KVM: arm/arm64: register irq bypass consumer on ARM/ARM64
This patch selects IRQ_BYPASS_MANAGER and HAVE_KVM_IRQ_BYPASS configs for ARM/ARM64. kvm_arch_has_irq_bypass() now is implemented and returns true. As a consequence the irq bypass consumer will be registered for ARM/ARM64 with the forwarding callbacks: - stop/start: halt/resume guest execution - add/del_producer: set/unset forwarding at vgic/irqchip level We don't have any actual support yet, so nothing gets actually forwarded.
