Mmmm. Okay. Maybe I fixed the 'wrong' place, but the place I 'fixed'
was in do_slow_gettimeoffset, which is inside #ifndef CONFIG_X86_TSC.

I'll compile with a printk in there at home tonight though.

*peers more closely* Ho-ho. I see. There's one further down in the
timer interrupt itself. Oops. My bad.
