Heiko Carstens d2b1f6d2d3 s390/cmpxchg: 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. This basically reverts commit f318a1229b ("s390/cmpxchg: use compiler builtins"). Signed-off-by: Heiko Carstens <hca@linux.ibm.com>		2021-04-12 12:46:43 +02:00
