spapr: Fix ibm, associativity for memory nodes We want the associtivity lists of memory and CPU nodes to match but memory nodes have incorrect domain#3 which is zero for CPU so they won't match. This clears domain#3 in the list to match CPUs associtivity lists. Signed-off-by: Alexey Kardashevskiy <aik@ozlabs.ru> Signed-off-by: Alexander Graf <agraf@suse.de>
