Currently, the /proc/cpuinfo outputs the entire riscv,isa string which is not ideal when we have multiple ISA extensions present in the ISA string. Some of them may not be enabled in kernel as well. Same goes for the single letter extensions as well which prints the entire ISA string. Some of they may not be valid ISA extensions as well (e.g 'su') Parse only the valid & enabled ISA extension and print them.

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.
