[PATCH] powerpc/ptdump: fix addresses display on PPC32

From: Christophe Leroy
Date: Fri Aug 09 2019 - 10:58:15 EST


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.
