Kernel patch complains about arm-related files.
I guess we need x86/x86_64 equivalent changes?

Estimated error went down.
Kernel pll stayed at zero.
ntpq shows offsets that are lower. Jitter also lower.
But how do I get the error more constant?
Currently the `ntpq -c kerninfo` estimated error is quite noisy.
I guess the noise is related to the variance in the interrupt latency?
How will the proposed communication between GPS receiver and computer be
able to cope with this variance?
