[lttng-dev] [PATCH] fix timestamps on architectures without CONFIG_KTIME_SCALAR

[Gerlando Falauto]

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.
