Subject[RFC][PATCH 0/4] tracing/perf: Use helper functions to help shrink kernel size

I posted this a while ago (August 2012), and it seemed to have positive
feedback. But I forgot about it and it never went any further.

http://lkml.kernel.org/r/20120810034302.758092203@goodmis.org

It works to move the tracepoint code out of the macros and into reusable
functions that can save a whopping 73K from the kernel memory (with just the
modules I used compiled in).

There was some changes in mainline since I last posted this that helped
lower the tracepoint footprint, and that makes the first patch not as much
of an approvement that it was in the past.

Anyway, hopefully this can get into 3.15.
