Well, if Sam and Michal are fine with it I'm a happy camper.

One question. Instead of:

  make tools/perf_install

Couldnt we beat kbuild into submission to allow the much more 
obvious:

  make tools/perf install

?

I don't think anyone would expect the *kernel* to be installed 
in such a circumstance - so it's only a question of making the 
Makefile understand it, right?

Thanks,
