we always define the padding space. [!TLS_DTV_AT_TP]: Give tcbhead_t field a name, `header', since GCC stopped supporting its own extensions fully. [TLS_MULTIPLE_THREADS_IN_TCB]: Put `multiple_threads' inside a wrapper struct also called `header', so `header.multiple_threads' is the field name to use on all machines. * allocatestack.c (allocate_stack): Use `header.' prefix. * sysdeps/pthread/createthread.c (create_thread): Likewise. * pthread_create.c (__pthread_create_2_1): Likewise. * sysdeps/i386/tls.h (INSTALL_NEW_DTV, THREAD_DTV): Likewise. (THREAD_SELF): Likewise. * sysdeps/x86_64/tls.h: Likewise. * sysdeps/unix/sysv/linux/i386/sysdep-cancel.h (SINGLE_THREAD_P): Likewise. * sysdeps/unix/sysv/linux/sh/sysdep-cancel.h (SINGLE_THREAD_P): Likewise. * sysdeps/unix/sysv/linux/s390/s390-64/sysdep-cancel.h (SINGLE_THREAD_P): Likewise. * sysdeps/s390/td_ta_map_lwp2thr.c (td_ta_map_lwp2thr): Use REGS[18] value directly.
