U64_MAX is not in include/vdso/limits.h, although that isn't noticed on x86
because x86 includes include/linux/limits.h indirectly. However powerpc is
more selective, resulting in the following build error:
In file included from <command-line>:
lib/vdso/gettimeofday.c: In function 'vdso_calc_ns':
lib/vdso/gettimeofday.c:11:33: error: 'U64_MAX' undeclared
11 | # define VDSO_DELTA_MASK(vd) U64_MAX
| ^~~~~~~
Use ULLONG_MAX instead which will work just as well and is in
include/vdso/limits.h.

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 reStructuredText 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.
