When using gcc (SUSE Linux) 7.5.0 (on openSUSE 15.3), I see a build
warning:
kernel/trace/trace_osnoise.c: In function 'start_kthread':
kernel/trace/trace_osnoise.c:1461:8: warning: 'main' is usually a function [-Wmain]
void *main = osnoise_main;
^~~~
Quieten that warning by using "-Wno-main". It's OK to use "main" as a
declaration name in the kernel.
Build-tested on most ARCHes.
[ v2: only do it for gcc, since clang doesn't have that particular warning ]

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.
