Obviously this has to be applied after all the others, so I assume
somebody else will take this.

After one more night, I should have mentionned that the way have removed
"pci-dma-compat.h" may break OTHER drives because of indirect include.
The line above should maybe be replaced by:
#include <linux/dma-mapping.h>
which is hidden in "pci-dma-compat.h".
Will see if built-bots complain.
And so they did.
What is the best option?
1. Add #include <linux/dma-mapping.h>? or
2. Add this "missing" include in needed place?
I would say 2, but I would need help, because I don't have a built farm
at home! :)
This breaks:

I got another built failure that I don't understand:
