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