The top level IRQs, from the PIH, are well suited for handle_simple_irq() ... they can't be acked or masked. Switching resolves some issues with how IRQs were dispatched. Notably, abuse of desc->status, IRQ accounting, and handling of various faults. In short, use standard genirq code. Drivers that request_irq() to the PIH will need to pay more attention to things like setting IRQF_DISABLED (since it's no longer ignored), and making I2C calls from handlers (you'll need a lockdep workaround).
