    Subject[PATCH v3 07/34] hexagon: mm: Add p?d_large() definitions
    Date
    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_large() functions/macros.

    For hexagon, we don't support large pages, so add a stub returning 0.
