Merge tag 'perf-core-for-mingo-20160607' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core
Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo:
User visible changes:
- Support cross unwinding, i.e. collecting '--call-graph dwarf' perf.data files
in one machine and then doing analysis in another machine of a different
hardware architecture. This enables, for instance, to do:
perf record -a --call-graph dwarf
on a x86-32 or aarch64 system and then do 'perf report' on it on a
x86_64 workstation. (He Kuang)
- Fix crash in build_id_cache__kallsyms_path(), recent regression (Wang Nan)
Infrastructure changes:
- Make tools/lib/bpf use the IS_ERR return facility consistently and also stop
using the _get_ term for non-reference count methods (Arnaldo Carvalho de Melo)
- 'perf config' refactorings (Taeung Song)
