    perf: Undo the per cpu-context timer stuff · e9d2b064
    Peter Zijlstra authored
    Revert the timer per cpu-context timers because of unfortunate
    nohz interaction. Fixing that would have been somewhat ugly, so
    go back to driving things from the regular tick. Provide a
    jiffies interval feature for people who want slower rotations.
