Just need to make sure that the function is not calling directly or indirectly
another __meminit function, then it is safe to remove it.
E.g:
sparse_add_one_section() is wrapped around CONFIG_MEMORY_HOTPLUG, but the
__meminit must stay because it calls sparse_index_init(),
sparse_init_one_section() and sparse_mem_map_populate(), all three marked as
__meminit because they are also used out of hotplug scope, during early boot.
