This reverts commit c1457d9aad5ee2feafcf85aa9a58ab50500159d2. The framework change to add D_GNU_SOURCE to KHDR_INCLUDES to Makefile, lib.mk, and kselftest_harness.h is reverted as it is causing build failures and warnings. Revert this change as this change depends on the framework change. Reported-by: Mark Brown <broonie@kernel.org> Signed-off-by: Shuah Khan <skhan@linuxfoundation.org>
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.
