Many MIPS CPUs have optional CPU features which are not activated for
all CPU cores. Print the CPU options, which are implemented in the core,
in /proc/cpuinfo. This makes it possible to see which features are
supported and which are not supported. This should cover all standard
MIPS extensions. Before, it only printed information about the main MIPS
ASEs.

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.
