Merge branch 'pci/host-vmd' into next
* pci/host-vmd: x86/PCI: Add driver for Intel Volume Management Device (VMD) PCI/AER: Use 32 bit PCI domain numbers x86/PCI: Allow DMA ops specific to a PCI domain irqdomain: Export irq_domain_set_info() for module use genirq/MSI: Relax msi_domain_alloc() to support parentless MSI irqdomains
