  perf tools: Move new_term arguments into struct parse_events_term template
  perf build: Add special fixdep cleaning rule
  perf tools: Replace _SC_NPROCESSORS_CONF with max_present_cpu in cpu_topology_map
  perf header: Make build_cpu_topology skip offline/absent CPUs
  perf cpumap: Add cpu__max_present_cpu()
  perf session: Fix DEBUG=1 build with clang
