    Cleanup non-arch xtime uses, use get_seconds() or current_kernel_time(). · 2c6b47de

    This avoids use of the kernel-internal "xtime" variable directly outside
    of the actual time-related functions.  Instead, use the helper functions
    that we already have available to us.
    
    This doesn't actually change any behaviour, but this will allow us to
    fix the fact that "xtime" isn't updated very often with CONFIG_NO_HZ
    (because much of the realtime information is maintained as separate
    offsets to 'xtime'), which has caused interfaces that use xtime directly
    to get a time that is out of sync with the real-time clock by up to a
    third of a second or so.
