[PATCH v19 01/11] perf: arm_pmuv3: Call kvm_vcpu_pmu_resync_el0() before enabling counters

[Rob Herring (Arm)]

Counting events related to setup of the PMU is not desired, but
kvm_vcpu_pmu_resync_el0() is called just after the PMU counters have
been enabled. Move the call to before enabling the counters.
