The init_IRQ() Function
Init_IRQ() is usually located in arch/<host>/kernel/irq.c. The Hitachi SH
version is in arch/<host>/kernel/irq_ipr.c.
Init_IRQ() initializes the hardware-specific side of the kernel's interrupt
subsystem. Interrupt controllers are initialized here, but their input lines
are not enabled until drivers and kernel modules call request_irq().
