Update.

2003-08-15  Ulrich Drepper  <drepper@redhat.com>

	* io/Versions [GLIBC_2.3.3]: Add posix_fadvise64.
	* io/fcntl.h (posix_fadvise64): Change type of third parameter to
	off_t.
	* sysdeps/unix/sysv/linux/posix_fadvise.c: Adjust definition.
	* sysdeps/unix/make-syscalls.sh: Recognize V prefix to the parameter
	description indicating the error value is returned, not -1.
	* sysdeps/unix/sysv/linux/Makefile [subdir=io] (subdir_routines): Add
	posix_fadvise64_64.
	* sysdeps/unix/sysv/linux/kernel-features.h: Add definition of
	__ASSUME_FADVISE64_64_SYSCALL.
	* sysdeps/unix/sysv/linux/syscalls.list: Don't define madvise and
	posix_madvise in one file.  Have posix_madvise defined with error
	value returned.
	Define posix_fadvise64_64 entry.  Add version info to posix_fadvise64
	entry.
	* sysdeps/unix/sysv/linux/alpha/syscalls.list: Define
	posix_fadvise64_64 entry.  Add version info to posix_fadvise64 entry.
	* sysdeps/unix/sysv/linux/ia64/syscalls.list: Likewise.
	* sysdeps/unix/sysv/linux/x86_64/syscalls.list: Likewise.
	* sysdeps/unix/sysv/linux/i386/posix_fadvise.S: New file.
	* sysdeps/unix/sysv/linux/i386/sysdep.h: Define PSEUDO_ERRVAL,
	PSEUDO_END_ERRVAL, and ret_ERRVAL.
	* sysdeps/unix/sysv/linux/ia64/sysdep.h: Likewise.
	* sysdeps/unix/sysv/linux/x86_64/sysdep.h: Likewise.

	* posix/Makefile (routines): Add posix_madvise.
	* sysdeps/generic/madvise.c: Don't define posix_madvise.
	* sysdeps/generic/posix_madvise.c: New file.
	* sysdeps/unix/sysv/aix/posix_madvise.c: New file.
