Currently for reasons lost in the mists of time the kernel_neon_ APIs are EXPORT_SYMBOL() but the general policy for floating point usage is that it should be GPL only given the non-standard runtime environment that holds while it is in use and PCS impacts when code is compiled for FP usage. Given the limited existing deployment of non-GPL modules for arm64 and the fact that other architectures like x86 already make their equivalent functions GPL only this is not expected to be disruptive to existing users.

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.
