kmemtrace over tracepoints

Hi everybody,

As suggested by Mathieu Desnoyers, here's kmemtrace w/ tracepoints instead of markers. The RCU stuff has been giving me some headaches because of circular dependencies, but I think I've got it right.

I'm currently working on another thing Mathieu suggested, that is variable-length fields, so we don't waste space on non-64-bit arches.

Pekka, please merge this if it looks okay. I'll try to come up in time with the stuff described above; however, should I not be ready in time, please ask Linus to git-pull whatever we've got at present. Hopefully, it'll get in this time.

Alexey Dobriyan, please see if that problem you reported when kmemtrace was using markers is still there.

And (for everybody) please be kind and test and report whatever problems appear if possible.

Happy holidays,
Eduard

RCU: Move some definitions to minimal headers.
tracepoints: Include only minimal RCU headers in linux/tracepoint.h.
kmemtrace: Use tracepoints instead of markers.
