From 7c7a532ba3fc51bf9527d191fb410786c1fdc73c Mon Sep 17 00:00:00 2001 From: Christophe Leroy Date: Wed, 14 Aug 2019 12:36:09 +0000 Subject: [PATCH] powerpc/ptdump: Fix addresses display on PPC32 Commit 453d87f6a8ae ("powerpc/mm: Warn if W+X pages found on boot") wrongly changed KERN_VIRT_START from 0 to PAGE_OFFSET, leading to a shift in the displayed addresses. Lets revert that change to resync walk_pagetables()'s addr val and pgd_t pointer for PPC32.
