Merge tag 'perf-core-for-mingo-5.5-20191112' 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 record:

  Ravi Bangoria:

  - Provide an option to print perf_event_open args and syscall return value.
    This was already possible using -v, but then lots of other debug info
    would be output as well, provide a way to show just the syscall args
    and return value, e.g.:

      # perf --debug perf-event-open=1 record
      perf_event_attr:
        size                             112
        { sample_period, sample_freq }   4000
        sample_type                      IP|TID|TIME|PERIOD
        read_format                      ID
        disabled                         1
        inherit                          1
      <SNIP>
        ksymbol                          1
        bpf_event                        1
      ------------------------------------------------------------
      sys_perf_event_open: pid 4308  cpu 0  group_fd -1  flags 0x8 = 4

core:

- Remove map->groups, we can get that information in other ways, reduces
  the size of a key data structure and paves the way to have it shared
  by multiple threads.

- Use 'struct map_symbol' in more places, where we already were using a
  'struct map' + 'struct symbol', this helps passing that usual pair of
  information across callchain, browser code, etc.

- Add 'struct map_groups' (where the map_symbol->map is) to 'struct map_symbol',
  to ease annotation code, for instance, where we call from functions in one map
  we're browsing to functions in another DSO, mapped in another 'struct map'.

event parsing:

  Ian Rogers:

  - Use YYABORT to clear stack after failure, plugging leaks
