Subject: [RFC PATCH 06/14] ARM: exynos4: convert to CONFIG_MULTI_IRQ_HANDLER
Date: Fri, 23 Sep 2011 17:51:24 +0100 [thread overview]
Message-ID: <1316796692-15964-7-git-send-email-marc.zyngier@arm.com> (raw)
In-Reply-To: <1316796692-15964-1-git-send-email-marc.zyngier@arm.com>
Convert the Exynos4 platforms to be using the gic_handle_irq_offset()
function as their primary interrupt handler.
