Ilya Leoshkevich ba3b86b9ce s390/bpf: Implement new atomic ops ... Implement BPF_AND, BPF_OR and BPF_XOR as the existing BPF_ADD. Since the corresponding machine instructions return the old value, BPF_FETCH happens by itself, the only additional thing that is required is zero-extension. There is no single instruction that implements BPF_XCHG on s390, so use a COMPARE AND SWAP loop. BPF_CMPXCHG, on the other hand, can be implemented by a single COMPARE AND SWAP. Zero-extension is automatically inserted by the verifier.
