Subject: [PATCH v1 0/3] KVM: selftests: aarch64: Introduce pmu_event_filter_test

The test is inspired by the pmu_event_filter_test which implemented by x86. On
the arm64 platform, there is the same ability to set the pmu_event_filter
through the KVM_ARM_VCPU_PMU_V3_FILTER attribute. So add the test for arm64.

The series first move some pmu common code from vpmu_counter_access to lib/
which can be used by pmu_event_filter_test. Then implements the test itself.

Shaoqin Huang (3):
  KVM: selftests: aarch64: Make the [create|destroy]_vpmu_vm() can be
    reused
  KVM: selftests: aarch64: Move the pmu helper function into lib/
  KVM: selftests: aarch64: Introduce pmu_event_filter_test
