Use 'choices' to check if the given parameter is valid.
I also simplified the help message because, with 'choices', --help
shows the list of valid parameters:
--log_level {DEBUG,INFO,WARNING,ERROR,CRITICAL}
I started the help message with a lower case, "the level of log ..."
in order to be consistent with the -h option:
-h, --help show this help message and exit
The message "show this help ..." comes from the ArgumentParser library
code, and I do not know how to change it. So, I changed our code.

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.
