Merge branch 'kvm-arm64/pmuv3-asahi' into kvmarm/next

* kvm-arm64/pmuv3-asahi:
  : Support PMUv3 for KVM guests on Apple silicon
  :
  : Take advantage of some IMPLEMENTATION DEFINED traps available on Apple
  : parts to trap-and-emulate the PMUv3 registers on behalf of a KVM guest.
  : Constrain the vPMU to a cycle counter and single event counter, as the
  : Apple PMU has events that cannot be counted on every counter.
  :
  : There is a small new interface between the ARM PMU driver and KVM, where
  : the PMU driver owns the PMUv3 -> hardware event mappings.
  arm64: Enable IMP DEF PMUv3 traps on Apple M*
  KVM: arm64: Provide 1 event counter on IMPDEF hardware
  drivers/perf: apple_m1: Provide helper for mapping PMUv3 events
  KVM: arm64: Remap PMUv3 events onto hardware
  KVM: arm64: Advertise PMUv3 if IMPDEF traps are present
  KVM: arm64: Compute synthetic sysreg ESR for Apple PMUv3 traps
  KVM: arm64: Move PMUVer filtering into KVM code
  KVM: arm64: Use guard() to cleanup usage of arm_pmus_lock
  KVM: arm64: Drop kvm_arm_pmu_available static key
  KVM: arm64: Use a cpucap to determine if system supports FEAT_PMUv3
  KVM: arm64: Always support SW_INCR PMU event
  KVM: arm64: Compute PMCEID from arm_pmu's event bitmaps
  drivers/perf: apple_m1: Support host/guest event filtering
  drivers/perf: apple_m1: Refactor event select/filter configuration
