Subject: linux-next: Tree for March 30

Hi all,

Changes since 20090327:

Various conflicts have moved around due to some trees being merged into
Linus' tree.

Linus' tree gained a build failure for which I applied a patch.

The arm tree lost its three conflicts.

The tracing tree inherited a build failure from the net tree.

The genirq tree lost its conflict.

The sched tree lost its conflict.

The v4l-dvb tree lost its build failure.

The acpi tree gained a conflict against Linus' tree but lost its build
failure.

The ext4 tree lost its conflict.

The net tree lost all its conflicts.

The rr tree lost 8 conflicts.

The slab tree lost all its conflicts.

The drm tree lost its conflict.

The lblnet tree lost its conflicts.

The proc tree gained a build failure due to a new commit in Linus' tree -
I applied a patch.

The suspend tree lost its conflict.

----------------------------------------------------------------------------

I have created today's linux-next tree at
git://git.kernel.org/pub/scm/linux/kernel/git/sfr/linux-next.git
(patches at
http://www.kernel.org/pub/linux/kernel/people/sfr/linux-next/). If you
are tracking the linux-next tree using git, you should not use "git pull"
to do so as that will try to merge the new linux-next release with the
old one. You should use "git fetch" as mentioned in the FAQ on the wiki
(see below).

You can see which trees have been included by looking in the Next/Trees
file in the source. There are also quilt-import.log and merge.log files
in the Next directory. Between each merge, the tree was built with
a ppc64_defconfig for powerpc and an allmodconfig for x86_64. After the
final fixups (if any), it is also built with powerpc allnoconfig (32 and
64 bit), ppc44x_defconfig and allyesconfig (minus
CONFIG_PROFILE_ALL_BRANCHES) and i386, sparc and sparc64 defconfig.
These builds also have CONFIG_ENABLE_WARN_DEPRECATED,
CONFIG_ENABLE_MUST_CHECK and CONFIG_DEBUG_INFO disabled when necessary.

Below is a summary of the state of the merge.

We are up to 133 trees (counting Linus' and 18 trees of patches pending for
Linus' tree), more are welcome (even if they are currently empty).
Thanks to those who have contributed, and to those who haven't, please do.

Status of my local build tests will be at
http://kisskb.ellerman.id.au/linux-next . If maintainers want to give
advice about cross compilers/configs that work, we are always open to add
more builds.

Thanks to Jan Dittmer for adding the linux-next tree to his build tests
at http://l4x.org/k/ , the guys at http://test.kernel.org/ and Randy
Dunlap for doing many randconfig builds.

There is a wiki covering stuff to do with linux-next at
http://linux.f-seidel.de/linux-next/pmwiki/ . Thanks to Frank Seidel.

the fault is reproducible and happens some seconds after having

Yes, the .config would be useful. I'm mainly interested in which slab
allocator you are using. I'm testing kmemleak mainly on ARM and haven't
seen any issues.

Thanks.

attached is the .config for linux-next 20090401, which should be
roughly the same than the 20090330 one.

some hours ago i booted the board with 20090401 and the page fault
didn't happen

Do you still get this fault with the latest linux-next? I can't
reproduce it on my ARM platform (I tried it with the latest mainline
kernel as well).
