From: Lucas Oakley <soakley(a)redhat.com&gt; This simplication fixes the total CPU count being reported incorrectly in ppc64le and s390x systems when some number of CPUs have been offlined, as the kt->cpus value is adjusted. This adds the word "OFFLINE" to the 'sys' output for s390x and ppc64le, like exists for x86_64 and aarch64 when examining systems with offlined CPUs.
