Now that the generic atomic headers provide instrumented wrappers of all
the atomics implemented by arm64, let's migrate arm64 over to these.
The additional instrumentation will help to find bugs (e.g. when fuzzing
with Syzkaller).
Mostly this change involves adding an arch_ prefix to a number of
function names and macro definitions. When LSE atomics are used, the
out-of-line LL/SC atomics will be named __ll_sc_arch_atomic_${OP}.
Adding the arch_ prefix requires some whitespace fixups to keep things
aligned. Some other unusual whitespace is fixed up at the same time
(e.g. in the cmpxchg wrappers).

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.
