Status of the arm26 port?
I'm wondering what the status of the arm26 port in the kernel is:
AFAIR gcc support for this architecture was deprecated in gcc 3.4 and removed in gcc 4.0. This implies that either someone will have to re-add support to gcc in the next 1-2 years or the kernel port will become useless with the next increase of the minimum gcc requirement for the kernel.
The other point is that I tried to cross-compile an arm26 defconfig. I gave up after running into several compile errors, and it doesn't seem as if any recent kernel could be compiled.
Is the arm26 kernel port already unused dead code or is some work for getting it back into shape pending?

Pearl S. Buck - Dragon SeedRFC: Remove the arm26 port
Considering the state of the arm26 port, I do hereby suggest to remove it from the Linx kernel since it's far from a usable state and doesn't seem to come back into a usable state.
If anyone wants to work on getting this port back into a usable state in the forseeable future he should speak up now.

Yes, please. This bitrotting code has been in the way for quite bit of cross-architecture work I've been doing.
Btw, there's probably no point to Cc rmk as he's not involved with that stinkin' pile.

Definitely - I'd like to see it gone so hopefully I'll stop being copied on every single janitorial change to it.
(And yes, I've re-enabled mail-followup-to since otherwise I can't group-reply in mutt to everyone - without it I just get hch in the To:
header and an empty CC: with 'g'. Tough shit to those anti-mail-followup-to people. It's the only thing that actually works.)

As was being discussed a few weeks ago; the drivers/acorn/block should go at the same time since they are only in ARM 26 machines.

Hi guys.
Obviously I havent had time to work on the port in some time now - I am ok with it being dropped - the work of splitting it out wont be lost and until its fixed up, its just in other peoples way.
If I get time to work on it in future, I'll let you all know.

thanks for your answer.
This email contains the patch to remove the arm26 architecture.
This is neither meant against you nor against the arm26 port, and I don't have any problems if you or anyone else will submit an arm26 port in a working state in the future.

You could've submitted a git patch. Would've been smaller and easier to apply, I think.
