Subject: [PATCH 0/5] perf tools: Store CPU cache details under perf data

hi,
adding support to store CPU cache details under perf data. 

  $ perf report --header-only -I
  ...
  # cache info:
  #  L1 Data 32K [0-1]
  #  L1 Instruction 32K [0-1]
  #  L1 Data 32K [2-3]
  #  L1 Instruction 32K [2-3]
  #  L2 Unified 256K [0-1]
  #  L2 Unified 256K [2-3]
  #  L3 Unified 4096K [0-3]
  ...

Plus some libapi additions.
