Merge tag 'perf-core-for-mingo-5.3-20190703' 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 metrics:

  Andi Kleen:

  - Fixes for SkylakeX and CascadeLakeX Intel vendor events.

  - Avoid extra ':' for --raw metrics.

  - Don't include duration_time in group.

perf script:

  Arnaldo Carvalho de Melo/Jiri Olsa:

  - Fix processing guest samples.

perf diff:

  Jin Yao:

  - Do diffs by basic blocks.

objtool:

  Jiri Olsa:

  - Fix build by linking against tools/lib/ctype.o sources.

perf pmu:

  John Garry:

  - Support more complex PMU event aliasing.

  - Add support for Hisi hip08 DDRC, HHA and L3C PMU aliasing.
