Arch Linux

Description: perf stat scales "secondary" units twice. This is an upstream bug that was introduced somewhat recently, and fixed by a patch from 2018 Dec 17
https://lore.kernel.org/patchwork/patch/1025968/ Commit-ID: 57ddf09173c1e7d0511ead8924675c7198e56545 that only changes 2 lines in the front-end.

Additional info:
* package version(s): perf 4.20-2, linux 4.20.3.arch1-1

Steps to reproduce:

perf stat awk 'BEGIN{for(i=0;i<10000000;i++){}}'

Performance counter stats for 'awk BEGIN{for(i=0;i<10000000;i++){}}':

My average CPU clock speed was 3.87 GHz, not 3876339.773 GHz. Obviously most of the other /sec units are wrong, too.
