From 6663864e950d40c467ae4ab81c4dac64d7a8d9e6 Mon Sep 17 00:00:00 2001 From: Bharata B Rao Date: Mon, 3 Aug 2015 11:05:40 +0530 Subject: [PATCH] spapr: Populate ibm,associativity-lookup-arrays correctly for non-NUMA When NUMA isn't configured explicitly, assume node 0 is present for the purpose of creating ibm,associativity-lookup-arrays property under ibm,dynamic-reconfiguration-memory DT node. This ensures that the associativity index property is correctly updated in ibm,dynamic-memory for the LMB that is hotplugged.
