Richard reports that since772dd03427("mm: enumerate all gfp flags"), gfp-translate is broken, as the bit numbers are implicit, leaving the shell script unable to extract them. Even more, some bits are now at a variable location, making it double extra hard to parse using a simple shell script. Use a brute-force approach to the problem by generating a small C stub that will use the enum to dump the interesting bits. As an added bonus, we are now able to identify invalid bits for a given configuration. As an added drawback, we cannot parse include files that predate this change anymore. Tough luck.

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.
