Subject[PATCH] mm: mark gup_pud_range as unused
Date
The last caller to gup_pud_range was removed in commit c2febafc6773
("mm: convert generic code to 5-level paging"). Mark it as unused to
silence a warning from gcc.

I saw this warning when compiling 4.11-rc2 with -Werror. An equally valid fix
would be to remove the function entirely but I went for the less invasive
approach.
