A couple of patches I've applied for v4.4 relating to 4KB stack support
with SMP. Basically 4KB stacks never quite worked with SMP since the IRQ
stack was never set up on secondary threads. This causes boot failure if
enabled accidentally.

The first patch sets up and tears down the IRQ stack state, and the
second is just a small clean up to avoid bit rot.
