Merge branch kvm-arm64/sgi-injection into kvmarm/next

Browse Source 
* kvm-arm64/sgi-injection:
  : vSGI injection improvements + fixes, courtesy Marc Zyngier
  :
  : Avoid linearly searching for vSGI targets using a compressed MPIDR to
  : index a cache. While at it, fix some egregious bugs in KVM's mishandling
  : of vcpuid (user-controlled value) and vcpu_idx.
  KVM: arm64: Clarify the ordering requirements for vcpu/RD creation
  KVM: arm64: vgic-v3: Optimize affinity-based SGI injection
  KVM: arm64: Fast-track kvm_mpidr_to_vcpu() when mpidr_data is available
  KVM: arm64: Build MPIDR to vcpu index cache at runtime
  KVM: arm64: Simplify kvm_vcpu_get_mpidr_aff()
  KVM: arm64: Use vcpu_idx for invalidation tracking
  KVM: arm64: vgic: Use vcpu_idx for the debug information
  KVM: arm64: vgic-v2: Use cpuid from userspace as vcpu_id
  KVM: arm64: vgic-v3: Refactor GICv3 SGI generation
  KVM: arm64: vgic-its: Treat the collection target address as a vcpu_id
  KVM: arm64: vgic: Make kvm_vgic_inject_irq() take a vcpu pointer
