In driver/xen/events.c, whether bind_pirq is shareable or not is determined by desc->action is NULL or not. But in __setup_irq, startup(irq) is invoked before desc->action is assigned with new action. So desc->action in startup_irq is always NULL, and bind_pirq is always not shareable. This results in pt_irq_create_bind failure when passthrough a device which shares irq to other devices. This patch doesn't use probing_irq to determine if pirq is shareable or not, instead set shareable flag in irq_info according to trigger mode in xen_allocate_pirq. Set level triggered interrupts shareable. Thus use this flag to set bind_pirq flag accordingly.
