- Something in linux-next has broken my X server

- My Vaio is vacationing on the other side of the continent. Ignorance
is bliss.

- Lots of people are vacationing at present (certain x86 people, for
example). I'll still be around so please be sure to Cc me on things.

But I am unlikely to want to be buried in x86 patches, so please just
give those an extra week or two's testing.


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.

Andrew,

Please don't do so. We did discuss this and while Paul and Hugh have
opposed the patches, there is no alternative to memory overcommit
handling for cgroups. Claiming that no one supports overcommit is not
a valid argument. Apache (of what I've seen can decide rlimits for
each of it's children). Without the overcommit feature, a cgroup would
be prone to either excessive swapping for OOM (if badly configured). A
friendly feature that allows us to control and fail allocations is
much nicer.

I've resolved most of the issues reported, except for the last one by
Hugh. The infrastructure also allows me to build a mlock controller. I
am just back from Canada, I hope to get cracking at the problem soon.

Hi Andrew,
make allyesconfig with 2.6.27-rc1-mm1 kernel on powerpc fails with build error
<snip>

Turning off GCOV "fixes" this. Not really the best solution but at
least it narrows doen the search effort.

Peter,
Can you have a look at how this can be fixed, if at all?

Am not terribly happy with the state of the gcov patches. They STILL
leave thousands of dead symlinks lying around after `make mrproper' and
generally seem to muck up the kbuild system a bit, although nothing
that a bit of Sam love wouldn't fix.

Plus it breaks the build on a few architectures (branch out of range,
mainly), but that's a fairly minor thing which could even be worked
around in Kconfig (disable the offending code if gcov is enabled)

This is caused by patch

gcov-create-links-to-gcda-files-in-build-directory.patch

which can be simply removed as it is no longer needed since patch

gcov-add-gcov-profiling-infrastructure-revert-link-changes.patch

has been added to -mm.

Hm, by now the only change to kbuild is the addition of gcc options
-fprofile-arcs/-ftest-coverage depending on the respective config
symbols. If there is anything else that should be changed, please
let me know.

Some of the problems caused/uncovered by enabling gcov profiling for
a kernel build on some architectures simply cannot be fixed by a change
to the kernel patch itself. I'm wondering if it would be possible
to disable this configuration option when specifying allyesconfig. That
way at least generic testing wouldn't be affected.

Have not had time / energy to get aroud to it.
Other things continue to pop up and time is limited at the moment

I did some testing with a cross-compiler myself and I don't think
there is a general solution to this problem. It's not one particular
file that is causing the problem but seemingly the sheer size of the
resulting vmlinux file - even though the toal vmlinux.o size is
"merely" up about 100MiB (from around 1,03Gib to 1,13Gib).

I think I'll need help from people with knowledge of the powerpc
toolchain here.

Thanks for debugging this. I see the problem now: previous reference
counting fix was totally fscked up and introduced access to cd->drive
after putting last reference on cd (time to re-supply brown paper bag
stock). The incremental fix (for 2.6.27-rc1-mm1) attached, the fixed
original patch will be posted in the separate mail.

2) on drive->hwif->host->dev[0] (->dev is bogus?)
Does it still happen with the 1) fixed?

No. I applied your incremental fix and tested it for some time. It doesn't
oops anymore in any way in spite of my best efforts :)

I'm running preemtible kernel and have seen similar things before:
http://marc.info/?l=linux-kernel&m=120652827627051&w=2 and it was fixed by disabling
preemtpion in relevant sparc64 code paths. smp_call_function_mask() documentation
says it must be called with preemption disabled.

Here is a similar fix. Compile and run tested.

Here is a similar fix. Compile and run tested.
Thenk for the report and sample patch.

I've decided to put the preemption disabled call at the smp_tsb_sync() call
site so that smp_tsb_sync() can still invoke smp_call_function_mask() as
a tail-call.

Thanks again!

sparc64: Need to disable preemption around smp_tsb_sync().

Based upon a bug report by Mariusz Kozlowski

It uses smp_call_function_masked() now, which has a preemption-disabled
requirement.

Hello Peter,

I'm seeing similar GCOV problems as with 2.6.26-rc5-mm1 that you fixed.
This is the same x86_64 box and again it was unable to boot with gcov enabled.
A quick look revealed that arch/x86/tsc_64.c and arch/x86/tsc_32.c code was
unified. Unfortunately simple change of

GCOV_tsc_32.o := n
GCOV_tsc_64.o := n

to

GCOV_tsc.o := n

did not help. Given the amount of combinations of which set of files with GCOV
might cause failures I was rather fortunate and after a few hours I was able
to pinpoint exactly two files which need GCOV disabled to make my x86_64 boot.

If you want to try to figure out what is wrong with them please feel free to send
me patches to test. If not then how about this patch? Compile and run tested.

Hello Peter,
I'm seeing similar GCOV problems as with 2.6.26-rc5-mm1 that you fixed.
This is the same x86_64 box and again it was unable to boot with gcov enabled.
A quick look revealed that arch/x86/tsc_64.c and arch/x86/tsc_32.c code was
Make that arch/x86/kernel/tsc_64.c and arch/x86/kernel/tsc_32.c

I'm seeing similar GCOV problems as with 2.6.26-rc5-mm1 that you fixed.
This is the same x86_64 box and again it was unable to boot with gcov enabled.
A quick look revealed that arch/x86/tsc_64.c and arch/x86/tsc_32.c code was
unified. Unfortunately simple change of
GCOV_tsc_32.o := n
GCOV_tsc_64.o := n
to
GCOV_tsc.o := n
did not help. Given the amount of combinations of which set of files with GCOV
might cause failures I was rather fortunate and after a few hours I was able
to pinpoint exactly two files which need GCOV disabled to make my x86_64 boot.
If you want to try to figure out what is wrong with them please feel free to send
me patches to test. If not then how about this patch? Compile and run tested.
Your patch looks good. I don't think I will be able to refine those
list of files to be excluded any better than you already did so this
should go into -mm with the other gcov patches.

For future reference, there are other object files which "stand out" in
the respective Makefile, namely rtc.o, hpet.o and paravirt.o. Just like
the two files that you identified as causing problems with gcov
profiling, these are explicitly excluded from either FTRACE profiling
or stack-protector checks or both. If there should be further run-time
problems, these are good candidates to check, though I'd like to refrain
from removing them at this point in time without them causing any
apparent problems.


Regards,
Peter
