#     powerpc/mem: Add back missing header to fix 'no previous prototype' error
#     
#     Commit b26e8f27253a ("powerpc/mem: Move cache flushing functions into
#     mm/cacheflush.c") removed asm/sparsemem.h which is required when
#     CONFIG_MEMORY_HOTPLUG is selected to get the declaration of
#     create_section_mapping().
#     
#     Add it back.
#
