From a1ddc74a23c89ae236b163a3b0887f8c344aaa4a Mon Sep 17 00:00:00 2001 From: Marc Zyngier Date: Tue, 26 Aug 2014 11:03:17 +0100 Subject: [PATCH] arm64: 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.
