When building for a 32-bit platform, there are some warnings (or errors
with CONFIG_WERROR=y) due to an incorrect specifier for 'size_t'
variables, which is typedef'd as 'unsigned int' for these architectures:
drivers/gpu/drm/tiny/appletbdrm.c:171:17: error: format specifies type 'unsigned long' but the argument has type 'size_t' (aka 'unsigned int') [-Werror,-Wformat]
170 | drm_err(drm, "Actual size (%d) doesn't match expected size (%lu)\n",
| ~~~
| %zu
171 | actual_size, size);
| ^~~~
...
drivers/gpu/drm/tiny/appletbdrm.c:212:17: error: format specifies type 'unsigned long' but the argument has type 'size_t' (aka 'unsigned int') [-Werror,-Wformat]
211 | drm_err(drm, "Actual size (%d) doesn't match expected size (%lu)\n",
| ~~~
| %zu
212 | actual_size, size);
| ^~~~
Use '%zu' as suggested, clearing up the warnings.

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.
