Hi all,
Changes since 20101111:
The voltage tree lost its build failure.
The fsnotify tree lost its build failure.
The tty tree gained a build failure for which I reverted a commit.
----------------------------------------------------------------------------
I have created today's linux-next tree at
git://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git
(patches at http://www.kernel.org/pub/linux/kernel/v2.6/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 - this fails its final link) 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 179 trees (counting Linus' and 26 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 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.

Thanks, applied.
BTW, Doug, we still carry the bluesmoke-devel ML as edac mailing list
in MAINTAINERS althouth there's a new linux-edac@vger... which got
proposed recently. I think we should use that new one and deprecate the
sourceforge list since the new one is not moderated for subsribers and
thus more open.
Thoughts?

We need the SCU so in fact we really want to select that. I'll send a
patch to Ingo.

Ah, OK, thanks. I was wondering what the proper fix for this was. I'll
stick this in my tree.
