Subject: [PATCH v2] kernel/cpu.c: Add right qualifiers for alloc_frozen_cpus() and cpu_hotplug_pm_sync_init() 

From: Fenghua Yu <fenghua.yu@...el.com>

Add __init for functions alloc_frozen_cpus() and cpu_hotplug_pm_sync_init()
because they are only called during boot time.

Add static for function cpu_hotplug_pm_sync_init() because its scope is limited
in this file only.

Signed-off-by: Fenghua Yu <fenghua.yu@...el.com>
