Ard Biesheuvel 6ed8a3a094 arm64: mm: Add 5 level paging support to fixmap and swapper handling
Add support for using 5 levels of paging in the fixmap, as well as in
the kernel page table handling code which uses fixmaps internally.
This also handles the case where a 5 level build runs on hardware that
only supports 4 levels of paging.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
