Merge tag 'perf-core-for-mingo-2' of... 

Merge tag 'perf-core-for-mingo-2' 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:

New features:

  - Add API to set values of map entries in a BPF object, be it
    individual map slots or ranges (Wang Nan)

  - Introduce support for the 'bpf-output' event (Wang Nan)

  - Add glue to read perf events in a BPF program (Wang Nan)

User visible changes:

  - Don't stop PMU parsing on alias parse error, allowing the
    addition of new sysfs PMU files without breaking old tools (Andi Kleen)

  - Implement '%' operation in libtraceevent (Daniel Bristot de Oliveira)

  - Allow specifying events via -e in 'perf mem record', also listing what events
    can be specified via 'perf mem record -e list' (Jiri Olsa)

  - Improve support to 'data_src', 'weight' and 'addr' fields in
    'perf script' (Jiri Olsa)

Infrastructure changes:

  - Export cacheline routines (Jiri Olsa)

  - Remove strbuf_{remove,splice}(), dead code (Arnaldo Carvalho de Melo)

Fixes:

  - Sort key fixes: Alignment for srcline, file, trace; fix
    segfault for dynamic, trace events related sort keys (Namyung Kim)

Build fixes:

  - Remove duplicate typedef config_term_func_t definition,
    fixing the build on older systems (Arnaldo Carvalho de Melo)
