From ff61f0791ce969d2db6c9f3b71d74ceec0a2e958 Mon Sep 17 00:00:00 2001
From: Jonathan Corbet <corbet@lwn.net>
Date: Tue, 14 Mar 2023 17:06:44 -0600
Subject: [PATCH] docs: move x86 documentation into Documentation/arch/
Move the x86 documentation under Documentation/arch/ as a way of cleaning
up the top-level directory and making the structure of our docs more
closely match the structure of the source directories it describes.
All in-kernel references to the old paths have been updated.
