* pthread_rwlock_rdlock.c (__pthread_rwlock_rdlock): Add LLL_SHARED
parameter to lll_futex_wait call. * pthread_rwlock_wrlock.c (__pthread_rwlock_wrlock): Likewise. * sysdeps/unix/sysv/linux/powerpc/pthread_once.c (__pthread_once): Replace lll_futex_wait with lll_private_futex_wait. * sysdeps/unix/sysv/linux/powerpc/sem_post.c (__new_sem_post): Add LLL_SHARED parameter to lll_futex_wake(). * sysdeps/unix/sysv/linux/powerpc/lowlevellock.h: Define LLL_PRIVATE LLL_SHARED, lll_private_futex_wait, lll_private_futex_timed_wait and lll_private_futex_wake. (lll_futex_wait): Add private parameter. Adjust FUTEX_PRIVATE_FLAG bit from private parm before syscall. (lll_futex_timed_wait): Likewise. (lll_futex_wake): Likewise. (lll_futex_wake_unlock): Likewise. (lll_mutex_unlock): Add LLL_SHARED parm to lll_futex_wake call. (lll_robust_mutex_unlock): Likewise. (lll_mutex_unlock_force): Likewise.
