Update.

2003-07-20  Ulrich Drepper  <drepper@redhat.com>

	* Makefile (libpthread-routines): Add pthread_attr_getaffinity and
	pthread_attr_setaffinity.
	* Versions [libpthread] (GLIBC_2.3.3): Likewise.
	* sysdeps/unix/sysv/linux/pthread_attr_getaffinity.c: New file.
	* sysdeps/unix/sysv/linux/pthread_attr_setaffinity.c: New file.
	* pthread_attr_destroy.c: Free cpuset element if allocated.
	* pthread_create.c: Pass iattr as additional parameter to
	create_thread.
	* sysdeps/pthread/createthread.c: If attribute is provided and
	a new thread is created with affinity set or scheduling parameters,
	start thread with CLONE_STOPPED.
	* sysdeps/pthread/pthread.h: Declare pthread_attr_getaffinity and
	pthread_attr_setaffinity.
	* sysdeps/unix/sysv/linux/internaltypes.h (struct pthread_attr): Add
	cpuset element.
