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
