walk_page_range() is going to be allowed to walk page tables other than those of user space. For this it needs to know when it has reached a 'leaf' entry in the page tables. This information will be provided by the p?d_leaf() functions/macros. For arc, we only have two levels, so only pmd_leaf() is needed.
