Subject: linux-next: manual merge of the oprofile tree with the tip tree

Hi Robert,

Today's linux-next merge of the oprofile tree got a conflict in
tools/perf/util/header.c tools/perf/util/header.h between commit
330aa675b4f9 ("perf record: Add HEADER_BRANCH_STACK tag") from the tip
tree and commit c415f577eb32 ("perf tools: Add pmu mappings to header
information") from the oprofile tree.

Just context changes.  I fixed it up (see below) and can carry the fix as
necessary.

Cheers,
