From 74b85f3790aa2550c617fe14439482e13e615fa0 Mon Sep 17 00:00:00 2001 From: Chandra Seetharaman Date: Tue, 27 Jun 2006 02:54:09 -0700 Subject: [PATCH] cpu hotplug: make cpu_notifier related notifier blocks __cpuinit only Make notifier_blocks associated with cpu_notifier as __cpuinitdata. __cpuinitdata makes sure that the data is init time only unless CONFIG_HOTPLUG_CPU is defined.
