Update.
2003-04-12  Ulrich Drepper  <drepper@redhat.com>

	* sysdeps/generic/dl-tls.c (_dl_allocate_tls_init): Add cast to
	avoid warning.

	* sysdeps/unix/sysv/linux/i386/sigaction.c (__libc_sigaction): If
	__ASSUME_VSYSCALL is defined don't add restorer.
	* sysdeps/unix/sysv/linux/kernel-features.h: Define
	__ASSUME_VSYSCALL for 2.5.53.
