Subject: sparc: 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 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.
