Of course it is - didn't I say that too?

You're encountering the *exact* *same* issues I was fighting with. And I
was trying to save you that work because I did that conversion a couple
of times already! And hell yeah it is a *lot* of work! And a lot of
*wasted* work at that. Except maybe the fact that it gives you a rough
idea of what needs to be done.

So, for example, looka here:

http://lkml.kernel.org/r/20140612112534.GA24194@xxxxxxxxx

Borislav Petkov (4):
      perf tools: Move u64_swap union
      tools: Unify export.h
      tools: Consolidate types.h
      perf/events/core: Drop unused variable after cleanup

4 patches dealing with more or less one thing. No more. Once they're
accepted, you do another so many. And rinse and repeat.

And I've forwarded you the mails of how we want to split them with
Ingo's and acme's thoughts.

In any case, this is the only way I know of currently, which seems to
work right now with the amount of patches going into perf tool and with
the bandwidth of reviewers.

Additionally, if you'd like, we could sync among each other on who does
what. Maybe Robert would like to help too.

HTH.
