# grep -rn unregister_time_interpolator .
./kernel/timer.c:1893:unregister_time_interpolator(struct time_interpolator *ti)
./include/linux/timex.h:270:extern void unregister_time_interpolator(struct time_interpolator *);

I don't see a caller. i386 does not use time interpolator anyway.

# find -iname Kconfig | xargs grep TIME_INTERPOLATION
./arch/sparc64/Kconfig:37:config TIME_INTERPOLATION
./arch/ia64/Kconfig:60:config TIME_INTERPOLATION
