Hi Krzysztof,

as mentioned before, all arch/arm/mach-* patches should go through the
arm-soc tree or get an Ack from the arm-soc maintainers. The same thing
is true for the char-misc and the crypto trees.

Also, never rebase your tree immediately before sending a pull request.
The preferred way is to have everything based on the -rc release that
is the latest one at the time when you do your testing. If you rebase
later, you essentially have to test everything again.

Finally when sending bug fixes, please annotate any patches with
'Cc: stable@vger.kernel.org' if they address bugs that are already
present in older kernels, so that the stable and longterm maintainers
can easily backport the fixes.

Almost all of the platform patches in your tree seem to be bug fixes,
so they are still good for inclusion in v3.7 if you submit them to
arm-soc soon, but please make sure you separate bug fixes from other
changes so we can group them appropriately when forwarding them to
Linus.

Thanks,

	Arnd

You've seen the changes. They were trivial fixes, touched only
IXP4xx-related areas, there was nothing related to char or crypto
subsystems there, except file location (well, IXP4xx drivers have to be
located somewhere).

The patches have been posted to linux-arm-kernel and you knew about
them. That they were obviously correct and clean is probably not
that important.

Nobody bothered to comment the patches.

> Also, never rebase your tree immediately before sending a pull

I did not, of course. My mail stated:
"Build-tested for now. This is based on your current tree tip because it
depends on commits following 3.6 release."

Normally I wouldn't rebase, but had to (as you well knew) - because you
commited a conflicting patch to this very IXP4xx arch. Using your logic,
you were supposed to get an Ack from me (or from Imre) for this patch.

Actually it wasn't a problem for me, I simply had to rebase.

I do that when I think it makes sense. In this case (two patches for
Goramo MultiLink platform) practically all such devices use kernels
prepared by me, and I think Greg (and others) have more efficient ways
to spend their time than handling almost unused patches. Also, I have
much more efficient ways to spend time. Anyway, if I can't have my
patches upstream, why should they end up in stable?

Unfortunately, as I already explained to you in
https://lkml.org/lkml/2012/9/29/37, my resources for IXP4xx are very
limited (and this isn't a paid job) and I'm in no way able to do what
you require. This, coupled with my inability to make the patches end up
upstream any other way, will make me post relevant MAINTAINERS changes
shortly.

Don't get me wrong. If I had time for this it could be different.
Unfortunately IXP4xx is a legacy arch, and for me it's simply a hobby at
this point. Given the raised barriers to participate, probably aimed at
paid maintainers, I have to quit doing this.

BTW since Imre has probably even much less time, it would be a good time
to find someone to maintain IXP4xx code. I will be publishing (from time
to time) my tree (I'm using the hw myself), so even simple
cherry-picking would probably make some sense.

Krzysztof, please reconsider.  I'm also a hobbyist maintainer
(kirkwood,orion5x,mv78xx0,dove,mvebu).  I'd hate to see the community
lose a valuable maintainer because arch/arm/ has grown so much.

If you would like, I could pull your patches through my tree and send
them on to arm-soc.  I'm already familiar with arm-soc process, and I'll
admit I have a soft spot for mach-ixp4xx.  It was my first experience
with embedded Linux (nslu2, gateworks boards).

This way, you could see the process first hand without having to do the
labor.

We could do this for a few release cycles so you can see how it goes.
After that, we can reassess things.  If you still don't wish to lend
your experience, so be it.  But I hope we can change your mind.

thx,

Jason.

So if no one else wants to do this, then I am willing to look after
the IXP code. I think that I do have the time for it.

You're lucky that you didn't get flamed by Linus himself for that, as
others _have_ been in the past.

If you had *bothered* asking the arm-soc people to pull your tree
_instead_ of Linus, then that problem becomes the arm-soc's problem, not
yours.  That  means _you_ end up with _less_ work to do.  Yet, instead
of seeing that benefit, whenever you've been asked to send your tree via
arm-soc, you throw your toys out of your pram and basically refuse.

So, you're making *more* work for yourself by not participating in
arm-soc (as I've explained to you before.)

The _ONLY_ thing you have to do is send your pull request to the arm-soc
people instead of Linus before the merge window opens.  You don't need to
rebase your stuff on a different tree, you can still use Linus' tree as
a basis.

You have offered no technical reason why you can't participate in arm-soc
which has stood up to screutiny.

The only reasons you've offered seem to be:

1. it'll be more work (untrue)
2. you look after platforms which aren't in mainline and you're not submitting
   to mainline.

Both of these a total nonsense arguments when it comes to the _route_ that
your patches make their way into mainline.  They have absolutely no bearing
on the path your changes take AT ALL.

As you're being difficult and not willing to co-operate, and for whatever
reason building this issue into a mountain, this unfortunately sounds to
me like a good thing.  Hopefully, a more co-operative maintainer will step
up in your place who can see the benefits.

I maintain a tree for the ep93xx, which is another legacy arm soc. I
also do this as a hobbyist, not as a paid position. Pushing patches to
mainline via arm-soc has been very easy. Basically I branch from Linus's
tree (typically 3.x-rc1), apply patches to one of a bunch of branches
(-devel, -fixes, etc) and then send pull requests to the arm-soc
maintainers prior to the merge window. I also have a aggregate branch
which is tested in next.

It takes very little of my time to maintain this tree. I cannot see how
it could be any harder than sending to Linus directly. Also, the arm-soc
maintainers, Arnd and Olof, have been very helpful in getting me started
with my maintainer tree, and in learning the development flow.

I would also rather get flamed by the arm-soc guys than Linus when I
make a mistake :-).

Thanks for the offer! 

Jason Cooper was also volunteering to help out with this, and even we can't
convince Krzysztof to continue doing it, there is also Imre who is officially
listed as maintainer for IXP4xx and who has not commented on this. As Krzysztof
mentions, he probably doesn't have much time for it, but I'd like to give
him the chance to comment as well.

I'm sure we can find some solution between the four of you. Right now, I think
we should focus on getting the bug fixes from Krzysztof's tree into mainline
and the stable kernels where applicable, and then establish a better working
mode for the future kernels.

Agreed.

We also need to keep an eye on the big picture.  If we are going to
keep/maintain ixp4xx in the kernel, there are some things which need to
be done.  The drivers need moved to drivers/, platform headers need
moved to platform_data/, and we may as well add devicetree bindings
while we're moving things around.

Making ixp4xx compatible with multiplatform zImage would probably help
out the embedded distros as well.

thx,

Jason.
