The ifdeffery for atomic*_{fetch_,}andnot() is unlike that for all the
other atomics. If atomic*_andnot() is not defined, the corresponding
atomic*_fetch_andnot() is assumed to not be defined.
Additionally, the fallbacks for the various ordering cases are written
much later in atomic.h as static inlines.
This isn't problematic today, but gets in the way of scripting the
generation of atomics. To prepare for scripting, this patch:
* Switches to separate ifdefs for atomic*_andnot() and
atomic*_fetch_andnot(), updating implementations as appropriate.
* Moves the fallbacks into the standards ifdefs, as macro expansions
rather than static inlines.
* Removes trivial andnot implementations from architectures, where these
are superseded by core code.
There should be no functional change as a result of this patch.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
