CONFIG_ATOMIC_OPERATIONS_C:¶
Use atomic operations routines that are implemented entirely in C by locking interrupts. Selected by architectures which either do not have support for atomic operations in their instruction set, or haven’t been implemented yet during bring-up, and also the compiler does not have support for the atomic __sync_* builtins.
