perf/core improvements and fixes:

Browse Source 
perf top:
 
   Namhyung Kim:
 
   - Decay all events in the evlist, we were decaying just the first event
     in a group.
 
   - Fix linking of histograms in different evsels in a event group with more
     than two events.
 
   With the two fixes above a command line such as:
 
     # perf top -e '{cycles,instructions,cache-misses,cache-references}
 
     Should work as expected, with four columns and with all of them being
     decayed over time, i.e. less weight is given for older samples.
 
 perf record:
 
   Arnaldo Carvalho de Melo:
 
   - Fix collection of build-ids when using setns() to get into namespaces,
     which had been broken with the introduction of the extra thread to
     react to PERF_RECORD_BPF_EVENT, i.e. to collect extra info for BPF
     programs. We need to unshare(CLONE_FS) in that thread so that the
     main one can do the setns(CLONE_NEWNS) when collectingthe build-ids.
     Without that symbol resolution gets more difficult and potentially
     misresolves symbols.
 
 core:
 
   Igor Lubashev:
 
   - Further alignment in permission checking via capabilities to how the
     kernel checks what tooling tries to do.
 
 PowerPC:
 
   Naveen N. Rao:
 
   - Sync powerpc syscall.tbl, so that 'perf trace' gets the definitions
     for recent syscalls.
 
 libperf:
 
   Jiri Olsa:
 
   - Move the rest of the PERF_RECORD_ metadata struct definitions so that
     we can use 'union perf_event'.
 
 libtraceevent:
 
   Steven Rostedt (VMware):
 
   - Do not free tep->cmdlines in add_new_comm() on failure.
 
   - Remove unneeded qsort and uses memmove instead
