Please note, the use of the ktime_get_raw_ns() is *only* used as a fallback on 
architectures where random_get_entropy / get_cycles is not implemented.

So, on X86 and on many other arches, this function call will never be 
triggered.

Will do.

@Arnd: I would prepare a patch then using ktime_get_raw_ns and providing a 
good documentation in the code.
