Note, I keep the non dynamic ftrace around for debugging purposes.
But sure, it's pretty useless. It's also good for bringing ftrace to a new architecture (like this patch is doing), as it is easier to implement than dynamic ftrace, and getting the non-dynamic working is usually the first step in getting dynamic ftrace working.
But it's really up to the arch maintainers to keep it or not.
