Nothing serious, compile warnings ..
mm/sparse.c:244: warning: `__kmalloc_section_memmap' defined but not used mm/sparse.c:274: warning: `__kfree_section_memmap' defined but not used
Here is the patch.
Thanks, Badari
__kmalloc_section_memmap(), vaddr_in_vmalloc_area() and __kfree_section_memmap() are used only for MEMORY_HOTPLUG. Moved them under CONFIG_MEMORY_HOTPLUG.
