* sysdeps/pthread/createthread.c (ARCH_CLONE): Define if not defined. (create_thread): Only assert PD->tcb != NULL under [TLS_TCB_AT_TP]. Use ARCH_CLONE. * allocatestack.c (ALLOCATE_STACK_PARMS): New macro. [NEED_SEPARATE_REGISTER_STACK] (STACK_VARIABLES, STACK_VARIABLES_ARGS, STACK_VARIABLES_PARMS, ALLOCATE_STACK_PARMS, ALLOCATE_STACK): New macros. (TLS_TPADJ): New macro. (get_cached_stack, queue_stack, __deallocate_stack): Use TLS_TPADJ. (allocate_stack): Handle TLS_DTV_AT_TP and NEED_SEPARATE_REGISTER_STACK. Use TLS_TPADJ. * pthread_create.c (__pthread_create_2_1) [! TLS_TCB_AT_TP]: Don't set PD->self. * init.c [__ia64__] (__NR_set_tid_address): Define.
