generic_handle_irq() is invoked from a regular interrupt service
routine. This handler will become a forced-threaded handler on
PREEMPT_RT and will be invoked with enabled interrupts. The
generic_handle_irq() must be invoked with disabled interrupts in order
to avoid deadlocks.
Instead of manually disabling interrupts before invoking use
generic_handle_irq_safe() which can be invoked with enabled and disabled
interrupts.
