Yes, it is the big 3.0 coming to a Linaro server near you !
The Linux v3.0 based Linaro kernel branch is now available from:
http://git.linaro.org/gitweb?p=kernel/linux-linaro-3.0.git%3Ba=summary
http://git.linaro.org/git/kernel/linux-linaro-3.0.git
Since the official final v3.0 from Linus Torvalds is going to happen in a matter of hours now, and considering that the freeze for the 11.07 kernel release is supposed to take effect this Thursday, this is probably the best time to fork the Linaro-3.0 branch and start merging patches onto it. Currently this contains the following from RMK's devel-stable branch:
* The comprehensive ARM kprobes work from Jon (Tixy) Medhurst
* The new processor struct macros from Dave Martin
* A small part of the single zImage work from myself
* The ARM cpu topology definition from Vincent Guittot
* Basic Cortex A5 support from Will Deacon & Pawel Moll
* DMA infrastructure cleanups from Russell King
* A kernel helper to perform 64-bit atomic operations from myself
Please let me know if you want to see something merged into the linaro-3.0 tree before Thursday.

Well, in theory, I guess you could just merge all of the current arm-soc/for-next contents, which would help get some more testing on the patches that go into 3.1.
If you think that's too adventurous, it's probably good to merge at least the next/fixes branch. The next/fixes2 branch contains all the omap bug fixes, because they depend on the omap cleanup patches.

Great... I established a rebase branch "tilt-linux-linaro-3.0"
http://git.linaro.org/gitweb?p=people/andygreen/kernel-tilt.git%3Ba=shortlog...
which is our goodies based on this.
However I noticed a small problem in ALSA core, it's either come from linus tree in the last day or from the merges in linux-linaro-3.0

You can pull devicetree/next right now. I've still got a few things to do before I get you to pull the dt board support patches. Give me a few more hours.

No problem. I can wait until I go to bed.
Okay, I'm spinning up the tree now. I don't have an ack yet from tglx on the irq_domain, so they won't be the *exact* commits that go into linus' tree, but they will be close.
I'm assuming that you've already got the zImage dtb append patches, and that you've taken care of getting them into linux-next.

Actually, I'm not pushing it upstream yet as I'm not satisfied with some parts of the ATAG to DT support. But I'll merge what I have now in the linaro-3.0 tree.

So I'm working on merging this into the Android tree and something in your tree is causing Pandaboard to hang very early at boot:
Starting kernel ...
Uncompressing Linux... done, booting the kernel.
... And that's all.
I rolled back to just your tree and got the same thing (the vanilla Android 3.0 branch still works fine).
Attached is the config I was testing with.
I'll be trying to debug and bisect this down further, but has anyone else been testing the Linaro kernel on Panda?

So I'm working on merging this into the Android tree and something in your tree is causing Pandaboard to hang very early at boot:
Starting kernel ...
Uncompressing Linux... done, booting the kernel.
... And that's all.
I rolled back to just your tree and got the same thing (the vanilla Android 3.0 branch still works fine).

Bisecting narrowed it down to: af496a67c101b2161a12c1bc70626f6a479501bb
Arnd: Maybe something went badly with the merge collision resolution there?
And frustratingly, since its a merge commit, I can't just revert that one commit.
Is anyone else testing Nico's tree (or even the ARM-SOC tree) with PandaBoard?
According to the following from today, the merge should not have happened in the first place. Nico, do you need to rebase/merge with latest arm-soc/for-next tree?

OK, my fault, I missed that. Obviously I should not have taken that merge given its uncertainty. So I reverted it.
[...]
And... the latest arm-soc/for-next branch is giving me yet more conflicts in the imx and omap code. I'm not in a position to resolve those this close to the freeze deadline. Too bad: I'm not merging it at all.
