H8/300 has been dead for several years, the kernel for it has
not compiled for ages, and recent versions of gcc for it are broken.
It is time to drop support for it.
Yes, I understand it is not that simple to drop an architecture,
and it may need some discussion, but someone has to put a stake
into the ground. Keeping a virtually dead architecture on life support
takes resources which are better spent elsewhere.

If this doesn't build, and no one is using it anymore, I agree, it
should be removed. If someone wants to revive it, 'git revert' works
just fine.
You can put my:

on these patches, unless someone steps up to be the active maintainer of
the arch and gets it building/working again.

Agree. You may add my Acked-by.
How do you plan to get this upstream? Do I need to take the watchdog in my tree or do you plan to keep the set of patches together in one tree?
Kind regards,
Wim.

My plan is create a branch on my repository on kernel.org, ask Stephen
to add it to linux-next, and then ask Linus to pull it after one
release cycle (ie for 3.13). This should give people enough time
to find out about it and complain, and give everyone else enough time
to find any missing pieces.
I would not mind if Linus would agree to pull it right away for 3.12,
but that seems to be a bit on the fast side.
Thanks,
Guenter

I'm ok with code deletion patches, I don't think that would be a
problem. I didn't check them, but I assume this is all literally just
removing code that is conditional on h8/300 config options?

Yes.
I found a couple more since I sent the series, but nothing significant.
What is your preference - keep it until 3.13, or prepare it now and send you
a pull request for 3.12 ?

It would be nice to check with Sato-san, who wanted to attend Kernel
Summit as a hobbyist architecture maintainer, and see what are his plans
and opinions.
