Make sched_clock() report time since boot rather than time since last timer interrupt. Make sched_clock() expand and scale the 32-bit TSC value running at IOCLK speed (~33MHz) to a 64-bit nanosecond counter, using cnt32_to_63() acquired from the ARM arch and without using slow DIVU instructions every call.
