• 14a3b6abe   timekeeping: Store cycle_last value in timekeeper struct as well ... Browse Code »

  For implementing a shadow timekeeper and a split calculation/update
  region we need to store the cycle_last value in the timekeeper and
  update the value in the clocksource struct only in the update region.

  Add the extra storage to the timekeeper.
