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 sparc 64 bit, pmd_large() and pud_large() are already provided, so add macros to provide the p?d_leaf names required by the generic code. CC: "David S.
