Thomas Gleixner 0995a5dfbe tracing: Provide lockdep less trace_hardirqs_on/off() variants ... trace_hardirqs_on/off() is only partially safe vs. RCU idle. The tracer core itself is safe, but the resulting tracepoints can be utilized by e.g. BPF which is unsafe. Provide variants which do not contain the lockdep invocation so the lockdep and tracer invocations can be split at the call site and placed properly. This is required because lockdep needs to be aware of the state before switching away from RCU idle and after switching to RCU idle because these transitions can take locks. As these code pathes are going to be non-instrumentable the tracer can be invoked after RCU is turned on and before the switch to RCU idle. So for these new variants there is no need to invoke the rcuidle aware tracer functions. Name them so they match the lockdep counterparts.
