  perf tests bpf: Use SyS_epoll_wait alias (2016-08-03 19:40:48 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

New features:

- Add --sample-cpu to 'perf record', to explicitely ask for sampling
  the CPU (Jiri Olsa)

Fixes:

- Fix processing of multi byte chunks in objdump output, fixing
  disassemble processing for annotation on at least ARM64 (Jan Stancek)

- Use SyS_epoll_wait in a BPF 'perf test' entry instead of sys_epoll_wait, that
  is not present in the DWARF info in vmlinux files (Arnaldo Carvalho de Melo)

- Add -wno-shadow when processing files using perl headers, fixing
  the build on Fedora Rawhide and Arch Linux (Namhyung Kim)

Infrastructure:

- Annotate prep work to better catch and report errors related to
  using objdump to disassemble DSOs (Arnaldo Carvalho de Melo)

- Add 'alloc', 'scnprintf' and 'and' methods for bitmap processing (Jiri Olsa)

- Add nested output resorting callback in hists processing (Jiri Olsa)
