From 0c73a6a72a390a14baebd1b310bf925acb9e8075 Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Wed, 13 Jul 2011 20:29:24 +0200 Subject: [PATCH] m68k: Revive reporting of spurious interrupts commit 1ab5e47f928083b850c5bd2d90aef2de6b806bdb ("Change the m68knommu irq handling to use the generic irq framework.") removed the reporting of spurious interrupts on nommu (68328 and 68360). Bring it back in a generic way, using "atomic_t irq_err_count", as that's what most of the other architectures are using.
