Subject: [PATCH] perf vendor events: Add Arm Neoverse V2 PMU events
Rename the neoverse-n2 folder to make it clear that it includes V2, and
add V2 to mapfile.csv. V2 has the same events as N2, visible by running
the following command in the ARM-software/data github repo [1]:
diff pmu/neoverse-v2.json pmu/neoverse-n2.json | grep code
Testing:
$ perf test pmu
10: PMU events :
10.1: PMU event table sanity : Ok
10.2: PMU event map aliases : Ok
10.3: Parsing of PMU event table metrics : Ok
10.4: Parsing of PMU event table metrics with fake PMUs : Ok
