Merge tag 'perf-core-for-mingo-5.3-20190621' 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 trace:

  Arnaldo Carvalho de Melo:

  - Fix exclusion of not available syscall names from selector list.

  - Fixup pointer arithmetic when consuming augmented syscall args.

Intel PT:

  Adrian Hunter:

  - Add support for decoding PEBS via PT packets. See:

      https://software.intel.com/en-us/articles/intel-sdm


      May 2019 version: Vol. 3B 18.5.5.2 PEBS output to Intel® Processor Trace

  for more details about it.

ARM64:

  John Garry:

  - Fix uncore PMU alias list for ARM64

  Raphael Gault:

  - Compile tests unconditionally.

cs-etm:

  Mathieu Poirier:

  - Optimize option setup for CPU-wide sessions.

build:

  Florian Fainelli:

  - Don't hardcode host include path for libslang, fixing up building with it
    in cross build environments.

  Arnaldo Carvalho de Melo:

  - Check if gettid() is available before providing helper, fixing the build
    when using the latest glibc version, where a helper for gettid() is finally
    present.

  - Fix building with libslang in systems where it is located in slang/slang.h.

  - Fix fast path test for zstd library.
