a) chicken and egg: asm-generic/atomic.h depends on definitions in asm/atomic.h
Ok, I see.
If you can find a way to reshuffle the code and make it simpler, I personally am all for it. I'm skeptical that you'll get much to show for the effort.
I guess it could be done using more macros or new headers, but I don't see a way that would actually improve the situation.
b) The definitions aren't precisely identical between all architectures, so it would be a mess of special cases, which gets us right back to where we are now.
Why are they not identical? Anything beyond the 32/64 bit difference should be the same afaics, or it might cause more bugs. Arnd <><
