From 213060a4d6991a95d0b9344406d195be3464accf Mon Sep 17 00:00:00 2001 From: Isaku Yamahata Date: Mon, 19 May 2008 22:13:40 +0900 Subject: [IA64] pvops: paravirtualize NR_IRQS Make NR_IRQ overridable by each pv instances. Pv instance may need each own number of irqs so that NR_IRQS should be the maximum number of nr_irqs each pv instances need.
