Steven Price af6513ead0 riscv: mm: add p?d_leaf() definitions ... 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 is provided by the p?d_leaf() functions/macros. For riscv a page is a leaf page when it has a read, write or execute bit set on it.
