+Subject: sparc: huge_ptep_set_* functions need to call set_huge_pte_at()
+
+
+From: Dave Kleikamp <dave.kleikamp@oracle.com>
+
+[ Upstream commit 6cb9c3697585c47977c42c5cc1b9fc49247ac530 ]
+
+Modifying the huge pte's requires that all the underlying pte's be
+modified.
+
+Version 2: added missing flush_tlb_page()
