The comment in 'asm-generic/bitops.h' states that you should "recode these in the native assembly language, if at all possible". This is pretty crappy advice now that the generic implementation is defined in terms of atomic_long_t rather than a spinlock, so update the comment and hopefully save future architecture maintainers a bit of work.

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.
