From 08d33b27f7063ba2b4a29f9e3a2dcb65f30dec0b Mon Sep 17 00:00:00 2001 From: Marc Zyngier Date: Tue, 6 Sep 2011 13:27:10 +0100 Subject: [PATCH] ARM: GIC: Make MULTI_IRQ_HANDLER mandatory Now that MULTI_IRQ_HANDLER is selected by all the in-tree GIC users, make it mandatory and remove the unused macros.
