Comment 12 for bug 1764628

Ok. so in xenial, on top of upstream release we cherrypick a few lscpu "fixes" for various arches, including powerpc from, what at the time was development. Clearly we didn't cherrypick enough of things, hence the lscpu regression. By 2.31 as used in bionic, things are all fine again.

So there must be patches in upstream util-linux between 2.27 and 2.31 which we do not have, but need to fix this.
