Previously it was thought that all future Loongson cores would come with native CPUCFG. From new information shared by Huacai this is definitely not true (maybe some future 2K cores, for example), so collisions at PRID_REV level are inevitable. The CPU model matching needs to take PRID_IMP into consideration. The emulation logic needs to be disabled for those future cores as well, as we cannot possibly encode their non-discoverable features right now.

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.
