OK, then I'll resend my patch. I tested it with build bots against
various architectures and configs, so I believe it's complete.

Your version includes trace_printk.h in linux/trace.h. It looks
reasonable, and it allows to drop explicit trace_printk.h
inclusion from:
  - kernel/trace/trace.c;
  - kernel/trace/trace_events_trigger.c;
  - kernel/trace/trace_functions.c;
  - kernel/trace/trace_printk.c.

With that, the total number of files including the trace_printk.h 
is 30, which looks reasonable.

I need a couple days to get feedback from build bots, so not sure I'll
submit it before the end of the week.

If somebody wants to give it a try, check here:
