[PATCH 2/2] x86/dump_pagetables: Fix LDT remap address marker

From: Kirill A. Shutemov
Date: Fri Nov 30 2018 - 06:58:13 EST


The LDT remap placement has been changed. It's now placed before direct
mapping in the kernel virtual address space for both paging modes.

Change address markers order accordingly.
