From c0ad90a32fb60f4129d0e24dfd5fd7128e2e09f2 Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Thu, 29 Jun 2006 02:24:44 -0700 Subject: [PATCH] genirq: add ->retrigger() irq op to consolidate hw_irq_resend() Add ->retrigger() irq op to consolidate hw_irq_resend() implementations. (Most architectures had it defined to NOP anyway.) NOTE: ia64 needs testing. i386 and x86_64 tested.
