For people who would like to test this series, compilation may be
broken in the middle of the series (probably at the 3rd patch and
fixed at the last patch) if your toolchain provides old linux kernel
headers.
This is an issue I hit myself when testing cross compilation on ppc
with a 2022 toolchain provided by bootlin.
Upgrading the toolchain solved this.
