    Subject[PATCH SET - 0/3] lost tick fixes
    From
    Date
    Andrew, 
    This set of patches fixes up the time doubling issues seen on laptops
    with speedstep as well as other systems when HZ=100 or calibrate_tsc()
    wasn't precise enough. No last-minute hand-editing of the diffs were
    done and I've tested each step to insure they compile and boot. ;) The
    patches in the order they should be applied are:

    Patch 1: rename-timer_A1
    o Your cleanups to the time code.
    o Replaces your current rename-timer patch in your tree.
    o Removes dependency on lost-tick-speedset-fix.

    Patch 2: lost-tick-speedstep-fix_A1
    o Detects speedstep time trouble and falls back to the PIT
    o Replaces the lost-tick-speedstep-fix patch in your tree
    o Adds dependency on rename-timer-A1

    Patch 3: lost-tick-corner-fix_A0
    o Fixes corner case where we detect an overflow between time source
    reads.
    o Depends on lost-tick-speedstep-fix_A1

    Please consider for inclusion in your tree.

    thanks
    -john
