Merge tag 'perf-core-for-mingo' 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:

. perf build-id cache now can show DSOs present in a perf.data file that are
  not in the cache, to integrate with build-id servers being put in place by
  organizations such as Fedora.

. perf buildid-list -i an-elf-file-instead-of-a-perf.data is back showing its
  build-id.

. No need to do feature checks when doing a 'make tags'

. Fix some 'perf test' errors and make them use the tracepoint evsel constructor.

. perf top now shares more of the evsel config/creation routines with 'record',
  paving the way for further integration like 'top' snapshots, etc.

. perf top now supports DWARF callchains.

. perf evlist decodes sample_type and read_format, helping diagnose problems.

. Fix mmap limitations on 32-bit, fix from David Miller.

. perf diff fixes from Jiri Olsa.

. Ignore ABS symbols when loading data maps, fix from Namhyung Kim

. Hists improvements from Namhyung Kim

. Don't check configuration on make clean, from Namhyung Kim

. Fix dso__fprintf() print statement, from Stephane Eranian.
