Christophe Leroy 353e7300a1 kcsan: Don't expect 64 bits atomic builtins from 32 bits architectures ... Activating KCSAN on a 32 bits architecture leads to the following link-time failure: LD .tmp_vmlinux.kallsyms1 powerpc64-linux-ld: kernel/kcsan/core.o: in function `__tsan_atomic64_load': kernel/kcsan/core.c:1273: undefined reference to `__atomic_load_8' powerpc64-linux-ld: kernel/kcsan/core.o: in function `__tsan_atomic64_store': kernel/kcsan/core.c:1273: undefined reference to `__atomic_store_8' powerpc64-linux-ld: kernel/kcsan/core.o: in function `__tsan_atomic64_exchange': kernel/kcsan/core.c:1273: undefined reference to `__atomic_exchange_8' powerpc64-linux-ld: kernel/kcsan/core.o: in function `__tsan_atomic64_fetch_add': kernel/kcsan/core.c:1273: undefined reference to `__atomic_fetch_add_8' powerpc64-linux-ld: kernel/kcsan/core.o: in function `__tsan_atomic64_fetch_sub': kernel/kcsan/core.c:1273: undefined reference to `__atomic_fetch_sub_8' powerpc64-linux-ld: kernel/kcsan/core.o: in function `__tsan_atomic64_fetch_and': kernel/kcsan/core.c:1273: undefined reference to `__atomic_fetch_and_8' powerpc64-linux-ld: kernel/kcsan/core.o: in function `__tsan_atomic64_fetch_or': kernel/kcsan/core.c:1273: undefined reference to `__atomic_fetch_or_8' powerpc64-linux-ld: kernel/kcsan/core.o: in function `__tsan_atomic64_fetch_xor': kernel/kcsan/core.c:1273: undefined reference to `__atomic_fetch_xor_8' powerpc64-linux-ld: kernel/kcsan/core.o: in function `__tsan_atomic64_fetch_nand': kernel/kcsan/core.c:1273: undefined reference to `__atomic_fetch_nand_8' powerpc64-linux-ld: kernel/kcsan/core.o: in function `__tsan_atomic64_compare_exchange_strong': kernel/kcsan/core.c:1273: undefined reference to `__atomic_compare_exchange_8' powerpc64-linux-ld: kernel/kcsan/core.o: in function `__tsan_atomic64_compare_exchange_weak': kernel/kcsan/core.c:1273: undefined reference to `__atomic_compare_exchange_8' powerpc64-linux-ld: kernel/kcsan/core.o: in function `__tsan_atomic64_compare_exchange_val': kernel/kcsan/core.c:1273: undefined reference to `__atomic_compare_exchange_8' 32 bits architectures don't have 64 bits atomic builtins. Only include DEFINE_TSAN_ATOMIC_OPS(64) on 64 bits architectures.
