Somehow this series is missing a cover letter.

While you are touching all this "fun" can you also look into killing
__ioremap?  It seems to be a weird non-standard version of ioremap_prot
(probably predating ioremap_prot) that is missing a few lines of code
setting attributes that might not even be applicable for the two drivers
calling it.
