commitdb1503d355upstream. CONFIG_MAXPHYSMEM_* are actually never used, even the nommu defconfigs selecting the MAXPHYSMEM_2GB had no effects on PAGE_OFFSET since it was preempted by !MMU case right before. In addition, the move of the kernel mapping at the end of the address space broke the use of MAXPHYSMEM_2G with MMU since it defines PAGE_OFFSET at the same address as the kernel mapping.

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.
