Update.

2002-05-30  Ulrich Drepper  <drepper@redhat.com>

	* sysdeps/unix/sysv/linux/Makefile [$(subdir)==misc] (sysdep_routines):
	Add readahead.
	* sysdeps/unix/sysv/linux/readahead.c: New file.
	* sysdeps/unix/sysv/linux/syscalls.list: Add sendfile64 syscall.
	* sysdeps/unix/sysv/linux/Versions: Export readahead and sendfile64.
	* sysdeps/unix/sysv/linux/alpha/syscalls.list: Add readahead syscall.
	Add sendfile64 alias to sendfile syscall.
	* sysdeps/unix/sysv/linux/ia64/syscalls.list: Likewise.
	* sysdeps/unix/sysv/linux/sparc/sparc64/syscalls.list: Likewise.
	* sysdeps/unix/sysv/linux/x86_64/syscalls.list: Likewise.
	* sysdeps/unix/sysv/linux/powerpc/syscalls.list: Add s_readahead
	syscall.

	* sysdeps/unix/sysv/linux/i386/sysdep.h: Use __i686.get_pc_thunk.XX
	special section for PIC register loading.
	* sysdeps/unix/sysv/linux/i386/i686/sysdep.h: Likewise.

	* config.h.in: Define HAVE_HIDDEN.
	* configure.in: Also define HAVE_HIDDEN if HAVE_PROTECTED is defined.

	* elf/elf.h: Correct Alpha TLS relocations according to last spec.
