This system call seems to be duplicated in many architectures. Here's a patch which moves it to kernel/compat.c
We didn't touch ppc64, because it seems to be different. We've tested this on ia64 with LTP.

This patch moves sys32_adjtimex in 6 archs to kernel/compat.c.

I had done my own version of compat_sys_adjtimex and most of the other sys32_* functions that are worth consolidating some time ago. Unfortunately I never got around to bringing them into a proper patch for for submission. Would you like to have my code so you can finish it? As an alternative approach I can prepare patches that simply add the compat_sys_* functions and leave it to each arch maintainer to remove their own versions.

Great. The attachment contains compat my code for
{get,set}timeofday, open, sched_rr_get_interval, sendfile,
sysctl, sysinfo, time, ustat, utimes and all the uid16 syscalls.
These are merged carefully from all seven compat architectures,
but I never found the time to even compile testing them. Hopefully
you can make something out of this.
