The decision on whether to use hardware APIC virtualization used to be taken globally, based on the availability of the feature in the CPU and the value of a module parameter. However, under certain circumstances we want to control it on per-vcpu basis. In particular, when the userspace activates HyperV synthetic interrupt controller (SynIC), APICv has to be disabled as it's incompatible with SynIC auto-EOI behavior. To achieve that, introduce 'apicv_active' flag on struct kvm_vcpu_arch, and kvm_vcpu_deactivate_apicv() function to turn APICv off. The flag is initialized based on the module parameter and CPU capability, and consulted whenever an APICv-specific action is performed.
