linux-next: Tree for August 15

linux-next: Tree for August 15

[Stephen Rothwell]

[-- Attachment #1: Type: text/plain, Size: 7945 bytes --]

Hi all,

Changes since next-20080814:

New trees: oprofile and fastboot.

The tip-core tree lost its conflict.

The cpus4096 tree lost its conflict.

The ftrace tree gained a conflict against the driver-core tree and a
build failure required the revert of a commit.

The stackprotector tree gained a conflict against the ftrace tree.

The x86 tree gained a conflict against the stackprotector tree but lost
two conflicts and a build fix patch.

The kvm tree gained a conflict against the x86 tree.

The test tree gained a conflict against the sched tree.

The kmemcheck tree gained two conflicts against the x86 tree.

The hdlc tree lost its build fix patch.

The creds tree gained a conflict against the ftrace tree (and several
against Linus' tree - but they were expected).

The fastboot tree gained a conflist against the driver-core tree.

I have also applied the following patches for known problems:

	Add cuImage.mpc866ads to the bootwrapper as a cuboot-8xx target
	ath9k: work around gcc ICE again
	driver-core: don't export static functions

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

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, it is also built with powerpc allnoconfig,
44x_defconfig and allyesconfig and i386, sparc and sparc64 defconfig.

Below is a summary of the state of the merge.

We are up to 110 trees (counting Linus' and 14 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.

When VLAN is not enabled, bnx2 build fails with:

drivers/net/bnx2.c: In function 'bnx2_rx_int':
drivers/net/bnx2.c:2959: error: dereferencing pointer to incomplete type

on these lines:

Whoops, my fault, now fixed; thanks!

Yes, it does.  Thanks.

Actually I hit the related Oops with the latest linux-next tree.
Since this bug appears first on that tree and didn't occur on the
previous tree, it was apparently a regression.  So, I looked through
changes over knfsd since the previous tree, found a suspicious one,
and tried to fix.

The linux-next tree is pretty helpful to catch a regression if one
eats own dog foods everyday.

BTW, I've been building linux-next SUSE kernel packages at every
linux-next release.  The packages are found in the following URL:

    http://ftp.suse.com/pub/people/tiwai/kernel-next/

If anyone has a SUSE system and would like to try linux-next kernel,
just installs the package in addition.  It won't conflict with
existing standard kernel packages.


thanks,

Takashi

Hi,

where can I see where all the branches com from, especially fastboot?
The wiki is somewhat outdated regarding the "IncludedTrees" page.

OK, now I see my problem: my test systems deliver the rest of their
results by email, but if I want to check the logs for oops messages I
still need to remember to log in and look after each test run.  So I got
lazy and missed the slab errors on nfsd shutdown.

I wonder what the easiest way would be to automate collection of oops
messages from the logs?  I suppose I should look at what the code that
submits to kerneloops.org does.
