Now that all architectures provide arch_atomic_long_*(), we can implement the generic bitops atop these rather than atop atomic_long_*(), and provide arch_*() forms of the bitops that are safe to use in noinstr code. Now that all architectures provide arch_atomic_long_*(), we can build the generic arch_*() bitops atop these, which can be safely used in noinstr code. The regular bitop wrappers are built atop these. As the generic non-atomic bitops use plain accesses, these will be implicitly instrumented unless they are inlined into noinstr functions (which is similar to arch_atomic*_read() when based on READ_ONCE()). The wrappers are modified so that where the underlying arch_*() function uses a plain access, no explicit instrumentation is added, as this is redundant and could result in confusing reports. Since function prototypes get excessively long with both an `arch_` prefix and `__always_inline` attribute, the return type and function attributes have been split onto a separate line, matching the style of the generated atomic headers.

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.
