This patch series is to enable multiple Arm SPE PMUs.

The patch 01 is to enable multiple Arm SPE PMUs. The second patch is to
print out warning if not all CPUs support memory events, this can give
users a hint that the memory profiling is absent on some CPUs.


Leo Yan (2):
  perf arm-spe: Support multiple Arm SPE PMUs
  perf mem: Warn if memory events are not supported on all CPUs
