I couldn't find it either, but it is all over the linux code.

I'd be happy to remove it from this comment though.

Like I said; I went with whatever is on this here page:

  https://en.wikipedia.org/wiki/List_of_Intel_Atom_microprocessors

There is no Cedar Trail, or Bayview. If you could do me a delta patch
with the names you think are appropriate i'd be happy to fold it in.
Alternatively, I can remove the tail comments entirely.

I spend entirely too much time already trying to come up with sensible
names already.
