From a71b092a9c68685a270ebdde7b5986ba8787e575 Mon Sep 17 00:00:00 2001 From: Marc Zyngier Date: Tue, 26 Aug 2014 11:03:18 +0100 Subject: ARM: Convert handle_IRQ to use __handle_domain_irq In order to limit code duplication, convert the architecture specific handle_IRQ to use the generic __handle_domain_irq function.
