Subject: [PATCH AUTOSEL 4.14 19/59] x86/dump_pagetables: Fix LDT remap address marker
Date: Wed, 26 Dec 2018 17:37:59 -0500 [thread overview]
Message-ID: <20181226223839.150262-19-sashal@kernel.org> (raw)
In-Reply-To: <20181226223839.150262-1-sashal@kernel.org>
From: "Kirill A. Shutemov" <kirill.shutemov@linux.intel.com>
[ Upstream commit 254eb5505ca0ca749d3a491fc6668b6c16647a99 ]
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.
Fixes: d52888aa2753 ("x86/mm: Move LDT remap out of KASLR region on 5-level paging")
