Hello.
Since 4.8 frequencies in /proc/cpuinfo aren't dynamically updated anymore. I guess they are stuck to the values written during boot as I get different values from boot to boot.
This wasn't the case with 4.7.x or any previous kernel series.
Please fix.

I proposed a patch to make /proc/cpuinfo accurate several months ago. Red Hat didn't like it, arguing that changing values is a support issue. So there was not agreement on what to do here -- let's go find out if it changed by mistake...
