Subject: [PATCH 0/5] perf tools: improve BPF related error delivering and testing

This patchset is based on Arnaldo's perf/core.

Patch 1/5 - 2/5 improve BPF related error delivering and reporting.
Libbpf and bpf-loader define their own error code sets so can
deliever precise reason of failure. Corresponding strerror functions
are improved accordingly.

Patch 3/5 - 5/5 improve 'perf test LLVM' and 'perf test BPF'. Code
structure improved so new test case can be introduced easier.

Wang Nan (5):
  bpf tools: Improve libbpf error reporting
  perf tools: Improve BPF related error messages output
  perf test: Enforce LLVM test: update basic BPF test program
  perf test: Enforce LLVM test: add kbuild test
  perf test: Add 'perf test BPF'
