On arm32, 'cd tools/testing/selftests/bpf && make' fails with:
libbpf.c:80:10: error: format ‘%ld’ expects argument of type ‘long int’, but argument 4 has type ‘int64_t {aka long long int}’ [-Werror=format=]
(func)("libbpf: " fmt, ##__VA_ARGS__); \
^
libbpf.c:83:30: note: in expansion of macro ‘__pr’
#define pr_warning(fmt, ...) __pr(__pr_warning, fmt, ##__VA_ARGS__)
^~~~
libbpf.c:1072:3: note: in expansion of macro ‘pr_warning’
pr_warning("map:%s value_type:%s has BTF type_size:%ld != value_size:%u\n",
To fix, typecast 'key_size' and amend format string.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
