It seems there is nothing really stopping all of them to take pointer to const. Patchset was really tested on all affected architectures. 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. All other can go separately after these get merged.
