However, it might be worth experimenting setting the corresponding bits in the PACA as well, as this will diminish the latency of processing them. IE. local_irq_enable() will see the bit, generate an interrupt frame and call the handler which is a faster path than re-enabling MSR:EE and then taking an external interrupt.
