Subject: [GIT PULL] perf callchain improvement and fixes

Ingo,

Please pull the perf/core branch that can be found at:

git://git.kernel.org/pub/scm/linux/kernel/git/frederic/random-tracing.git
	perf/core

Unfortunately we were missing a lot of callchains in multithread
cases. And this was not a regression, it was rather the fact I
was missing a part of the histogram processing: the collapsing.

Anyway, this is eventually fixed. Thanks a lot to Chistoph Hellwig
who reported this.

Thanks,
	Frederic
