    x86: fix section mismatch warnings when referencing notifiers
    Fix the following warnings:
    WARNING: arch/x86/kernel/built-in.o(.exit.text+0xf8): Section mismatch in 
reference from the function msr_exit() to the variable
    WARNING: arch/x86/kernel/built-in.o(.exit.text+0x158): Section mismatch in 
reference from the function cpuid_exit() to the variable
    WARNING: arch/x86/kernel/built-in.o(.exit.text+0x171): Section mismatch in 
reference from the function microcode_exit() to the variable
    In all three cases there were a function annotated __exit
    that referenced a variable annotated __cpuinitdata.
    The fix was to replace the annotation of the notifier
    with __refdata to tell modpost that the reference to
    a _cpuinit function in the notifier are OK.
    The unregister call that references the notifier
    variable will simple delete the function pointer
    so there is no problem ignoring the reference.
    Note: This looks like another case where __cpuinit
    has been used as replacement for proper use
    of CONFIG_HOTPLUG_CPU to decide what code are used for
