Heiko Carstens b23eb636d7 s390/atomic: get rid of gcc atomic builtins ... s390 is the only architecture in the kernel which makes use of gcc's atomic builtin functions. Even though I don't see any technical problem with that right now, remove this code and open-code compare-and-swap loops again, like every other architecture is doing it also. We can switch to a generic implementation when other architectures are doing that also. See also https://lwn.net/Articles/586838/ for forther details.
