perf/core improvements and fixes:

perf trace: (Arnaldo Carvalho de Melo)
 
 - Do not require --no-syscalls to suppress strace like output, i.e.
 
      # perf trace -e sched:*switch
 
   will show just sched:sched_switch events, not strace-like formatted
   syscall events, use --syscalls to get the previous behaviour.
 
   If instead:
 
      # perf trace
 
   is used, i.e. no events specified, then --syscalls is implied and
   system wide strace like formatting will be applied to all syscalls.
 
   The behaviour when just a syscall subset is used with '-e' is unchanged:
 
      # perf trace -e *sleep,sched:*switch
 
   will work as before: just the 'nanosleep' syscall will be strace-like
   formatted plus the sched:sched_switch tracepoint event, system wide.
 
 - Allow string table generators to use a default header dir, allowing
   use of them without parameters to see the table it generates on
   stdout, e.g.:
 
     $ tools/perf/trace/beauty/kvm_ioctl.sh
     static const char *kvm_ioctl_cmds[] = {
         [0x00] = "GET_API_VERSION",
         [0x01] = "CREATE_VM",
         [0x02] = "GET_MSR_INDEX_LIST",
         [0x03] = "CHECK_EXTENSION",
 <BIG SNIP>
         [0xe0] = "CREATE_DEVICE",
         [0xe1] = "SET_DEVICE_ATTR",
         [0xe2] = "GET_DEVICE_ATTR",
         [0xe3] = "HAS_DEVICE_ATTR",
     };
     $
 
   See 'ls tools/perf/trace/beauty/*.sh' to see the available string
   table generators.
 
 - Add a generator for IPPROTO_ socket's protocol constants.
 
 perf record: (Kan Liang)
 
 - Fix error out while applying initial delay and using LBR, due to
   the use of a PERF_TYPE_SOFTWARE/PERF_COUNT_SW_DUMMY event to track
   PERF_RECORD_MMAP events while waiting for the initial delay. Such
   events fail when configured asking PERF_SAMPLE_BRANCH_STACK in
   perf_event_attr.sample_type.
 
 perf c2c: (Jiri Olsa)
 
 - Fix report crash for empty browser, when processing a perf.data file
   without events of interest, either because not asked for in
   'perf record' or because the workload didn't triggered such events.
 
 perf list: (Michael Petlan)
 
 - Align metric group description format with PMU event description.
 
 perf tests: (Sandipan Das)
 
 - Fix indexing when invoking subtests, which caused BPF tests to
   get results for the next test in the list, with the last one
   reporting a failure.
 
 eBPF:
 
 - Fix installation directory for header files included from eBPF proggies,
   avoiding clashing with relative paths used to build other software projects
   such as glibc. (Thomas Richter)
 
 - Show better message when failing to load an object. (Arnaldo Carvalho de Melo)
 
 General: (Christophe Leroy)
 
 - Allow overriding MAX_NR_CPUS at compile time, to make the tooling
   usable in systems with less memory, in time this has to be changed
   to properly allocate based on _NPROCESSORS_ONLN.
 
 Architecture specific:
 
 - Update arm64's ThunderX2 implementation defined pmu core events (Ganapatrao Kulkarni)
 
 - Fix complex event name parsing in 'perf test' for PowerPC, where the 'umask' event
   modifier isn't present. (Sandipan Das)
 
 CoreSight ARM hardware tracing: (Leo Yan)
 
 - Fix start tracing packet handling.
 
 - Support dummy address value for CS_ETM_TRACE_ON packet.
 
 - Generate branch sample when receiving a CS_ETM_TRACE_ON packet.
 
 - Generate branch sample for CS_ETM_TRACE_ON packet.
