From bf664c0a3a42683b78d74aca2d7cfb6ccc2aa2c3 Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Fri, 5 Jun 2009 03:13:11 -0400 Subject: [PATCH] Blackfin: fix sparseirq/kstat_irqs fallout The sparseirq changes (d7e51e66) played poorly with the Blackfin irqchip implementation as we're still using the old hardirq method. Our bad irq structure had a NULL kstat_irqs field so when all the common code tries to increment this field, everything goes big bada boom.
