From 8b16cd238d414b8942a23f0f753cdc57b17c231a Mon Sep 17 00:00:00 2001 From: Milton Miller Date: Thu, 8 Jan 2009 02:19:45 +0000 Subject: [PATCH] powerpc/numa: Remove redundant find_cpu_node() Use of_get_cpu_node, which is a superset of numa.c's find_cpu_node in a less restrictive section (text vs cpuinit).
