    iommu/vt-d: Refine the interfaces to create IRQ for DMAR unit · 34742db8
    Jiang Liu authored
    Refine the interfaces to create IRQ for DMAR unit. It's a preparation
    for converting DMAR IRQ to hierarchical irqdomain on x86.
    
    It also moves dmar_alloc_hwirq()/dmar_free_hwirq() from irq_remapping.h
    to dmar.h. They are not irq_remapping specific.
