vmlinux.o: warning: objtool: intel_idle_irq+0x10c: call to trace_hardirqs_off() leaves .noinstr.text section As per commit 32d4fd5751ea ("cpuidle,intel_idle: Fix CPUIDLE_FLAG_IRQ_ENABLE"): "must not have tracing in idle functions" Clearly people can't read and tinker along until splat dissapears. This straight up reverts commit d295ad34f236 ("intel_idle: Fix false positive RCU splats due to incorrect hardirqs state"). It doesn't re-introduce the problem because preceding patches fixed it properly.
