Subject: [PATCH v3 00/13] perf tools: BPF related update

This patch set is based on perf/core.

Compare with v2:
 - Checks return value of strdup()
 - Change BPF map setting syntax to 'maps:[mapname].[event:value]<indices>=value'
   For example:
     'maps:mapname.value[1,3...5]=10'
   Test cases in each commit message are also changed correspondingly.
   (Thanks to Namhyung Kim)

This patch set improves perf's BPF support:

 - Support filling BPF array with values
 
   Users are allowed to pass something to BPF program through command
   line without changing the program itself.

 - Support filling BPF event array with events

   BPF program can read PMU counters through BPF's perf_event_read()
   helper.

 - Support bpf_output_event() helper

   BPF program can issue perf event to perf.data.

In most of the patches I list commands for testing them, both normal
case and error case.

He Kuang (2):
  perf tools: Support perf event alias name
  perf record: Support custom vmlinux path

Wang Nan (11):
  tools lib bpf: Check return value of strdup when reading map names
  perf tools: Add API to config maps in bpf object
  perf tools: Enable BPF object configure syntax
  perf record: Apply config to BPF objects before recording
  perf tools: Enable passing event to BPF object
  perf tools: Support setting different slots in a BPF map separately
  perf tools: Enable indices setting syntax for BPF maps
  perf tools: Introduce bpf-output event
  perf data: Add u32_hex data type
  perf data: Support converting data from bpf_perf_event_output()
  perf tools: Always give options even it not compiled
