Subject: [PATCH 0/4] KVM: x86/pmu: Clean up arch/hw event handling

Clean up KVM's handling of arch/hw events, and the related fixed counter
usage.  KVM has far too many open coded magic numbers, and kludgy code
that stems from the magic numbers.

Sean Christopherson (4):
  KVM: x86/pmu: Use enums instead of hardcoded magic for arch event
    indices
  KVM: x86/pmu: Simplify intel_hw_event_available()
  KVM: x86/pmu: Require nr fixed_pmc_events to match nr max fixed
    counters
  KVM: x86/pmu: Move .hw_event_available() check out of PMC filter
    helper
