Merge branch irq/plic-masking into irq/irqchip-next

* irq/plic-masking:
  : .
  : SiFive PLIC optimisations from Samuel Holland:
  :
  : "This series removes the spinlocks and cpumask operations from the PLIC
  : driver's hot path. As far as I know, using the priority to mask
  : interrupts is an intended usage and will work on all existing
  : implementations. [...]"
  : .
  irqchip/sifive-plic: Separate the enable and mask operations
  irqchip/sifive-plic: Make better use of the effective affinity mask
  PCI: hv: Take a const cpumask in hv_compose_msi_req_get_cpu()
  genirq: Provide an IRQ affinity mask in non-SMP configs
  genirq: Return a const cpumask from irq_data_get_affinity_mask
  genirq: Add and use an irq_data_update_affinity helper
  genirq: Refactor accessors to use irq_data_get_affinity_mask
  genirq: Drop redundant irq_init_effective_affinity
  genirq: GENERIC_IRQ_EFFECTIVE_AFF_MASK depends on SMP
  genirq: GENERIC_IRQ_IPI depends on SMP
  irqchip/mips-gic: Only register IPI domain when SMP is enabled
