From f318c8be797f8572629d5386a88cde7d753457a8 Mon Sep 17 00:00:00 2001 From: "Ritesh Harjani (IBM)" Date: Wed, 17 Apr 2024 20:37:40 +0530 Subject: powerpc/ptdump: Fix walk_vmemmap() to also print first vmemmap entry Currently walk_vmemmap() skips the first vmemmap entry pointed to by vmemmap_list pointer itself. Fix that. With the fix applied the vmemmap entry at 0xc00c000000000000 for hash is displayed: $ cat /sys/kernel/debug/kernel_hash_pagetable ... 0xc00c000000010000: AVPN:cd7bd4e0000 ssize: 1T ... 0xc00c000000000000: AVPN:cd7bd4e0000 ssize: 1T ...
