perf test:
- Add watchpoint entry (Ravi Bangoria)
Build fixes:
- Initialize perf_data_file fd field to fix building the CTF (trace format)
converter with with gcc 4.8.4 on Ubuntu 14.04 (Jérémie Galarneau)
- Use -Wno-redundant-decls to build with PYTHON=python3 to
build the python binding, fixing the build in systems such
as Clear Linux (Arnaldo Carvalho de Melo)
Hardware tracing:
- Suppress AUX/OVERWRITE records (Alexander Shishkin)
Infrastructure:
- Adopt PTR_ERR_OR_ZERO from the kernel and use it in
the bpf-loader instead of open coded equivalent (Ding Xiang)
- Improve the event ordering code to make it clear and fix
a bug related to freeing of events when using pipe mode
from 'record' to 'inject' (Jiri Olsa)
- Some prep work to facilitate per-cpu threads to write
record data to per-cpu files (Jiri Olsa)
