#     powerpc/mm: Fix section mismatch warning in stop_machine_change_mapping()
#     
#     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.
