How much does one have to regress before it is a problem? I have two
projects I've worked on that "broke" due to this issue.

They were minor breakages though.

The "linux_logo" userspace sysinfo tool broke to the extent that it
was parsing for the bogomips string in /proc/cpuinfo and printed poorly
formatted and/or corrupted text info to screen when it couldn't find it.

The "PAPI" library had some really ancient (and poorly
thought-out) fallback code that would try to estimate MHz from bogomips
if a MHz value was not available via the traditional methods. This
failed after the change too, but not many people use PAPI on ARM so it
wasn't that big an issue.

I noticed these problems early, even before the change hit mainline.
But when I complained I was told in no uncertain terms that the ARM
maintainers were tired of hearing about bogomips issues and nothing
could be done to stop the change from getting in.
