This reverts commit 7cab91b87d.
Now when we have a real hardware platform with PAE40 enabled
(here I mean axs103 with firmware v1.2) and 1 Gb of DDR mapped to
0x1_a000_0000-0x1_ffff_ffff we're really targeting memory above 4Gb
when PAE40 is enabled. This in its turn requires HIGHMEM to be enabled
otherwise user won't see any difference with enabling PAE in
kernel configuration as only lowmem will be used anyways.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
