IBM still put 40x cores inside POWER chips no ?

Oh yeah that's true. I guess most folks don't know that, or that they
run RHEL on them.

Is there a reason for not having those dts files in mainline then?
If nothing else, it would document what machines are still being
used with future kernels.

Sorry that part was a joke :D  Those chips don't run Linux.

Nice to know :)

What's the plan then, do we still want to keep 40x in the kernel ?

I guess we keep it for now.

Perhaps we mark it BROKEN for a few releases and see if anyone
complains?

If yes, is it ok to drop the oldies anyway as done in my series 
https://patchwork.ozlabs.org/project/linuxppc-dev/list/?series=172630 ?

Yeah let's do it. I would love to get rid of that horrible
PPC405_ERR77() sprinkled all through our atomics.

(Note that this series will conflict with my series on hugepages on 8xx 
due to the PTE_ATOMIC_UPDATES stuff. I can rebase the 40x modernisation 
series on top of the 8xx hugepages series if it is worth it)

Yeah if you can rebase that would be great.

cheers
