Update.
2004-12-04 Ulrich Drepper <drepper@redhat.com> * sysdeps/unix/sysv/linux/i386/clone.S: Add support for NPTL where the PID is stored at userlevel and needs to be reset when CLONE_THREAD is not used. * sysdeps/unix/sysv/linux/86_64/clone.S: Likewise. * sysdeps/unix/sysv/linux/arm/clone.S: Update uses of RETINSTR. * sysdeps/unix/sysv/linux/arm/mmap.S: Likewise. * sysdeps/unix/sysv/linux/arm/mmap64.S: Likewise. * sysdeps/unix/sysv/linux/arm/socket.S: Likewise. * sysdeps/unix/sysv/linux/arm/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/arm/vfork.S: Likewise.
