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.
