Dexuan Cui 79aa801e89 PCI: hv: Use effective affinity mask ... The effective_affinity_mask is always set when an interrupt is assigned in __assign_irq_vector() -> apic->cpu_mask_to_apicid(), e.g. for struct apic apic_physflat: -> default_cpu_mask_to_apicid() -> irq_data_update_effective_affinity(), but it looks d->common->affinity remains all-1's before the user space or the kernel changes it later. In the early allocation/initialization phase of an IRQ, we should use the effective_affinity_mask, otherwise Hyper-V may not deliver the interrupt to the expected CPU. Without the patch, if we assign 7 Mellanox ConnectX-3 VFs to a 32-vCPU VM, one of the VFs may fail to receive interrupts.
