The notifier gets already called with a pointer to the time keeper. That xen implementation just does not use it. We extract exactly that information in the vdso updates without calling back into the core code. So for solving that xen thing we do not need a 64 bit variant of __current_kernel_time() at all. The notifier has the pointer to the timekeeper and can just grab data from there. > There's one useage in kdb thats maybe problematic, so maybe this will > need a deeper cleanup. That one is silly as well. It only wants to know the seconds portion.
