Merge branch 'stable/irq.rework' into stable/irq.cleanup

* stable/irq.rework:
  xen/irq: Cleanup up the pirq_to_irq for DomU PV PCI passthrough guests as well.
  xen: Use IRQF_FORCE_RESUME
  xen/timer: Missing IRQF_NO_SUSPEND in timer code broke suspend.
  xen: Fix compile error introduced by "switch to new irq_chip functions"
  xen: Switch to new irq_chip functions
  xen: Remove stale irq_chip.end
  xen: events: do not free legacy IRQs
  xen: events: allocate GSIs and dynamic IRQs from separate IRQ ranges.
  xen: events: add xen_allocate_irq_{dynamic, gsi} and xen_free_irq
  xen:events: move find_unbound_irq inside CONFIG_PCI_MSI
  xen: handled remapped IRQs when enabling a pcifront PCI device.
  genirq: Add IRQF_FORCE_RESUME
