It's not these sort of tools I was worried about. I was thinking about the possibility of badly written parsers which want some other field from cpuinfo, but use the bogomips line for context. Do these applications exist? No idea. My second (less stupid) version of the patch prints "not reported". I'd be happy to remove the line altogether if people get behind the decision though. In fact, I just tried it and at least my linaro filesystem seems happy enough.
