had to pull in linus' tree in order to get the latest 2.6.17 label,

    [PATCH] Time: Use clocksource infrastructure for update_wall_time

    Modify the update_wall_time function so it increments time using the
    clocksource abstraction instead of jiffies.  Since the only
clocksource driver
    currently provided is the jiffies clocksource, this should result in no
    functional change.  Additionally, a timekeeping_init and timekeeping_resume
    function has been added to initialize and maintain some of the new
timekeping
    state.
