Mark Rutland 9fa45070a2 locking/atomics: Switch to generated fallbacks
As a step to ensuring the atomic* APIs are consistent, switch to fallbacks
generated by gen-atomic-fallback.sh.

These are checked in rather than generated with Kbuild, since:

* This allows inspection of the atomics with git grep and ctags on a
  pristine tree, which Linus strongly prefers being able to do.

* The fallbacks are not affected by machine details or configuration
  options, so it is not necessary to regenerate them to take these into
  account.

* These are included by files required *very* early in the build process
  (e.g. for generating bounds.h), and we'd rather not complicate the
  top-level Kbuild file with dependencies.

The new fallback header should be equivalent to the old fallbacks in
<linux/atomic.h>, but:

* It is formatted a little differently due to scripting ensuring things
  are more regular than they used to be.

* Fallbacks are now expanded in-place as static inline functions rather
  than macros.

* The prototypes for fallbacks are arragned consistently with the return
  type on a separate line to try to keep to a sensible line length.

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.
