From b06a6717873560e9dd1c07357781fc2b27545701 Mon Sep 17 00:00:00 2001 From: Nathan Lynch Date: Mon, 7 Dec 2020 15:51:39 -0600 Subject: [PATCH] powerpc/pseries/mobility: don't error on absence of ibm, update-nodes Treat the absence of the ibm,update-nodes function as benign instead of reporting an error. If the platform does not provide that facility, it's not a problem for Linux.
