There are two variants of system_uses_lse_atomics(), depending on CONFIG_ARM64_LSE_ATOMICS. The function isn't called anywhere when CONFIG_ARM64_LSE_ATOMICS is disabled. It can be directly replaced by alternative_has_cap_likely(ARM64_HAS_LSE_ATOMICS) when the kernel option is enabled. No need to keep system_uses_lse_atomics() and just remove it.

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.
