eBPF "restricted C" code can be compiled with LLVM/clang using target triplets like armv7l-unknown-linux-gnueabihf and loaded/run with small cross-compiled gobpf/elf [1] programs without requiring a full BCC port which is also undesirable on small embedded systems due to its size footprint. The only missing pieces are these helper macros which otherwise have to be redefined by each eBPF arm program.

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.
