+ [BZ #17319]
+ * sysdeps/i386/nptl/tls.h (TLS_INIT_TP): Use INTERNAL_SYSCALL
+ to call set_thread_area instead of hand written asm.
+ (__NR_set_thread_area): Removed define.
+ (TLS_FLAG_WRITABLE): Likewise.
+ (__ASSUME_SET_THREAD_AREA): Remove check.
+ (TLS_EBX_ARG): Remove define.
+ (TLS_LOAD_EBX): Likewise.
