From 017c217a26e9bf6948482f751b30d0507e30a7d0 Mon Sep 17 00:00:00 2001 From: Tang Chen Date: Thu, 6 Feb 2014 12:04:25 -0800 Subject: arch/x86/mm/numa.c: initialize numa_kernel_nodes in numa_clear_kernel_node_hotplug() On-stack variable numa_kernel_nodes in numa_clear_kernel_node_hotplug() was not initialized. So we need to initialize it.
