Seeteena Thoufeek fad76d4333 perf script: Show hw-cache events 
'perf script' fails to report hardware cache events (PERF_TYPE_HW_CACHE)
where as 'perf report' shows the samples. Fix it. Ex,

  # perf record -e L1-dcache-loads ./a.out
  [ perf record: Woken up 1 times to write data ]
  [ perf record: Captured and wrote 0.008 MB perf.data (11 samples)]

Before patch:

  # perf script | wc -l
  0

After patch:

  # perf script | wc -l
  11
