ARM: 7830/1: delay: don't bother reporting bogomips in /proc/cpuinfo (9fc2105a) · Commits · 戴 / test

Now that we support a timer-backed delay loop, I'm quickly getting sick and tired of people complaining that their beloved bogomips value has decreased. You know who you are! This patch removes the bogomips line from /proc/cpuinfo, based on the reasoning that any program parsing this is already broken and, as such, won't be further broken if the field is removed.
