Sounds good for me. I will take it through my tree.

By the way, I would like to do some cleanups in the Kconfig and 
consistently change the Kconfig options to be silent without the 
COMPILE_TEST option.

I am wondering if we can just remove the ARM_ARCH_TIMER_EVTSTREAM option 
with this patch applied and always enable it by default (like what is 
done today).
