Subject: [PATCH v4 net-next 0/3] bpf: Add BPF support to all perf_event

v3->v4: one more tweak to reject unsupported events at map
update time as Peter suggested

v2->v3: more refactoring to address Peter's feedback.
Now all perf_events are attachable and readable

v1->v2: address Peter's feedback. Refactor patch 1 to allow attaching
bpf programs to all event types and reading counters from all of them as well
patch 2 - more tests
patch 3 - address Dave's feedback and document bpf_perf_event_read()
and bpf_perf_event_output() properly

Alexei Starovoitov (1):
  perf, bpf: Add BPF support to all perf_event types

Teng Qin (2):
  samples/bpf: add tests for more perf event types
  bpf: update perf event helper functions documentation
