Very long subject and missed description.

Let me suggest to replace the subject as "pps kapi: use 
ktime_get_boottime_ts64() to include time spent in sleep".

And add a description as:

Since ktime_get() stops during suspend, we replace it with 
ktime_get_boottime_ts64() because elapsed realtime includes time spent in sleep 
and pps should be also including sleep time.

Ciao,

Rodolfo
