 tagger Arnaldo Carvalho de Melo <acme@redhat.com> 1465328341 -0300
 
 perf/core improvements and fixes:
 
 User visible:
 
 - 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:
 
 - 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)
