From 88f42c6773c0c09f5c38d5eb0cd6e8b7aed4dfeb Mon Sep 17 00:00:00 2001 From: David Gibson Date: Thu, 5 Apr 2018 15:49:23 +1000 Subject: [PATCH] spapr: Set compatibility mode before the rest of spapr_cpu_reset() Although the order doesn't really matter at the moment, it's possible other initializastions could depend on the compatiblity mode, so make sure we set it first in spapr_cpu_reset(). While we're at it drop the test against first_cpu. Setting the compat mode to the value it already has is redundant, but harmless, so we might as well make a small simplification to the code.
