For the RT patchset, add a preempt-rt fragment to the "mainline" fragment directory to make it easier to build automatically without having to go into menuconfig and select the Fully Preemptible Kernel (RT) to be the Preemption Model and to turn of CPU Frequency scaling. It isn't mandatory to turn off CPU_FREQ. However, you get a more predictable latency range.

Hi Andrey,
I'm unsure but can this fragment be added to the config-core-4.1 branch?
Cheers, Anders
