In this header every cmpxchg define (_relaxed, _acquire, _release, vanilla) contain it's own asm file, both for 4-byte variables an 8-byte variables, on a total of 8 versions of mostly the same asm. This is usually bad, as it means any change may be done in up to 8 different places. Unify those versions by creating a new define with enough parameters to generate any version of the previous 8. Then unify the result under a more general define, and simplify arch_cmpxchg* generation (This did not cause any change in generated asm) Signed-off-by: Leonardo Bras <leobras@redhat.com> Reviewed-by: Guo Ren <guoren@kernel.org> Reviewed-by: Andrea Parri <parri.andrea@gmail.com> Tested-by: Guo Ren <guoren@kernel.org> Link: https://lore.kernel.org/r/20240103163203.72768-4-leobras@redhat.com Signed-off-by: Palmer Dabbelt <palmer@rivosinc.com>
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.
