Rework atomic.h into permissive.h to better reflect its purpose, and introduce kcsan_ignore_address() and kcsan_ignore_data_race(). Introduce CONFIG_KCSAN_PERMISSIVE and update the stub functions in preparation for subsequent changes. As before, developers who choose to use KCSAN in "strict" mode will see all data races and are not affected. Furthermore, by relying on the value-change filter logic for kcsan_ignore_data_race(), even if the permissive rules are enabled, the opt-outs in report.c:skip_report() override them (such as for RCU-related functions by default). The option CONFIG_KCSAN_PERMISSIVE is disabled by default, so that the documented default behaviour of KCSAN does not change. Instead, like CONFIG_KCSAN_IGNORE_ATOMICS, the option needs to be explicitly opted in.

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.
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.
