Update.
2002-07-24 Philip Blundell <philb@gnu.org>
* sysdeps/unix/sysv/linux/arm/ioperm.c (init_iosys): Yield ENODEV
on unknown systems.
2003-02-20 Franz Sirl <Franz.Sirl-kernel@lauterbach.com>
* sysdeps/powerpc/powerpc32/atomicity.h: Remove compiler workaround.
* sysdeps/unix/sysv/linux/kernel-features.h
(__ASSUME_NEW_PRCTL_SYSCALL): Defined for ppc32 too.
* sysdeps/unix/sysv/linux/powerpc/powerpc32/fe_nomask.c: Use prctl
if possible.
* sysdeps/unix/sysv/linux/powerpc/powerpc32/vfork.S: Avoid short
interprocedure branches.
* sysdeps/powerpc/soft-fp/Dist (sim-full.c, fenv_const.c): Move to...
* sysdeps/powerpc/nofpu/Dist: ...here.
* sysdeps/unix/sysv/linux/powerpc/Dist (fe_nomask.c): Move to...
* sysdeps/unix/sysv/linux/powerpc/powerpc32/Dist: ...here.
* sysdeps/unix/sysv/linux/s390/s390-64/Dist (kernel_stat.h): Delete.
* sysdeps/unix/sysv/linux/sparc/Dist (bits/utmpx.h): Delete.
