#     
#     Pull perf tools fixes from Arnaldo Carvalho de Melo:
#     
#      - Prevent out-of-bounds access to per sample registers.
#     
#      - Fix NULL vs IS_ERR_OR_NULL() checking on the python binding.
#     
#      - Intel PT fixes, half of those are one-liners:
#           - Fix some PGE (packet generation enable/control flow packets) usage.
#           - Fix sync state when a PSB (synchronization) packet is found.
#           - Fix intel_pt_fup_event() assumptions about setting state type.
#           - Fix state setting when receiving overflow (OVF) packet.
#           - Fix next 'err' value, walking trace.
#           - Fix missing 'instruction' events with 'q' option.
#           - Fix error timestamp setting on the decoder error path.
