=debug and the log with the patch applied showing
"__cpu_up: bad cpu 1" and "__cpu_up: bad cpu3" (i.e. the second cores of
each machine).

Well, after lot's of aggravation I finally got the dusty old
numa box to boot up, and the upstream linux-2.6 kernel works fine.
(I've attached the startup log showing 8 cores on 4 nodes.)

The big difference appears in where memory is located. Your
box has all the memory on node 0 where my box has memory on
all the nodes...
SRAT: PXM 0 -> APIC 0 -> Node 0
SRAT: PXM 0 -> APIC 1 -> Node 0
SRAT: PXM 1 -> APIC 2 -> Node 1
SRAT: PXM 1 -> APIC 3 -> Node 1
SRAT: PXM 2 -> APIC 4 -> Node 2
SRAT: PXM 2 -> APIC 5 -> Node 2
SRAT: PXM 3 -> APIC 6 -> Node 3
SRAT: PXM 3 -> APIC 7 -> Node 3
SRAT: Node 0 PXM 0 0-a0000
SRAT: Node 0 PXM 0 0-e4000000
SRAT: Node 0 PXM 0 0-200000000
SRAT: Node 1 PXM 1 200000000-400000000
SRAT: Node 2 PXM 2 400000000-600000000
SRAT: Node 3 PXM 3 600000000-800000000
SRAT: PXM 0 -> APIC 0 -> Node 0
SRAT: PXM 0 -> APIC 1 -> Node 0
SRAT: PXM 1 -> APIC 2 -> Node 1
SRAT: PXM 1 -> APIC 3 -> Node 1
SRAT: Node 0 PXM 0 0-40000000

The message that cpu's 2 & 3 having no node is therefore misleading, it
should say that cpu's 2 & 3 have no "node local memory". But other
than that, it should allocate the PERCPU memory on node 0 and
everything's fine.

Apparently then the only way to debug this is to fake a setup where
some cpus have no node local memory and go from there. Unfortunately,
the box I'm testing on has no working remote access. I'll see if I
can't fake it out on a non-numa box until the lab is back open on Tuesday.

Thanks,
Mike

If you send me patches to apply on top of 2.6.25-rc1, I'll give them a spin
on the machine in question. Reverting didn't work out very well as there are
too many collisions with patches that were applied later. I eventually got
the machine booting but it only succeeds because it only brings up one core
on each processor. The patch, which is pretty brain damaged is below in case
it helps you guess what the real problem is. dmesg logs are attached of the
vanilla failure with acpi=debug and the log with the patch applied showing
"__cpu_up: bad cpu 1" and "__cpu_up: bad cpu3" (i.e. the second cores of
each machine).
This should completely undo the change to 16 bit apic ids until we can figure
out the problem with the memory-less nodes. I checked it on both the numa
and non-numa x86_64 box.

Thanks,
Mike

Hi Mel,

Did you get a chance to try out this patch to see if it cleared up the problem
booting on your x86_64 numa box?

Thanks,
Mike

I initially missed the patch in the bomb of mail that came through over
the weekend, sorry. The machine still fails to boot with this patch
applied. dmesg is below but it looks like essentially the same failure.
I'm offline from tomorrow for a week as well so won't be able to test
another version until I'm back properly :(

If you send me patches to apply on top of 2.6.25-rc1, I'll give them a spin
on the machine in question. Reverting didn't work out very well as there are
too many collisions with patches that were applied later. I eventually got
the machine booting but it only succeeds because it only brings up one core
on each processor. The patch, which is pretty brain damaged is below in case
it helps you guess what the real problem is. dmesg logs are attached of the
vanilla failure with acpi=debug and the log with the patch applied showing
"__cpu_up: bad cpu 1" and "__cpu_up: bad cpu3" (i.e. the second cores of
each machine).
This should completely undo the change to 16 bit apic ids until we can figure
out the problem with the memory-less nodes. I checked it on both the numa
and non-numa x86_64 box.
Thanks,
Mike
Hi Mel,

I initially missed the patch in the bomb of mail that came through over
the weekend, sorry. The machine still fails to boot with this patch
applied. dmesg is below but it looks like essentially the same failure.
I'm offline from tomorrow for a week as well so won't be able to test
another version until I'm back properly :(
Ok, thanks, I'll continue looking into it. Unfortunately, the system I am
testing on does not have remote access working. I'll be over in MV again
tomorrow to try out some things. In the meantime, I'm trying to fake a
node with zero memory to see if that duplicates the problem.

Thanks,
Mike

If you send me patches to apply on top of 2.6.25-rc1, I'll give them a spin
on the machine in question. Reverting didn't work out very well as there are
too many collisions with patches that were applied later. I eventually got
the machine booting but it only succeeds because it only brings up one core
on each processor. The patch, which is pretty brain damaged is below in case
it helps you guess what the real problem is. dmesg logs are attached of the
vanilla failure with acpi=debug and the log with the patch applied showing
"__cpu_up: bad cpu 1" and "__cpu_up: bad cpu3" (i.e. the second cores of
each machine).
This should completely undo the change to 16 bit apic ids until we can figure
out the problem with the memory-less nodes. I checked it on both the numa
and non-numa x86_64 box.
Thanks,
Mike
Hi Mel,
Did you get a chance to try out this patch to see if it cleared up the problem
booting on your x86_64 numa box?
did it fail with x86.git#testing?

Hi,

My problem is that I haven't been able to set up a NUMA box where some of the nodes
have no memory. The one box we have, the serial port doesn't work and it's in a lab
far, far away. Everything else, it works fine.

x86.git#testing should be solid with numa and nodes without memory.

No, it boots successfully with that git branch. Somewhere in there is a fix.

x86_64: not set node to cpu_to_node if the node is not online

numa_init_array will set round-bin to all cpu to online nodes.
init_cpu_to_node will use cpu->apic (from MADT or mptable) and
apic->node(from SRAT or AMD config space with k8_bus_64.c) to have cpu->node mapping.
and later identify_cpu will overwrite them again...(with nearby_node...)

this patch will check if the node is online, otherwise will not update cpu_node map.
so keep cpu_node map to online node before identify_cpu..., to prevent possible error.

x86_64: not set node to cpu_to_node if the node is not online
thanks - so should we accelerate this into v2.6.25?

I believe it needs to be merged for v2.6.25. According to test.kernel.org,
bl6-13 is failing boot tests in mainline so it's either this or a lot of
reverting.
