Ooops. No!
I just read back and noticed that this is a report against some whatever kernel:

# cd linus/linux # gcur master 2c71fdf02a95: Merge tag 'drm-fixes-2024-04-09' of https://gitlab.freedesktop.org/drm/kernel # git grep generic_processor_info #
generic_processor_info() was removed during the 6.9 merge window with the topology rework before v6.9-rc1.
So the guest kernel _cannot_ be v6.9-rc2 at all.
