Update.
2003-01-13 Martin Schwidefsky <schwidefsky@de.ibm.com>
* sysdeps/unix/sysv/linux/s390/s390-32/pt-initfini.c: Avoid
unterminated string literals.
* sysdeps/unix/sysv/linux/s390/s390-64/pt-initfini.c: Likewise.
2003-01-13 Martin Schwidefsky <schwidefsky@de.ibm.com>
* sysdeps/unix/sysv/linux/s390/s390-32/sysdep-cancel.h
(PSEUDO): Code reordering. Move CENABLE and CDISABLE literals from
PSEUDO_END to PSEUDO.
(PSEUDO_END): Remove.
(SINGLE_THREAD_P): Save an instruction.
* sysdeps/unix/sysv/linux/s390/s390-32/vfork.S (__vfork): Add missing
parameter to SINGLE_THREAD_P call.
* sysdeps/unix/sysv/linux/s390/s390-64/sysdep-cancel.h (PSEUDO):
Code reordering.
