From bb7c3d36e3b18aa02d34358ae75e1b91f69a968b Mon Sep 17 00:00:00 2001 From: Nathan Lynch Date: Fri, 12 Jun 2020 00:12:35 -0500 Subject: [PATCH] powerpc/pseries: remove prrn special case from DT update path pseries_devicetree_update() is no longer called with PRRN_SCOPE. The purpose of prrn_update_node() was to remove and then add back a LMB whose NUMA assignment had changed. This has never been reliable, and this codepath has been default-disabled for several releases. Remove prrn_update_node().
