commit 9d9358f2ebf5dd45c185b1f4d2937325ba721931

    hppa: Update pthread.h
    
    Updates the hppa-specific pthread.h from the generic version.
    After this update the only difference between the generic
    version and the hppa version is the footer protected by the
    _PTHREAD_H_HPPA_ guard.
