Merge tag 'perf-core-for-mingo-4.19-20180815' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent

Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo:

kernel:

- kallsyms, x86: Export addresses of PTI entry trampolines (Alexander Shishkin)

- kallsyms: Simplify update_iter_mod() (Adrian Hunter)

- x86: Add entry trampolines to kcore (Adrian Hunter)

Hardware tracing:

- Fix auxtrace queue resize (Adrian Hunter)

Arch specific:

- Fix uninitialized ARM SPE record error variable (Kim Phillips)

- Fix trace event post-processing in powerpc (Sandipan Das)

Build:

- Fix check-headers.sh AND list path of execution (Alexander Kapshuk)

- Remove -mcet and -fcf-protection when building the python binding
  with older clang versions (Arnaldo Carvalho de Melo)

- Make check-headers.sh check based on kernel dir (Jiri Olsa)

- Move syscall_64.tbl check into check-headers.sh (Jiri Olsa)

Infrastructure:

- Check for null when copying nsinfo.  (Benno Evers)

Libraries:

- Rename libtraceevent prefixes, prep work for making it a shared
  library generaly available (Tzvetomir Stoyanov (VMware))

--group::
Show event group information together
--percent-type::
Set annotation percent type from following choices:
global-period, local-period, global-hits, local-hits
The local/global keywords set if the percentage is computed
in the scope of the function (local) or the whole data (global).
The period/hits keywords set the base the percentage is computed
on - the samples period or the number of samples (hits).
