perf/core improvements and fixes:

Browse source 
Fixes:
 
 - Fix concat_probe_trace_events() in 'perf probe', it should dereference a
   pointer, not test its value (Ravi Bangoria)
 
 User visible:
 
 - Handle partial AUX records, checking if 'kvm_intel.ko' is loaded and
   if its 'vmm_exclusive' parameter is set to 0, suggesting tweaking
   it to reduce gaps (Alexander Shishkin)
 
 Infrastructure:
 
 - Sync the kvm.h, cpufeatures.h and perf_event.h tools/ headers copies
   with the kernel (Arnaldo Carvalho de Melo, Alexander Shishkin)
 
 - 'perf lock' subcommands should include common options, using
   OPT_PARENT() (Changbin Du)
 
 - Ditto for 'perf timechart' (Arnaldo Carvalho de Melo)
 
 Documentation:
 
   Correct 'perf stat --no-aggr' description (Ravi Bangoria)
