Re-read the last link you quoted, and especially this part:

While your patch goes in the good direction, it doesn't mean it is
correct. Conditionally compiling code on CONFIG_BSD in a Linux specific
file doesn't make sense.
I am pretty fine applying a correct patch if you send a new one.

I have no problem with you having no interest in sh4, a lot of people
are in you case. I don't think it gives you the right to describe the
sh4 kernel maintainer as "sh4 linux-kernel maintainer officially doesn't
care about anybody who isn't employed by his company", or later "It's
not real hardware, it's a one-company toy". This is not something
reflected in link you quoted. Paul Mundt has been nicely answering your
question on this thread.
