Yeah, reproduced:

We shouldn't be ever using anything outside tools, but over time we
ended up doing that :-(

And its just arm64 that is getting things from outside tools/

⬢ [acme@toolbx perf-tools]$ head tools/perf/MANIFEST 
COPYING
LICENSES/preferred/GPL-2.0
arch/arm64/tools/gen-sysreg.awk
arch/arm64/tools/syscall_64.tbl
arch/arm64/tools/sysreg
arch/*/include/uapi/asm/bpf_perf_event.h
include/uapi/asm-generic/Kbuild
tools/perf
tools/arch
tools/scripts
⬢ [acme@toolbx perf-tools]$

James, has this appeared on your radar before?
