--- Comment #1001 from D. Hugh Redelmeier (hugh at mimosa.com) ---
The patch says it only applies to "Valleyview" systems.  As far as I can tell,
that includes all Bay Trail chips, and nothing else.  Comments about other
systems should be disregarded.

The patch is self-described as a work-around.  This is a tacit admission of a
chip bug.  With no fix for over 4 years.  At least they didn't give up.
