+	* allocatestack.c (allocate_stack): Always initialize robust_head.
+	* descr.h: Define struct robust_list_head.
+	(struct pthread): Use robust_list_head in robust mutex list definition.
+	Adjust ENQUEUE_MUTEX and DEQUEUE_MUTEX.
+	* init.c [!__ASSUME_SET_ROBUST_LIST] (__set_robust_list_avail): Define.
+	(__pthread_initialize_minimal_internal): Register robust_list with
+	the kernel.
