In addition to consolidating the or1k-pic with other interrupt controllers, this makes OpenRISC less tied to its on-cpu interrupt controller. All or1k-pic specific parts are moved out of irq.c and into drivers/irqchip/irq-or1k-pic.c In that transition, the functionality have been divided into three chip variants. One that handles level triggered interrupts, one that handles edge triggered interrupts and one that handles the interrupt controller that is present in the or1200 OpenRISC cpu implementation.

SPR_SR_DSX bit is status register bit indicating whether

the last exception has happened in delay slot.

OpenRISC architecture makes it optional to have it implemented

in hardware and the OR1200 does not have it.

SPR_SR_DSX bit implemented. Say Y if you are unsure.
