Those were examples, we already have cases where blocks are shared across

The ARM use case is already there, today.

Did you even bother looking at the files and how they are used? We are
not going to duplicate identical files for each architecture.

You seem to be ignoring the fact that we've had these use cases for years
already and that the current scheme has so far served us pretty well in
that regard. If we have headers for drivers that are used across multiple
architectures, then include/linux is ultimately the proper place for
them. We could shoe-horn them in to some sort of pseudo-architecture
thing in include/ but for what purpose?

Until you've actually read through the background mail on this and
actually looked at the code in question I see very little point in
continuing this thread. I'm of course open to suggestions on how to make
this sort of abstraction cleaner, but so far none of your suggestions are
relevant to the problem at hand.
