It looks like Arnaldo's perf/core is progressing fast.

Currently I have this thing when building clean Arnaldo's perf/core:

  CC       tests/hists_output.o
In file included from util/session.c:26:
util/sample-raw.h:9:6: error: redundant redeclaration of perf_evlist__s390_sample_raw [-Werror=redundant-decls]
