KVM: PPC: Book3S HV: Tunable to disable KVM IRQ bypass
Add a module parameter kvm_irq_bypass for kvm_hv.ko to disable IRQ bypass for passthrough interrupts. The default value of this tunable is 1 - that is enable the feature. Since the tunable is used by built-in kernel code, we use the module_param_cb macro to achieve this.
