From 5b958a7eef9e116c7be516924f27e5c62a9c6914 Mon Sep 17 00:00:00 2001 From: Gavin Shan Date: Wed, 30 May 2012 17:07:29 +0000 Subject: [PATCH] powerpc/numa: Fix OF node refcounting bug The form affinity for NUMA is set to 1 if the firmware supports OPAL. Otherwise, we have to retrieve that from OF node "/chosen". For the latter case, OF node "/chosen" reference count was never decreased.
