[PATCH 0/1] Perf: fix overwritten of free running PEBSv3 timestamp

[Tong Zhang]

Hi,
  commit a7b58d211ba18c9175b139e18b68c86a6bcc3c3f introduced
  feature of timestamp on free running PEBSv3, however,
  the timestamp is later overwritten, which makes the effort in vain.

  This patch prevent overwritten by detecting whether
  a timestamp is provided.
