| |
Reset the IRQ_NOAUTOEN and IRQ_NOREQUEST flags that are enabled by default on ARM. If IRQ_NOAUTOEN is set, __setup_irq doesn't call irq_startup, that is responsible for calling irq_unmask at startup time. As a result event channels remain masked.
The clear is already made in bind_evtchn_to_irq with commit a8636c0 but was missing in bind_virq_to_irq.
