Hmm, do we really want to do that?

We really need to get the perf and ftrace trace buffers combined. I
understand why perf chose to do the mmap buffers for the counting, but
for live streaming, it is very inefficient compared to splice.

I would hate to add more duplicate code to have perf support
trace_printk().
