There is no point in turning individual options off and then on again, or vice versa, as the last one always wins. Now that -Wextra always gets passed first, remove all the redundant lines about warnings that are implied by either -Wall or -Wextra, and keep only the last one that disables it in some configurations. This should not have any effect but keep the Makefile more readable and the command line shorter.

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 reStructuredText 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.
