I'd call that a bug, too.

This one is identical to the generic sys_stime function (despite the
comment above it), so it should be merged as well.

I'd prefer having an extra __ARCH_WANT_COMPAT_SYS_TIME flag. Mips, x86_64,
ia64 and s390 only need compat_sys_stime, but not sys_stime for 64 bit
kernels.
Also, the comment you copied from sys_stime is apparently superceded by
introduction of __ARCH_WANT_XYZ.
