No, it didn't get me confused - it got you confused that I'm confused.

You need to read the comment as a *whole*. The zero value is special
because it is *used* to *denote* a failure. You can use any other
invalid revision value for that matter.

Maybe "denote" was not precise enough - maybe it should say "0 is an
invalid microcode revision and is used to detect the failure of a
microcode update" or similar. Yeah, "detect" sounds better.
