  xen: events: remove dom0 specific xen_create_msi_irq
  xen: events: use xen_bind_pirq_msi_to_irq from xen_create_msi_irq
  xen: events: push set_irq_msi down into xen_create_msi_irq
  xen: events: update pirq_to_irq in xen_create_msi_irq
  xen: events: refactor xen_create_msi_irq slightly
  xen: events: separate MSI PIRQ allocation from PIRQ binding to IRQ
  xen: events: assume PHYSDEVOP_get_free_pirq exists
  xen: pci: collapse apic_register_gsi_xen_hvm and xen_hvm_register_pirq
  xen: events: return irq from xen_allocate_pirq_msi
  xen: events: drop XEN_ALLOC_IRQ flag to xen_allocate_pirq_msi
  xen: events: do not leak IRQ from xen_allocate_pirq_msi when no pirq available.
  xen: pci: only define xen_initdom_setup_msi_irqs if CONFIG_XEN_DOM0
