Someone would need to take care of it and document it and repair all
those driver which broke because they went and created private copies.
I could do some of that but I'm stuck at step #1. What the heck _are_
these things? Why do they exist? What are their semantics?
The arm implementation says
* Generic IO read/write. These perform native-endian accesses. Note
* that some architectures will want to re-define __raw_{read,write}w.
which is somewhat clear as mud. I'd guess that these are the MMIO
partners to insl and friends?
And then it has
extern void __raw_writesb(void __iomem *addr, const void *data, int bytelen);
extern void __raw_writesw(void __iomem *addr, const void *data, int wordlen);
extern void __raw_writesl(void __iomem *addr, const void *data, int longlen);
which is a bit odd. I assume that "bytelen" should have been
"bytecount" or similar.
