This should be a separate patch.

Ditto.

Ditto...

Do you see where I'm going with this?

Each patch should countain one logical change: add defines and move
struct, change functionality A, change functionality B, ...

The fact that you have to make a list of 8 important changes should
already give you a hint that it needs to be split.

As always, I'm going to need ACKs for the ARM stuff.
