Boqun Feng d06957d7a6 PCI: hv: Avoid the retarget interrupt hypercall in irq_unmask() on ARM64 ... On ARM64 Hyper-V guests, SPIs are used for the interrupts of virtual PCI devices, and SPIs can be managed directly via GICD registers. Therefore the retarget interrupt hypercall is not needed on ARM64. An arch-specific interface hv_arch_irq_unmask() is introduced to handle the architecture level differences on this. For x86, the behavior remains unchanged, while for ARM64 no hypercall is invoked when unmasking an irq for virtual PCI devices.
