Used for external hardware interrupts. If this is the first external
hardware interrupt (i.e. not a nested hardware interrupt) then the
kernel switches from the current task to the interrupt stack. Like

- to increase the size of every per thread stack.

The interrupt stack is also used when processing a softirq.
