* We use the full linear equation: f(x) = a + b*x, in order to allow
* a continuous function in the face of dynamic freq changes.
*
* Continuity means that when our frequency changes our slope (b); we want to
* ensure that: f(t) == f'(t), which gives: a + b*t == a' + b'*t.
*
* Without an offset (a) the above would not be possible.
*
* See the comment near cycles_2_ns() for details on how we compute (b).
