Your interpretation of that patch is wrong.  The patch you refer to is
consolidating what's already there.

Just make sure you use the sched_clock infrastructure already provided
on ARM and provided you give it the correct information - and set it up
early enough (in init_early) you will not have any sched_clock() wraps.
This is because a timer will be set to automatically update things
before any wrap occurs.
