Subject: cpu hotplug fix
From: Chandra Seetharaman <sekharan@xxxxxxxxxx>
WARNING: drivers/cpufreq/cpufreq_stats.o - Section mismatch: reference to .init.data:cpufreq_stat_cpu_notifier from .exit.text after 'cleanup_module' (at offset 0x23)
WARNING: drivers/cpufreq/cpufreq_stats.o - Section mismatch: reference to .init.text: from .exit.text after 'cleanup_module' (at offset 0x28)
Make cpufreq_stat_cpu_callback() and cpufreq_stat_cpu_notifier available
irrespective of whether HOTPLUG_CPU is defined or not.
Also, use hotplug version of register/unregister cpu_notifiers.
