trace_clock_monotonic_wrapper() should return a u64 representing the number of nanoseconds since system startup. ktime_get() provides that value directly within its .tv64 field only on those architectures defining CONFIG_KTIME_SCALAR, whereas in all other cases (e.g. PowerPC) a ktime_to_ns() conversion (which translates back to .tv64 when CONFIG_KTIME_SCALAR is defined) becomes necessary.
