Merge branch kvm-arm64/lpi-xarray into kvmarm/next

* kvm-arm64/lpi-xarray:
  : xarray-based representation of vgic LPIs
  :
  : KVM's linked-list of LPI state has proven to be a bottleneck in LPI
  : injection paths, due to lock serialization when acquiring / releasing a
  : reference on an IRQ.
  :
  : Start the tedious process of reworking KVM's LPI injection by replacing
  : the LPI linked-list with an xarray, leveraging this to allow RCU readers
  : to walk it outside of the spinlock.
  KVM: arm64: vgic: Don't acquire the lpi_list_lock in vgic_put_irq()
  KVM: arm64: vgic: Ensure the irq refcount is nonzero when taking a ref
  KVM: arm64: vgic: Rely on RCU protection in vgic_get_lpi()
  KVM: arm64: vgic: Free LPI vgic_irq structs in an RCU-safe manner
  KVM: arm64: vgic: Use atomics to count LPIs
  KVM: arm64: vgic: Get rid of the LPI linked-list
  KVM: arm64: vgic-its: Walk the LPI xarray in vgic_copy_lpi_list()
  KVM: arm64: vgic-v3: Iterate the xarray to find pending LPIs
  KVM: arm64: vgic: Use xarray to find LPI in vgic_get_lpi()
  KVM: arm64: vgic: Store LPIs in an xarray
