Now that all architectures provide arch_{atomic,atomic64}_*(), we can build arch_atomic_long_*() atop these, which can be safely used in noinstr code. The regular atomic_long_*() wrappers are built atop these, as we do for {atomic,atomic64}_*() atop arch_{atomic,atomic64}_*(). We don't provide arch_* versions of the cond_read*() variants, as we don't have arch_* versions of the underlying atomic/atomic64 functions (nor the smp_cond_load*() helpers these are typically based on). Note that the headers in this patch under include/linux/atomic/ are generated by the scripts in scripts/atomic/.

README
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.
