* sysdeps/mach/hurd/munlock.c: New file.
* sysdeps/mach/hurd/bits/posix_opt.h (_POSIX_MEMLOCK_RANGE): Define it.
* misc/Makefile (routines): Add mlock munlock mlockall munlockall.
* sysdeps/generic/mlock.c: New file.
* sysdeps/generic/munlock.c: New file.
* sysdeps/generic/mlockall.c: New file.
* sysdeps/generic/munlockall.c: New file.
* sysdeps/generic/bits/mman.h (MCL_CURRENT, MCL_FUTURE): New macros.
* sysdeps/unix/sysv/linux/syscalls.list (mlock, munlock,
mlockall, munlockall): Change caller field to - from EXTRA.
Don't use __ names; not used (and not declared in include/sys/mman.h).
Reverse the change of 1998-04-22. Providing a struct dirent with
different members when __USE_FILE_OFFSET64 is defined is asking
for trouble. Instead add the necessary LFS magic to the 4.4BSD
header.
* sysdeps/unix/bsd/bsd4.4/bits/dirent.h: Add LFS definitions.
* sysdeps/mach/hurd/bits/dirent.h: Removed.
* sysdeps/mach/hurd/readdir64.c: Removed.
* sysdeps/mach/hurd/readdir64_r.c: Removed.
* sysdeps/generic/bits/mman.h [__USE_MISC] (MAP_ANONYMOUS): Define as
alias for MAP_ANON.
* stdio/stdio.h (sys_errlist, sys_nerr, _sys_errlist, _sys_nerr):
Remove decls. They don't exist at all on the Hurd.
