This series adds support for counting PMU events using 64bit counters for arm64 PMU. The Arm v8 PMUv3 supports combining two adjacent 32bit counters (low even and hig odd counters) to count a given "event" in 64bit mode. This series adds the support for 64bit events in the core arm_pmu driver infrastructure and adds the support for armv8 64bit kernel PMU to use chained counters to count in 64bit mode. For CPU cycles, we use the cycle counter in 64bit mode, when requested. If the cycle counter is not available, we fall back to chaining the counters. Tested on Juno, Fast models. Applies on 4.17-rc4
