From 72a7af33e08083c118b57c93c1456cc9a5045dc6 Mon Sep 17 00:00:00 2001 From: Mike Rapoport Date: Sat, 27 Jun 2020 11:16:52 +0300 Subject: sparc32: use PUD rather than PGD to get PMD in srmmu_inherit_prom_mappings() This is a misprint in the page table traversal in srmmu_inherit_prom_mappings`() function which accessed a PMD entry using PGD rather than PUD. Since sparc32 has only 3 page table levels, the PGD and PUD are essentially the same and usage of __nocache_fix() removed the type checking. Use PUD for the consistency and to avoid breakage because of upcoming addition of type checking into __nocache_fix().
