In order to demonstrate how new time-sources are added to my
timer-changes patch. Here is my current version of my cyclone-timer
patch for 2.5.41. This uses the infrastructure set up in the
timer-changes_A4 patch set to add the cyclone counter (found on IBM
Summit Based hardware) as a time-source.

        The current code is not enabled as it also depends on James
Cleverdon's 2.5 summit patch, however it illustrates how cleanly new
time-sources can be added.
