	* nis/nis_domain_of_r.c (nis_domain_of_r): Use libnsl_hidden_def,
	not libnsl_hidden_proto.

	* sysdeps/unix/sysv/linux/s390/s390-32/clone.S (__clone): Add support
	for NPTL where the PID is stored at userlevel and needs to be reset
	when CLONE_THREAD is not used.
	* sysdeps/unix/sysv/linux/s390/s390-64/clone.S (__clone): Likewise.

	* sysdeps/unix/sysv/linux/powerpc/powerpc64/clone.S (__clone): Save
	and restore r2 around call to fn.
