Module kernel::irq

IRQ abstractions.

An IRQ is an interrupt request from a device. It is used to get the CPU’s attention so it can service a hardware event in a timely manner.

The current abstractions handle IRQ requests and handlers, i.e.: it allows drivers to register a handler for a given IRQ line.
