Update.
* sysdeps/pthread/pthread_cond_wait.c (__pthread_cond_wait): Don't store mutex address if the current value is ~0l. * sysdeps/pthread/pthread_cond_timedwait.c (__pthread_cond_timedwait): Likewise. * sysdeps/pthread/pthread_cond_broadcast.c (__pthread_cond_broadcast): Don't use requeue for pshared condvars. * sysdeps/unix/sysv/linux/x86_64/pthread_cond_wait.S (__pthread_cond_wait): Don't store mutex address if the current value is ~0l. * sysdeps/unix/sysv/linux/x86_64/pthread_cond_timedwait.S (__pthread_cond_timedwait): Likewise. * sysdeps/unix/sysv/linux/x86_64/pthread_cond_broadcast.S (__pthread_cond_broadcast): Don't use requeue for pshared condvars. * pthread_cond_init.c (__pthread_cond_init): Initialize __mutex element with ~0l for pshared condvars, with NULL otherwise. * sysdeps/unix/sysv/linux/i386/i486/pthread_cond_wait.S (__pthread_cond_wait): Don't store mutex address if the current value is ~0l. * sysdeps/unix/sysv/linux/i386/i486/pthread_cond_timedwait.S (__pthread_cond_timedwait): Likewise. * sysdeps/unix/sysv/linux/i386/i486/pthread_cond_broadcast.S (__pthread_cond_broadcast): Don't use requeue for pshared condvars.
