The ioread8/16/32() and others have inconsistent interface among the
architectures: some taking address as const, some not.

It seems there is nothing really stopping all of them to take
pointer to const.

Shouldn't all of them take const volatile __iomem pointers?
It seems the "volatile" is missing from all but the implementations in
include/asm-generic/io.h.

It's kind of separate issue although I could squash it to limit
redundant changes.

Patchset was really tested on all affected architectures.

I just spot an error in my first message. I wanted to say:
"Patchset was NOT really tested on all affected architectures."

Obviously.

Build testing is in progress - I hope auto-builders will point any issues.


Todo
====
Convert also string versions (ioread16_rep() etc) if this aproach looks OK.


Merging
=======
The first 5 patches - iomap, alpha, sh, parisc and powerpc - should probably go
via one tree, or even squashed into one.

Yes, they should be squashed, cfr. Arnd's comment.
I also wouldn't bother doing the updates in patches 6-10.

Indeed, thanks for comments.

Best regards,
Krzysztof
