Some users of kmap() add an offset to the kmap() address to be used during the mapping. When converting to kmap_local_page() the base address does not need to be stored because any address within the page can be used in kunmap_local(). However, this was not clear from the documentation and cause some questions.[1] Document that any address in the page can be used in kunmap_local() to clarify this for future users.
