Thank you! 

It looks like it's been missed several times:
% find  tools/arch/arm64 -type f
tools/arch/arm64/include/uapi/asm/unistd.h
tools/arch/arm64/include/uapi/asm/bpf_perf_event.h
tools/arch/arm64/include/uapi/asm/kvm.h
tools/arch/arm64/include/uapi/asm/mman.h
tools/arch/arm64/include/uapi/asm/perf_regs.h
tools/arch/arm64/include/uapi/asm/bitsperlong.h
tools/arch/arm64/include/asm/barrier.h
tools/arch/arm64/include/asm/cputype.h
tools/arch/arm64/include/asm/sysreg.h

% grep arm64 tools/perf/check-headers.sh
arch/arm64/include/uapi/asm/perf_regs.h
arch/arm64/include/uapi/asm/kvm.h
arch/arm64/include/uapi/asm/unistd.h


Thanks,
