On x86_64 with gcc version 13.3.0, I compile kernel with:
make defconfig
./scripts/kconfig/merge_config.sh .config <(
echo CONFIG_COMPILE_TEST=y
)
make KCFLAGS="-fno-inline-functions -fno-inline-small-functions -fno-inline-functions-called-once"
Then I get a linker error:
ld: vmlinux.o: in function `pxp_fw_dependencies_completed':
kintel_pxp.c:(.text+0x95728f): undefined reference to `intel_pxp_gsccs_is_ready_for_sessions'
This is caused by not having a intel_pxp_gsccs_is_ready_for_sessions()
header stub for CONFIG_DRM_I915_PXP=n. Add it.

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.
