    This change adds a warning when CONFIG_SMP is not set:

    arch/i386/power/cpu.c: In function '__restore_processor_state':
    arch/i386/power/cpu.c:137: warning: implicit declaration of function
    'enable_sep_cpu'
    Maybe those functions should be defined somewhere else.

    regards,

    Benoit
