There is no need to set 0 to variables such as config-targets, mixed-targets, etc. Unset instead of setting 0 in order to use 'ifdef' to test them. I also renamed: config-targets -> config-build mixed-targets -> mixed-build dot-config -> need-config to clarify what we are doing. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
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.
