Even if the value isn't reset during suspend/resume we want the 
clocksource to keep counting. Or is it ok to have the clocksource stop 
or freeze during suspend?
Then we have cpuidle. Is it ok to stop/freeze the timer during cpuidle 
sleep states?
My view is that sched_clock and the clocksource read should return the 
time since boot and keep counting during sleep and suspend. (In this 
case we use the same timer for both sched_clk and clocksource.)

I agree that fixing it for everyone would be better and I can give it a 
try if I get pointed in the right direction.
