    Subject[PATCH v2] kernel/cpu.c: Add right qualifiers for alloc_frozen_cpus() and cpu_hotplug_pm_sync_init()
    Date
    From: Fenghua Yu <fenghua.yu@intel.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.
