From 254eb5505ca0ca749d3a491fc6668b6c16647a99 Mon Sep 17 00:00:00 2001 From: "Kirill A. Shutemov" Date: Fri, 30 Nov 2018 23:23:28 +0300 Subject: x86/dump_pagetables: Fix LDT remap address marker The LDT remap placement has been changed. It's now placed before the direct mapping in the kernel virtual address space for both paging modes. Change address markers order accordingly.
