Spurious interrupt on ARM.

Looking at hal/arm/arch/current/src/vectors.S in IRQ:

We increment the scheduler lock and decrement it again in interrupt_end.

In the case of there being a spurious interrupt, we don't callinterrupt_end, and so the scheduler never gets decremented.


Am I missing something here?
