Subject: [PATCH 0/2] Fix num_events calculation in lazy loading

I noticed "perf list" reported the error as follows on an Armv8 Neoverse
N2 server:
Unexpected event smmuv3_pmcg_3f062/smmuv3_pmcg_3f062/transaction//

The root cause is due to the incorrect calculation in
perf_pmu__num_events().

Jia He (2):
  perf pmu: Allow finishing loading json events when !events_table
  perf pmu: Fix num_events calculation
