Description
When handling an IRQ, we may need heavier handling than what is possible in the IRQ handler (it may be in a special stack, and it runs with irq disabled).
We should add a marker somewhere in CPU-local memory or in a SPR in order to tell the exception handling code not to return to mainstream code, but go back in the kernel for some kernel hander code.
