On ppc64le we get the following warning:
In file included from btf_dump.c:16:0:
btf_dump.c: In function ‘btf_dump_emit_struct_def’:
../include/linux/kernel.h:20:17: error: comparison of distinct pointer types lacks a cast [-Werror]
(void) (&_max1 == &_max2); \
^
btf_dump.c:882:11: note: in expansion of macro ‘max’
m_sz = max(0LL, btf__resolve_size(d->btf, m->type));
^~~
Fix by explicitly casting to __s64, which is a return type from
btf__resolve_size().

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.
