In preparation for 32-bit MIPS huge page support. EVA,XPA are extended-addressing modes for 32-bit MIPS systems. Because huge pages aren't currently supported in 32-bit MIPS, this doesn't take any features away from EVA,XPA-enabled systems. However, the soon-to- come 32-bit MIPS huge page support doesn't yet support them. This also disables CPU_SUPPORTS_HUGEPAGES for the small number of 32-bit MIPS CPUs from Alchemy/Netlogic that support a custom 36-bit extended addressing. It's unknown if they even support huge pages in hardware.

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.
