looks like you're missing this one:
(git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux perf/core)

perf tools: Add default handler for mmap2 events
commit e0e3e2d9a522b2230d395922fde9c6ea928ae7f8
Author: David Ahern <dsahern@...il.com>
Date:   Sun Sep 22 19:44:59 2013 -0600

Not sure if this one plus some other MMAP2 David's fixies
are on its way up, but if not I guess Arnaldo's planning
to push them out eventually ;-)
