commit 2868e0703d5b8c8e60c6f60de13e876c4d85daa0
Author: Andreas Schwab <schwab@suse.de>
Date:   Mon Aug 11 11:18:26 2014 +0200

    Filter out PTHREAD_MUTEX_NO_ELISION_NP bit in pthread_mutexattr_gettype (BZ #15790)
    
    pthread_mutexattr_settype adds PTHREAD_MUTEX_NO_ELISION_NP to kind,
    which is an internal flag that pthread_mutexattr_gettype shouldn't
    expose, since pthread_mutexattr_settype wouldn't accept it.
