Hi all,
There will not be another -next tree until April 14 (my time) due to
holidays here.
Changes since 20090408:
This tree will not build a powerpc allyesconfig.
Linus' tree lost 1 build failure.
The usb.current tree lost its build failure.
The tip-core tree gained a build failure on sparc64 for which a applied a
patch.
The block tree gained a build failure so I reverted a commit.
----------------------------------------------------------------------------
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 132 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.

Hi Sachin,
Thanks for warning about this. This error happens only with some gcc versions.
Yet, I'm adding a patch to use do_div() to avoid such troubles. It should be
there for today's linux-next.
Cheers,
Mauro

I had Next 09 booted on a powerpc box and was compiling a kernel.
That's when i ran into this oops.

It has a link failure with i386 allmodconfig due to missing __divdi3.
It's due to this statement in drivers/media/video/cx88/cx88-dsp.c's
int_goertzel():
return (u32)(((s64)s_prev2*s_prev2 + (s64)s_prev*s_prev -
(s64)coeff*s_prev2*s_prev/32768)/N/N);
that gem will need to be converted to use div64() or similar, please.
