A perf build failure was reported by Thomas Voegtle on stable kernel
v6.6.120:

Fix this by including linux/kernel.h, which provides the required
definitions.
The issue was not found on the mainline due to the relevant C files have
included kernel.h. It'd be good to merge this change on mainline
as well for robustness.
Closes: https://lore.kernel.org/stable/3a44500b-d7c8-179f-61f6-e51cb50d3512@lio96.de/
