Per 408b961146be ("tracing: WARN on rcuidle")
and git grep "select.*ARCH_WANTS_NO_INSTR"
arch/arm64/Kconfig: select ARCH_WANTS_NO_INSTR
arch/loongarch/Kconfig: select ARCH_WANTS_NO_INSTR
arch/riscv/Kconfig: select ARCH_WANTS_NO_INSTR
arch/s390/Kconfig: select ARCH_WANTS_NO_INSTR
arch/x86/Kconfig: select ARCH_WANTS_NO_INSTR

I'm thinking you can simply use that same condition here?
