* 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.
