Subject: [PATCH v1 0/3] perf arm-spe: Correct recording configurations

This patch series is to correct Arm SPE recording configurations.

As found by James Clark, it's not reasonable for the current code for
sample flags CPU/TIME/TID which are hard coded.  For TIME sample flag,
since it's always enabled, then Arm SPE has no chance for timeless
tracing; for CPU sample flag, it's not needed for per-thread mode;
for TID sample flag, it's redundant for AUX and dummy events.

This series corrects the sample flags setting, and it enables
timestamp for per-cpu mode tracing by default.

This patch set has been tested on Arm64 Hisilicon D06 platform.

  perf arm-spe: Correct sample flags for dummy event
  perf arm-spe: Enable timestamp for per-cpu mode
