    powerpc/mm: Fix section mismatch warning in stop_machine_change_mapping() · bde709a7
    Mauricio Faria de Oliveira authored
    Fix the warning messages for stop_machine_change_mapping(), and a number
    of other affected functions in its call chain.
    
    All modified functions are under CONFIG_MEMORY_HOTPLUG, so __meminit
    is okay (keeps them / does not discard them).
    
    Boot-tested on powernv/power9/radix-mmu and pseries/power8/hash-mmu.
    
        $ make -j$(nproc) CONFIG_DEBUG_SECTION_MISMATCH=y vmlinux
        ...
          MODPOST vmlinux.o
        WARNING: vmlinux.o(.text+0x6b130): Section mismatch in reference from the function stop_machine_change_mapping() to the function .meminit.text:create_physical_mapping()
        The function stop_machine_change_mapping() references
        the function __meminit create_physical_mapping().
        This is often because stop_machine_change_mapping lacks a __meminit
        annotation or the annotation of create_physical_mapping is wrong.
