If CONFIG_ELF_CORE is not set:
fs/coredump.c:835:12: error: ‘dump_emit_page’ defined but not used [-Werror=unused-function]
835 | static int dump_emit_page(struct coredump_params *cprm, struct page *page)
| ^~~~~~~~~~~~~~
Fix this by moving dump_emit_page() inside the existing section
protected by #ifdef CONFIG_ELF_CORE.
Fixes: 06bbaa6dc5 ("[coredump] don't use __kernel_write() on kmap_local_page()")

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.
