* sysdeps/s390/pthread_spin_lock.c (pthread_spin_lock): Use type
int for variable OLDVAL and correct inline assembler contraint. * sysdeps/s390/pthread_spin_trylock.c (pthread_spin_trylock): Use type int for variable OLD. * sysdeps/s390/tls.h (TLS_MULTIPLE_THREADS_IN_TCB): Define it only for s390-32. * sysdeps/unix/sysv/linux/s390/s390-64/sysdep-cancel.h (SINGLE_THREAD_P): Use global variable __local_multiple_threads instead of multiple_threads field in the TCB.
