When CONFIG_BUILTIN_MODULE_RANGES is enabled, the modules.builtin.ranges
file should be installed in the module install location.

Notes:
Changes since v3:

The offset range data for builtin modules is generated using:
- modules.builtin: associates object files with module names
- vmlinux.map: provides load order of sections and offset of first member

The modules.builtin.ranges offset range data for builtin modules is

In order to be able to identify what code is compiled into modules (even
built-in modules) during a kernel build, one can look for the presence
of the -DKBUILD_MODFILE and -DKBUILD_MODNAME options in the compile
command lines. A simple grep in .*.cmd files for those options is
sufficient for this.
Especially for tracing applications, it is convenient to be able to
refer to a symbol using a pair and to be able
to translate an address into a pair. But
that does not work if the module is built into the kernel because the

As nonseekable_open() documentation states:
"The function is not supposed to ever fail, the only
reason it returns an 'int' and not 'void' is so that it can be plugged
directly into file_operations structure."
