Thanks, applied, I made a few changes, related to libtraceevent function
names, split a patch in two, please take a look at my perf/core branch,
should all be ok.

Ah, please consider looking for field names directly, i.e. make this
work for a kmem:kmalloc event:

    perf report -s comm,gfp_flags

:-)

I think this can get mapped even when multiple events are available,
i.e. use that for the events that have such a field.

It could even get more relaxed, like:

    perf report -s comm,flags

No?
