Hi Viresh, Rafael,
Without this patch, schedutil is totally broken for us - is
there any chance at all this could go in 4.14 or is it just
too late?
Best Regards,
Chris

We stopped always reading utilization for the cpu we are running
the governor on, and instead read it for the cpu which we've been
told has updated utilization. This is stored in sugov_cpu->cpu.
The value is set in sugov_register but we clear it in sugov_start
which leads to always looking at the utilization of CPU0 instead
of the correct one.
Let's fix this by consolidating the initialization code into
sugov_start().
