[ Upstream commit a537c0da168a08b0b6a7f7bd9e75f4cc8d45ff57 ]
A perf build failure was reported by Thomas Voegtle on stable kernel
v6.6.120:
CC tests/sample-parsing.o
CC util/intel-pt-decoder/intel-pt-pkt-decoder.o
CC util/perf-regs-arch/perf_regs_csky.o
CC util/arm-spe-decoder/arm-spe-pkt-decoder.o

__MAKE_OP(16)
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/
