Actually I'm going to see runstate update impact on the context switch time. 
For that I will extend TBM with runstate setup.
I really do not like a bunch of `copy_to_guest()` done on each context switch 
because of runstate.
If you are against runstate mapping, I'd like to fit runstate into a page, than 
access it directly from the hypervisor.
