From e2e4f64118d128c41bd3c787afd2b9822ab758cd Mon Sep 17 00:00:00 2001 From: David Gibson Date: Wed, 28 Mar 2018 14:45:44 +1100 Subject: spapr: Add cpu_apply hook to capabilities MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit spapr capabilities have an apply hook to actually activate (or deactivate) the feature in the system at reset time. However, a number of capabilities affect the setup of cpus, and need to be applied to each of them - including hotplugged cpus for extra complication. To make this simpler, add an optional cpu_apply hook that is called from spapr_cpu_reset().
