Subject: [PATCH mmotm] sparc64: pgtable_64.h: fix mismatched parens

From: Randy Dunlap <rdunlap@...radead.org>

Fix lib-untag-user-pointers-in-strn_user.patch unmatched left paren.
Fixes many of these build errors:

../mm/gup.c: In function '__get_user_pages':
../mm/gup.c:791:30: error: expected ')' before ';' token
  start = untagged_addr(start);
                              ^
In file included from ../arch/sparc/include/asm/pgtable.h:5,
                 from ../include/linux/mm.h:99,
                 from ../mm/gup.c:7:
../arch/sparc/include/asm/pgtable_64.h:1102:2: note: to match this '('
  ((__typeof__(addr))(__untagged_addr((unsigned long)(addr)))
  ^
../mm/gup.c:791:10: note: in expansion of macro 'untagged_addr'
  start = untagged_addr(start);
          ^~~~~~~~~~~~~
../mm/gup.c:892:21: error: expected ';' before '}' token
