2023-03-30docs: move x86 documentation into Documentation/arch/Jonathan Corbet1-240/+0
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.
