Alan Stern bf28ae5627 tools/memory-model: Remove rb-dep, smp_read_barrier_depends, and lockless_dereference
Since commit 76ebbe78f7 ("locking/barriers: Add implicit
smp_read_barrier_depends() to READ_ONCE()") was merged for the 4.15
kernel, it has not been necessary to use smp_read_barrier_depends().
Similarly, commit 59ecbbe7b3 ("locking/barriers: Kill
lockless_dereference()") removed lockless_dereference() from the
kernel.

Since these primitives are no longer part of the kernel, they do not
belong in the Linux Kernel Memory Consistency Model.  This patch
removes them, along with the internal rb-dep relation, and updates the
revelant documentation.

README

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

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.
