The current cpu-private IRQ registration is ugly as it requires need to expose arch_unmask_irq() outside of intc code. So switch to percpu IRQ APIs: -request_percpu_irq [boot core] -enable_percpu_irq [all cores] Encapsulated in helper arc_request_percpu_irq() Signed-off-by: Vineet Gupta <vgupta@synopsys.com>
