This patch set is to enable timestamp for Arm SPE trace.  It reads out
TSC parameters from the TIME_CONV event, the parameters are used for
conversion between timer counter and kernel time, the calculated
timestamps are assigned to Arm SPE samples.

This patch set can be clearly applied on perf/core branch with:

  commit 046b243a6afb ("perf x86 kvm-stat: Support to analyze kvm MSR")

The patches have been tested on Hisilicon D06 platform.

Changes from v4:
* Dropped the change "perf arm-spe: Remove unused enum value
  ARM_SPE_PER_CPU_MMAPS" for format compatibility (James).

Changes from v3:
* Let to be backwards-compatible for TIME_CONV event (Adrian).

Changes from v2:
* Changed to use TIME_CONV event for extracting clock parameters (Al).

Changes from v1:
* Rebased patch series on the latest perf/core branch;
* Fixed the patch for dumping TSC parameters to support both the
  older and new auxtrace info format.


Leo Yan (5):
  perf arm-spe: Save clock parameters from TIME_CONV event
  perf arm-spe: Convert event kernel time to counter value
  perf arm-spe: Assign kernel time to synthesized event
  perf arm-spe: Bail out if the trace is later than perf event
  perf arm-spe: Don't wait for PERF_RECORD_EXIT event
