Subject: [PATCH 0/5] perf: add two new features

Hi

Please consider these two new perf features:
      x86: add ability to calculate TSC from perf sample timestamps
      perf: add 'keep tracking' flag to PERF_EVENT_IOC_DISABLE

This is also a minor fix:
      perf: fix broken union in perf_event_mmap_page

And tests in perf tools:
      perf tools: add test for converting perf time to/from TSC
      perf tools: add 'keep tracking' test
