Hi,
In the current kernel, the external proxy works pretty well with the lazy
EE. But it still treat the external input interrupt as level sensitive
and would hard disable the irq while a interrupt occurs with irq soft
disabled. This patch series enables PACA_IRQ_EE_EDGE support for book3e
and will leave the irq still hard enabled while a external interrupt
occurs with soft irq disabled. This passed the boot test on T4240QDS
board.
