This was already merged, see:

http://git.kernel.org/cgit/linux/kernel/git/tip/tip.git/log/tools?h=perf/core

More specifically:

http://git.kernel.org/cgit/linux/kernel/git/tip/tip.git/commit/tools?h=perf/core&id=70ba6b8f975bcff56e180e2c7550d2302fcbf923

So you can drop it from your patchset.

BTW, where are you basing your work?

If you do it over tip/perf/core you may find some of the trivial stuff
being added there, like this one.
