Wei Liu	fb5ef35165	iommu/hyperv: setup an IO-APIC IRQ remapping domain for root partition ... Just like MSI/MSI-X, IO-APIC interrupts are remapped by Microsoft Hypervisor when Linux runs as the root partition. Implement an IRQ domain to handle mapping and unmapping of IO-APIC interrupts.

Wei Liu	e39397d1fd	x86/hyperv: implement an MSI domain for root partition ... When Linux runs as the root partition on Microsoft Hypervisor, its interrupts are remapped. Linux will need to explicitly map and unmap interrupts for hardware. Implement an MSI domain to issue the correct hypercalls. And initialize this irq domain as the default MSI irq domain.
